We Don’t Just Count Calories—

We find the cause

Most weight loss programs treat symptoms. We treat the system.
With advanced diagnostic testing we uncover the underlying reasons behind weight gain—hormonal imbalances, inflammation, poor sleep, stress, gut dysfunction, and metabolic slowdowns.
“We don’t treat symptoms — we treat systems.”
— Dr. Mahmood Siddique, Medical Director
Our programs combine medical science, functional medicine, and integrative therapies to help you lose weight safely — and keep it off for good.

Best place for weight loss
Google-verified review
Best place for weight loss. Fantastic staff and Isabelle is my reason for the extra work. She makes my weekly visit so pleasant and she is so encouraging and sweet
Gold Standard
Google-verified review
Most patients feel more anxiety over medical billing than the procedures themselves, but Sleep and Wellness Medical Associates excels in both care and billing support. LuLu, Ruby, and Tilat are exceptional—patient, thorough, and committed to ensuring every bill and insurance question is clearly explained. They truly set the gold standard for medical billing services.
Healthy Transformation
Google-verified review
Before finding Dr. Siddique and Sleep and Wellness Medical Associates, I saw multiple doctors and traveled across the state for appointments. That all changed once Dr. Siddique coordinated my care and helped me get healthy—I no longer need to juggle multiple providers because I’m fully cared for at SWMA. I now sleep better, my health numbers are within range, and I continue to benefit as the practice expands services to include weight loss, healthy transformation, and laser-based treatments.
Lost 50 Pounds
Google-verified review
It is not an understatement to say that Dr. Siddique, Dr. Fisher, and Beverly Hodsden, LPC, have truly changed—and saved—my life. When I first came to Sleep & Wellness Medical Associates, I was in poor health, struggling with obesity, uncontrolled blood sugar, severe osteoarthritis, and depression due to a diminished quality of life. Their holistic approach, combining diet, medication, physical therapy, and psychological counseling, addressed both my physical and mental health. Dr. Fisher’s physical therapy is especially unique—she works one-on-one for 45 minutes, creating highly personalized routines that incorporate techniques like yoga and Pilates when appropriate.
