When I was introduced to DeSean, I was struggling with my weight and maintaining a fitness regimen. Right away, DeSean made me feel comfortable and developed an approach specific to me including a nutrition plan and exercise schedule. He shares knowledge every time we train and incorporates multiple exercises to keep the sessions fresh and new. He also challenges me to go beyond my perceived limits, so I continue to develop and grow. I now feel more confident, I’m losing weight, I can see muscle definition and I feel great. I appreciate DeSean’s patience and passion for fitness and recommend him to anyone wanting to reach goals and get results.

Coach De takes pride and passionately strives to be at the top of his game. He pushes his clients to develop individually and as a team player to strive for a high level
