Patient Reviews

They were just wonderful. The staff was efficient and friendly, the procedure went smoothly, and I am home recuperating with clear instructions. They made an unpleasant procedure much easier. Thank you.

They are the best of the best! So professional! So respectful! And do just amazing work! From the front desk to the nurses to the Dr. Highly recommend them for anyone who is in need . They respond quickly and they get you in for your procedures very quickly. Beyond blessed to have found them.

I met Dr. Sandeep from a recommendation from my gynecologist. He treated my uterine fibroids. Without surgery, he was able to shrink the fibroids using an alternative way by blocking the blood flow through the vein. I just had my 1 year follow up with him and his procedure has helped with the pain.
