  • Dr Gorab is incredible. His work is perfect. His bedside manner is amazing, made me feel very comfortable with the procedure. Susan is also great at explaining the post op process.

  • In September 1998 Dr. Gorab did hip surgery, I was 46. I was born with a dislocated hip, and I was 5 years old when I had my first surgery. I'm 70 years old and have had no pain or any complications and I love to dance😍 God Bless you Dr. Gorab🙏

  • The best decision I made was working with Dr. Gorab for my total hip replacement. Far and away the best orthopedic surgeon I have ever worked with. I say that because I have had 4 other surgeons leading up to my hip replace with Dr. Gorab. He is an amazing Dr. and if I were to consider a joint replacement again, he would be the only one I would consider.

  • It's been 3 months since my total knee surgery with Dr. Gorab, and had to write about his caring and professionalism during the preparation, surgery and recovery period. He and his wonderful staff-Susie and Jackie, made sure I was prepared throughout the whole process, and that I continue to make great gains. I highly recommend Dr. Gorab and his staff.
