    Staff is very efficient. My only complaint is “bait and switch” . i’ve had several appointments here for different body parts and a couple of times. I had an appointment with the doctor and I ended up seeing the PA who is going to “ get you started” and I never saw the doctor.

  • Dr.Ali Zahrai, is an amazing doctor. Years ago he did back surgery on me & it was a success! Then recently I had a problem with my SI joint on both sides of my body. Dr. Zahrai came up with a procedure using robotics. The surgery went very well & I healed quickly with minimal pain. I would suggest & encourage anyone to see what he can do for you!
