I've been working with Kevin for the past 2 months, and I couldn’t be happier with the results! From the very first session, he took the time to understand my goals, fitness level, and any limitations I had. He made personalized workout plans which have been very helpful.

What sets Kevin apart is his genuine passion for helping clients succeed. He always encourages me to do my best while keeping things fun and enjoyable. I did pilates for more than 2 years previously but has seen more results from the past 2 months that I worked with Kevin.
If you’re looking for a trainer who is knowledgeable, supportive, and truly invested in your progress, I highly recommend Kevin.

I’ve been training with Kevin for 2 years and the experience has been amazing! From the very first session, it was clear that Kevin is not only highly skilled but also genuinely invested in helping me reach my goals. They took the time to understand my fitness level and crafted a personalized plan that’s been both challenging and rewarding.

What really sets Kevin apart is their ability to motivate and encourage me during every session. They push me to my limits while always maintaining a positive and supportive attitude. I’ve made significant progress—whether it’s building strength, increasing my endurance, or just feeling more confident in my body.

In addition to their expertise, Kevin is always punctual, professional, and easy to communicate with. They’re always available to answer questions or adjust my workout plan as needed, which makes training with them feel like a truly collaborative effort.

If you’re looking for a knowledgeable, motivating, and dedicated personal trainer, I can’t recommend Kevin enough. They’ve truly helped me transform my fitness routine and achieve results I didn’t think were possible

Kevin is a very professional fitness trainer. He is very knowledgeable in fitness training and in self defense. He listens and provides advice for his client's need to achieve one's goal. He is very patient and fun to work out with. He is very flexible with my schedule when I have conflicts at times. I highly recommend Kevin as your personal trainer.

I would highly recommend Kevin as a personal trainer. He is very experienced at what he does since he has over 10 years of experience as a trainer. During training sessions, Kevin not only gives explanations about proper form and what each exercise does for the body, but he also uses the knowledge that he has as a licensed physical therapist assistant to offer advice regarding diet and recovery.

When I first met Kevin, he was very thorough when asking me what my fitness goals were. We set short and long-term goals and made a plan. Kevin has a 10 years of experience as a personal trainer, holds a bachelor’s degree in kinesiology, and is licensed by the state of California as a physical therapist assistant—so he is highly educated and experienced. As a trainer, Kevin is very patient and ensures that you understand what muscles to feel and why we are doing each exercise. Before I started working out with Kevin, I had no idea how to build muscle, burn fat, and get stronger. Now, I feel confident when I workout because all that I learned from Kevin.

I had the privilege of getting a chance to train with Kevin. Based off of how much experience he has with training (10+ years) along with the fact that he is also a licensed physical therapist, I knew I would be in good hands. I enjoyed his attention to detail when it came to making sure I was getting a proper “stretch” for muscle tension during my chest workout. Thank you once again for the helpful advice and for the intense workouts Kevin!

Kevin is a true professional! I started training with Kevin this year as a 73 year old retired nurse, and newbie to weight lifting. As an “older” client with several health issues, I especially appreciate Kevin’s knowledge base in kinesiology and physical therapy. He understands how the body works, which allows him to keep me safe and injury free while pushing me to maximize my potential. I have gained strength and muscle and am shocked to find myself deadlifting over 100 lbs and working toward my body weight!
Train with Kevin! You won’t be sorry!

Kevin is very knowledgeable in fitness and physical therapy.
When I first got into the gym, I was very unsure about how to lift weights properly.
Kevin has 10 years of experience in physical therapy and personal training and it shows!
After training with Kevin, I feel more sure of myself when I train alone.
If you are looking for a personal trainer who is knowledgeable and thorough and patient, I would definitely give Kevin a try.
