I just moved here from Colorado and was very close with my specialist back home. I was very worried I would get lost in the mix of doctors in such a big city. But, GDO made me feel right at home with their services, friendly staff, confidence, and the overall welcome I received. I would definitely recommend GDO for any complex orthopaedic and/or oncologic issues you have. Sarah J.
I first saw Dr. Mollabashy a few years back for an osteosarcoma in my right femur, after being passed back and forth between several other physicians. He not only gave me a diagnosis, but also explained my options and treatment plan. I immediately felt at ease. He was very meticulous and took his time reviewing my complicated case. The GDO team is altogether very helpful and accommodating. None of the other doctors I have seen in the past have matched Dr. Mollabashy’ s compassion or attention to detail. I highly recommend him.

I had left hip surgery with Dr. Al Mollabashy on 8/1/2016. From the initial consultation to the post op follow up I was very impressed with him and his staff. He took time to sit and speak with me and explain the hip surgery. I was so scared to have the surgery, but after meeting with Dr. Mollabashy he eased my mind and I was ready to have the surgery done on my left hip. I feel like people only write reviews when it’s a bad experience but my experience overall was not bad at all. I would highly recommend Dr. Mollabashy. Thank you for changing my life for the best.

I was in an accident and saw Dr. Abbaschian as a trauma patient. He has operated on me 3 times total and I really feel like he took great care of me. During such a difficult time, it was comforting to know that I felt like my surgeon was really concerned about me and getting my life back to normal. He has great bedside manner and has always made me feel like I am getting the best possible treatment. Patricia W.
Dr. Gilbert saved my life! After seeing multiple physicians and being referred out every time, Dr. Gilbert knew exactly what was going on with me after my very first appointment. He set up a biopsy of a tumor on my pelvis for the very next day to confirm his suspicions and I was able to start treatment shortly after. I cannot express how much I appreciate everything that he did for me. He is an amazing surgeon who I will be forever grateful for. I am finally on the road to recovery! Sandra K.
Dr. Abbaschian and his office are the best I’ve gotten treatment from in a long time. The doctor is very busy, but took the time to make me feel like I was the only patient there. After receiving my cancer diagnosis of a sarcoma in my thigh, he was extremely attentive and thorough in making sure I understood my condition. From the front desk to the surgery scheduler, Dr. Abbaschian’ s team is top notch. I would definitely recommend him to my family and friends. Kelly S.
Dr. Gilbert went into great detail explaining surgical options for my recurrent total knee infection. I felt comfortable knowing that he knew what was best for me, as this had been my 5th surgery trying to save my leg. I had gotten very discouraged seeing other physicians and Dr. Gilbert seemed to have much more experience and success with my condition. Now I am able to enjoy spending time with my kids, go out for walks, and enjoy daily activities. HE IS THE BEST! Andrea Q.
