Through a combination of chiropractic adjustments, therapeutic exercises, and personalized treatment plans with each session, I experienced noticeable improvements physically. Not only did my pain diminish but I also regained a sense of vitality and mobility that I thought I had lost.
What truly sets Dr. Sadr apart is his commitment to empowering his patients. He took the time to educate me about proper posture, ergonomics, and lifestyle modifications that would support my recovery and prevent future injuries. His personalized approach to care made me feel valued as an individual, and I always felt supported and encouraged throughout my journey to wellness.
Thanks to Dr. Sadr’s expertise and unwavering support, I am now able to enjoy life without the burden of chronic pain weighing me down. His compassionate care has truly been a lifesaver, and I am forever grateful for the positive impact he has had on my health and well-being.

Dr. Shahed!!! I’d give 10 stars if I could. Extremely intelligible and wise. Understanding and instructive. Super amazing staff! I’m extremely grateful I’m a member. Please visit if you’re in pain. Work on your muscles and allow them to help with your joints!

I’ve been to maybe 10 other locations and this one is the best by far! Dr. Shahed Sadr, DC treats you as a personal patient vs just a quick in/out adjustment.

Tim G.

Initially, my range of motion was severely limited, and exercising was impossible when I started seeing Dr. Shahed. Even using a pillow resulted in pain. After 2 months of physical therapy and adjustments, I now have complete range of motion and am pain-free.
I wholeheartedly endorse Dr. Shahed; he offers immediate relief and educates on exercises and stretches for ongoing relief at home.

David M.

as someone who has seen several chiropractors and physical therapists over the years, I can honestly say Dr. Shahed yielded the most results. His techniques are more than just some exercises, it’s about mind and muscle connecting to heal the body from within. In 6 sessions I experienced knee and ankle relief that I couldn’t find in PT or personal training. There is work behind the healing, it’s not a one time crack that will fix you, but as the saying goes give a man a fish and you feed him for a day, teach him to fish and give him a pole and you feed him for a lifetime.
Dr. Shahed provides the knowledge and training to fix yourself longterm
