Bruce Hamby, PA-C, specializes in helping patients reclaim their energy, sharpen their focus, optimize their bodies, and feel like themselves again.
With extensive experience in hormone optimization, metabolic health, peptide therapies, and medical weight management, Bruce works with individuals who are tired of being told their symptoms are “normal.” Fatigue, brain fog, stubborn weight gain, low libido, poor recovery, disrupted sleep — these issues may be common, but they are not inevitable.
Bruce’s approach is highly individualized, data-driven, and results-focused. Every treatment plan is designed around precision diagnostics, modern therapeutics, and a deep understanding of how hormones, metabolism, and lifestyle intersect to influence performance, aging, and overall vitality.
Patients often seek Bruce when they want more than symptom management — they want optimization.
Known for his direct, honest, and highly engaging style, Bruce partners closely with patients to create clear strategies that deliver measurable improvements in how they feel, function, and perform. His focus extends beyond short-term fixes toward building long-term resilience, healthspan, and quality of life.
Whether the goal is restoring vitality, improving body composition, enhancing cognitive performance, or simply feeling “like you again,” Bruce brings a modern, science-forward approach to helping patients operate at their best.

What Clients are Saying
I started my weight loss journey in November 2023 and have lost 65 pounds — and kept it off since Christmas 2024. I haven’t done an injection in over 7 months and the weight is still off!
Trimm Off changed my life. I had tried every diet and never felt like myself. A few pounds would come off, but nothing stuck — and it never helped me change how I felt or managed my mindset.
Within months of working with Trimm Off, the results were undeniable. The food noise was gone, I stopped binge eating, and I finally learned how to fuel my body the right way. Two years later, I genuinely crave healthy food — but don’t get me wrong, I’ll still enjoy a good cheeseburger!
And now in 2026 I still haven’t gained any of the weight back!!! I’m just so thankful! Now, I feel confident. I enjoy dinner parties and order what I want without guilt. I like who I see in the mirror — and my kids see a mom who’s active, strong, and healthy. I’ve referred 30+ people to Trimm Off and will never stop singing their praises.
Dr. Williams is amazing — she listens, trusts what you’re saying, and works with your body, not against it. When I was sick and my PCP didn’t respond, Carolina and Dr. Williams had a prescription to me within an hour. I’m so grateful I made this choice for my health!
