EXCELLENT Based on 31 reviews Posted on Google Andre BriscoTrustindex verifies that the original source of the review is Google. I came to Gryffon Performance because I felt like I had completely plateaued with my workouts. From day one, David identified that I had been lifting with improper form for years, which explained why I wasn’t seeing the results I wanted. Not only did he help me get stronger and more defined, but he also took the time to teach me the correct techniques and the “why” behind every exercise. His coaching gave me the knowledge and confidence to continue making progress long after I left. Even after moving back to DC, I’m still applying everything David taught me. If you’re serious about breaking through a plateau, improving your technique, and getting real results, I can’t recommend Gryffon Performance enough.Posted on Google Darline Jean-BaptisteTrustindex verifies that the original source of the review is Google. I’ve been training with David for almost months now, and I’m so glad I started. Since then, I’ve leaned out, built muscle, and become so much stronger. I’ve also gained a lot more confidence in the gym and actually look forward to our sessions. He takes the time to make sure you’re doing every exercise correctly, keeps you motivated, and knows exactly how to push you to get the best results. He’s professional, encouraging, and genuinely cares about helping his clients reach their goals. I would absolutely recommend him to anyone looking for a knowledgeable and supportive personal trainer!Posted on Google JosephTrustindex verifies that the original source of the review is Google.

Best gymPosted on Google Nakia JacksonTrustindex verifies that the original source of the review is Google. I can’t recommend my personal trainer enough! From day one, David took the time to understand my goals and created a plan that was challenging, realistic, and tailored specifically to me. Every workout is well organized, motivating, and pushes me to become stronger while maintaining proper form and preventing injuries.

Absolutely incredible facility and had some of the best gym experiences ever with David. Fair prices, made me a great meal plan, and helped reignite the spark for fitness and health. Give him a call when you’re ready to change your life!Posted on Google Cean SlaughterTrustindex verifies that the original source of the review is Google. Embarking on a fitness journey can be both exciting and challenging. It involves not just physical changes but also mental and emotional growth. Given my situation, i’ve reached milestones with previous trainers but felt frustrated when programs changed as my body started to transform. David’ fitness philosophy and objectives has surpassed my expectations and has yielded the peak of my results in just 12 weeks. He’s provided a balanced diet: which fuled my workouts with proper nutrition tailored to my goals. My fitness journey is unique —it’s a blend of physical effort, emotional resilience, and mental clarity. Having someone like David to guide me and hold me accountable is an advantage, and leveraging a structured approach has facilitated my progress. Oh, and the facility is also motivating becaue of the machine options.Posted on Google Morgan AlexanderTrustindex verifies that the original source of the review is Google. David has been the best.

I’ve been training with David since early February and from the begin he has been great. Fitness journeys can be challenging and overwhelming to stay consistent with at times but David has helped me stick with it by being flexible and holding me accountable. He is very informative, relatable, and ensures to check on you every step of the way. He makes sure your goals, meal plans, and work outs are challenging yet attainable so that you stick with them while pushing you forward the whole way. If something’s not working for you, he will work with you to determine what does so you stick with it. It’s definitely a one day at a time process and I’m looking forward to future results!Posted on Google Chastity WhiteTrustindex verifies that the original source of the review is Google.
