More About Coach Garrett

I have over 10 years coaching experience in multiple sports and as a strength and conditioning specialist. I have coached and trained athletes and individuals of all age groups - from youth to adults, preparing them to achieve weight loss goals, team sport competitions and individual athletic events.

I have held strength and conditioning positions with the Temecula Halos youth baseball, San Diego Mesa College football, San Diego Enforcers semi-pro football and San Diego Power Surge Softball. I'm a proud member of the NSCA and NASM, holding certificates in personal training and speed/agility/quickness.

A note on the Cov-19 situation - It is very easy for me to abide by the guidelines of leading scientific organizations to keep everyone safe. All of my instruction is done outdoors in wide open spaces.

Played high school football, basketball and was also a 100m, 200m, 400m sprinter (track and field)
Played a season of football at Kent State University, Kent, OH. (Awesomely horrific experience! ask me about it sometime)
Played semi-pro ball with Southern Michigan Timber Wolves, Michigan Twisters and SoCal Predators.
Continue to enjoy sprinting, weightlifting and HIIT style workouts

All workouts are well balanced and thorough. Workouts include pre-workout muscle prep, mobility work, dynamic/active stretching, core prep, strength training and flexibility. Depending on the client's goals, I will also work in plyometrics, SAQ and explosive/power exercises.

Client Reviews

very detailed, helpful, impactful, and concrete exercises from coach Garrett.

Garrett is an awesome coach, always accommodating & giving great advice & coaching tools! My son feels more confident in his skills & abilities. Thank you for the work you do.

My son enjoys his sessions with Garrett

After 1 session, my son is excited to continue with Coach Garrett. His input has been very insightful and thorough and we are confident in his ability to provide what we are looking for! I would definitely recommend his services.

We had our first session with Coach Garrett this weekend. He is great; very professional, explains everything and follows social distancing guidelines. I'll definitely book more sessions and think our son will really benefit from the coaching.

He is an awesome coach great at what he dose and is always positive which is awesome!!!!

Awesome. Very positive. Very thoughtful. Very helpful.

Coach Garrett has been working with my 15 year old for a few months now. He has been a great motivator and teacher. The thing that is particularly impressive about Garrett is that he gives open, honest feedback throughout the sessions. He is not a pure rah-rah coach always telling the kids they're doing awesome (when they're not) but he also doesn't try to drive improvement through negative reinforcement. Every session is a solid routine of strength, flexibility and agility followed by a focus on mechanics and football knowledge. Definitely recommend him to others.

Coach Garrett was absolutely amazing, his personality and the way he worked with my son was great!

(no details provided)

Coach Garrett is fantastic! My 10 year old son is learning to play football and we needed a coach that was willing to start with the basics. Coach Garrett is positive and enthusiastic, and made my son feel great about himself. He is professional, knowledgeable, and motivating. We'll definitely be signing up for more lessons.

My son AJ really enjoyed his first session with Coach Garrett. Coach covered a number of techniques in order to improve my son’s QB skills and did so in a very engaging way. My son is looking forward to his next session with Coach Garrett. This 1:1 coaching/training has me looking forward to seeing my son play next season already.

Garrett is a great motivator for our daughter and is teaching her some great foundations for being a faster, stronger athlete!

Coach Garrett was great in my son’s first training with him. He had a great attitude and really made my son feel comfortable. I really liked that he explained concepts to both my son and I. He is a great coach and I really liked forward to having him work with my son.

First encounter boys were exhilarated...now discovery begins

Awesome teacher! Really knows his stuff and very excited.

So far coach Garrett has been very good for my son (HS sophomore football). He is very thorough when it comes to muscle training, emphasizing a balanced approach and very aware of injury risks. He also gives a lot of advice regarding form and technique when it comes to actual football play. Finally, and very importantly, he is fun, positive and extremely motivating.

He's an incredible coach, highly motivating and infinitely more knowledgeable than an average youth coach.

Nice session.

Coach Garrett is fantastic! First session with my 13 yr old son went great. My son is excited for his next session and eager to keep learning the fundamentals he'll need to start football. Coach Garrett's other 5 star reviews are spot on. Highly recommended.

Update: My son is about to complete his 8th session with Coach Garrett. The training sessions have been fantastic. My son's knowledge and abilities have grown exponentially. My son starts summer practice in a few days and he feels confident and ready to continue his training with his school team. He wants to continue with Coach Garrett when his season starts as well. Thanks Coach!

First session was great. My son responded well to Coach Garrett and we're going to book more sessions for this summer.

Exactly what my kid needed. Thanks!

My son loves playing basketball.
In last year, he went for 6th grade basketball team tryout in his school but sadly did not make the cut. We decided to give it one more try this year, and this time we decided to get some professional help from coach Garrett...
Long story short, thanks to Coach Garrett, my son is now playing starting five in his school team.

Coach Garrett is highly motivating. His sessions are structured extremely well & tailored to fit my son's need; stretching, warm up, foot works, game drills,...etc. Highly recommend coach Garrett.

Coach Garrett is very experienced and knowledgeable in his field. My 12 yo son really enjoyed his first lesson and is looking forward to future lessons with him. Highly recommend!

First session was great !

Coach Garrett was very good with my son. My son enjoy the training and feels he has a improved a little within the 2 session.

(no details provided)

Our experience with Coach Garrett was exceptional and we are looking forward to more sessions. My son is heading into his first year of high school football with very little experience. Coach has provided him with tips and techniques to ensure he understands his position, builds strength and resiliency, and has a firm understanding of the why behind every move he makes. It is a level of attention he would not otherwise get with the size of his current team. Coach also has a great rapport with my son and makes him feel comfortable. A very motivating coach. My son is having fun and has had a big boost in confidence.

Coach Garrett helped tremendously on footwork and quarterback mechanics, but even better was how effective he is in simple communications and positive enforcement.

1st session was awesome.
Coach gave my Son great advise and explained to him the basics of his position, more than I could ever think of.
My Son Jerry was very happy and we can’t wait to continue in the learning experience.

Coach Garrett was outstanding. He made my 15 year old son feel very comfortable from the moment they meet. He has a vast knowledge of football as well as athletic training. I was impressed that he focused on building a total athlete as well as a football player. My son is looking forward to more training sessions with Coach Garrett.

Great first session with Coach Garrett. He attitude was extremely positive and my 13 yr old son really enjoyed the interaction with him. He did very well explaining the drills and the why behind it as well. Very knowledgeable and we will definitely be getting more sessions with Coach Garrett.

Great job! My son really liked working with Garrett and learned a lot.

Amazing coach to learn from !

Coach Garrett is a highly motivating and encouraging trainer. He is very professional and works well with kids. He knows just how to bring out the best in them! His cheerful attitude and positive reinforcement will help any level athlete. We look forward to our son working with him this season.

We really liked Coach Garrett. He has an incredible talent of recognizing at what stage his athlete is and training to elevate his athlete's performance to another level in just one session. Can't wait for the next session. I would recommend Coach Garrett to anyone looking to improve their skills and confidence.

I was impressed with what I saw from Coach Garrett in the first training session with my 12 year old son. I was looking for improvement in receiving skills and confidence and my son got both in the first session. I saw fast paced drills, attention to detail, high energy and encouragement from Coach Garrett. My son is looking forward to his next session.

Diego really saw useful all techniques coach Garret worked with him and can't wait for next session.

Coach Garrett is undoubtedly versed with the position he coaches. In particular, he provided my son valuable insight to improve on his receiving skills. Further, he exercises positive critiquing (not breaking a person down when making a mistake, rather building them up to improve).

Coach Garrett was terrific. He is training by my son and connected with him immediately. He worked him hard but inspired him all the way.

Our son has made a complete turnaround. who he was before Coach Garret is nothing compared to what we are seeing today. He is motivated and determined.

My son has Coach Garrett as a personal coach. He plays Defensive End and back up Quarterback. We initially booked these sessions with the intention of working on his core strength due to a shoulder injury. My son's high school coach swears that my son has a gift of being an amazing quarterback but he just didn't have the self confidence to take the role. After his first session my son was already showing interest of maybe taking on that role next season.

Coach Garrett's coaching style is exactly what my son needed. He's not a screamer and explains exactly why they do different drills. He encourages his players to ask questions and he performs the drills side by side with his players. My son has a smile on his face the whole session and can't wait to give up his early Sunday morning each week. If Coach Garrett was closer we would do multiple sessions a week. We drive an hour and a half for an hour session on a weekly bases but it's well worth it!

Great on our second day. Dominic still excited to go back.

After one session I already learned a lot of things. I love his coaching ways. I look forward to seeing Coach Garrett again.

Coach Garrett was awesome! He really knows how to teach kids and my hubby learned some pointers from him too! We are excited to keep working with him!

Hes very knowlodgeable and is a very good coach. My brother loved him as a coach and cant wait to be trained by him again.

Coach Garrett is definitely First class, top notch. My son is already improving. He pays attention to the details and teaches proper technics and fundamentals.
He always has a positive attitude and welcomes feedback or questions. Would definitely recommend him to other parents looking for a great coach.

Coach Garrett is an amazing coach. He has really been able to hone in on my son's skills and work with him to become the type of player he wants to be. Coach Garrett breaks down the drills and moves so that my son is able to easily understand what is expected of him and how to safely and properly execute the different plays. Part of our focus is in improving my son's athleticism / conditioning and the other aspect is the more technical aspect of playing the quarterback position, Coach Garrett provides an excellent balance of both of these focuses and continues to keep the practices lighthearted and fun. My son leaves practice knowing exactly what he needs to work on to improve. It's been a long time since I've seen him so focused and engaged and excited for the next session.

Great conditioning, skills, and strategy offered by coach Garrett. Coach has a terrific attitude and is always encouraging our son.

Coach Garrett is the best thing that has happened to my son's ability to explode and change directions with quick bursts of speed. I have coached my boy his whole life, which has limited him. Coach Garrett teaches all the movements with techniques that I have always skipped. My son enjoys his work outs now and has made more head way in two practices with Coach Garrett hen he did all summer last year with his running coach.

My son has been really happy working with Coach Garret. His HS coaches have said whatever you are doing with him keep doing it. My other son is now going to start working with Coach Garret as they play totally different positions. My boys like his methods, demeanor and teaching style. They relate to him well.

Excellent coach. Very sociable and informative. Always leaves me with new tools to work on during the week.

Great coach and a really good guy. Passionate and helps improve your game a lot and always keeps in contact. I Highly recommend no matter what position you play. Helped out with my athleticism and position specifically. I've played in the Marine Corps league and I've slowed down a whole lot since I deployed and when I started working with him my speed, agility and footwork were brought up more than up to speed and destroyed bad habits.

Our 6 year old son is so excited for his next session! After just one lesson he already learned so much. It has already helped with his confidence.

You simply will not find a better coach than Garrett Clark. He embodies all the qualities of the best coaches, and then adds some unique attributes of his own. He's extremely knowledgeable across the spectrum he needs for football, from conditioning to position technique; he gives the perfect blend of critique and confidence-building praise; his attitude and energy is outstanding; and he loves the game and it comes through in his work. This is the coach you want!

Coach Garrett is awesome....knows what he is doing and is very good at teaching you new things...help me improve my game within a hour

So far Coach Garrett is awesome! We are only in session 3 now and I really like that he has an exceptional attention to detail. My son really likes him as well. I'm looking forward to seeing the progression! I would recommend Coach Garrett to anyone looking to improve in speed, agility or overall football player!

Enthusiastic, high energy, very positive!! Perfect coach for building a players self-confidence!

I can't say enough about the impact Coach Garrett has had on my son. My sons athletic ability has grown tremendously in the weeks he's been training with Garrett. He's got a lot of patience and a wonderfully positive attitude, my son always looks forward to his sessions. I'm so happy to have found such a great person/Coach to work with my son, my only regret is not finding Coach Garrett sooner.

My son just completed his first two sessions with Coach Garrett and both sessions were great. My son is really enjoying it. Coach Garrett has a very positive and supportive approach. Thanks to Coach Garrett, my son is challenged and motivated. I also appreciate the detailed feedback Coach Garrett sends after each session. We're looking forward to continuing the training with Coach Garrett.

Great first time experience, help and motivates you to want to get better and achieve greatness

Coach Garrett is an amazing coach! He has already done wonders with our almost 7 yr old (yes not even 7!!) son and his football skills! He is teaching him how to really refine his receiving abilities, works footwork drills, & makes each session fun! Our son is loving the one-on-one coaching and Coach Garrett's personality and ability to teach skills and fun are truly remarkable!! Thank you!

We have had four sessions with Coach Garrett... My son is 7 years old and had to start playing QB for his flag football team. I having no experience with QB sought help online and we were lucky to find Coach Garrett. I have seen a lot of improvements in my son in practice and it is starting to translate to the games. Coach Garrett is awesome with my kid and obviously knows how to talk to young children (unlike a lot of coaches out there). He always provides positive reinforcement, which is something I even forget to do at times. I have fun watching them work together and hope to continue our relationship with Coach Garrett in the future!

Coach Garrett was great with my son during his fist session. I will be booking him again.

Coach Garret was great. My son really enjoyed his work out session. He is very patient and thorough with his workout.

Coach Garrett went from a great coach on paper, to an outstanding coach immediately. Modest in nature, his ability to just take a minute and create an opportunity to get to know the person behind the player demonstrated humility. He instantly displayed effective communication, consistency, and encouragement. Coach Garrett isn't just present for the session, he invests time with an articulate mind and training plan for the next time. My 11 year old son can summarize that being a good coach comes down to being a good person, and sometimes intelligence of the game doesn't make the coach better. But, there is no doubt that coach Garrett is both intelligent and genuinely a good person who cares about the individual he's coaching.
Here's some of my highlights:
•asking appropriate questions, using demonstrations, providing clear explanations, active listening, and observation
•motivates through being enthusiastic, encouraging, and actively leading.
•being able to develop a mutual trust, respect and commitment
•patient, open-minded, fair, knowledge of the game, adaptable coaching style and empathetic.
Finally, watching my son gain confidence and smile at his achievements is worth every penny.
Thanks Coach Garrett!

Hi talked to my son and he is very happy about your services. I am so glad you are able to teach him great techniques! I am hoping to continue for more but may need to figure out how much I can contribute for June. I will have to make payment by mid June for next 4 sessions.

Coach Garret C, was great!!! He very quickly responded to my questions and emails. He was accomodating about travel and time constraints. Today my son had his first one on one training with Coach Garrett. My son is a freshman wide receiver. He felt it was really helpful. He had a great first impression with Coach Garrett. There was an immediate bond. The session was more than I could have hoped for. We are immediately booking more sessions! Already I see my son learning more. GREAT COACH!!!
