Dr. Perezouse has been my doctor for over 10 years I have no complaints of his work and how he treats me patients and a person . he knows his stuff and does the best he can
Dr Perezous was thorough, compassionate and took his time with me. I was hesitant about having my knee aspirated but he explained the process well and I feel so much better since having it done.

No nonsense Dr. everything well explained. Thank you!
Very friendly and really knows his medical
Absolutely love Dr Perezous. He has done a total of 4 knee repairs for me in the past. He is the only one I trust for my knees. Totally sad he doesn't do knee replacements. But trust him when he recommend another specialist for hip and knee replacements.
