Client Success Stories

The doctor-patient relationship is built on two-way communication, trust, and respect. Dr. Temkin takes the time to build all three of these important aspects of the relationship with his patients and personally I return the same to him. This allows for a common understanding and stronger bond to our mutual respect and goal of improved health.

“Joining the LeanMD program with Dr. Temkin was one of the best decisions I’ve ever made. The medically supported plan made losing weight feel safe and achievable. No gimmicks, no starvation, just real food, and smart guidance. I lost more than 25 pounds in a few months and have never felt more confident. The team genuinely cares about your success and keeps you motivated the entire way.”

“I originally came in because of low energy and slow recovery from workouts. I didn’t expect hormone balance to make such a huge difference, but it did. My strength is back, my sleep is deeper, and I don’t feel burned out all the time anymore.”

I've been going to Dr. Temkin for years now and I've stuck with him, because he listens to his patients and truly cares. It's always a great chat when having to go too. The vibe of the office is clean, modern, and makes you feel comfortable too. I recommend him to anyone!

“Dr. Temkin and the LeanMD team made my weight-loss journey feel structured and achievable. There’s no fad dieting here, just science, support, and real results. I dropped weight steadily, learned how to eat in a way that works for me, and felt amazing. I highly recommend this program to anyone wanting lasting change.”

“My biggest fear was feeling over-medicated or unnatural, but bioidentical hormones felt surprisingly subtle and normal. Over time my mood stabilized, my anxiety dropped, and my skin even improved. I feel more like myself than I have in a very long time.”

“The personalized approach at LeanMD was exactly what I needed. I didn’t feel judged — just supported every step of the way. The nutrition coaching was easy to follow, and the results were real. I lost weight steadily, felt more energetic, and finally developed healthy habits that stick.”

“I’d tried countless diets before, but nothing worked long-term until LeanMD. Dr. Temkin and his team helped me understand how to eat properly with sustainable meal plans that fit into my busy life. The encouragement and support made all the difference. I’ve not only lost weight but I’ve kept it off.”
