Dr. Mousa Matar is a great doctor. He is very kind, caring, and really takes the time to listen to all my concerns. He explains everything clearly and makes sure understand my options and test results. You can tell he truly cares about his patients and always goes the extra mile. He is very knowledgeable, experienced, and professional, and I feel comfortable having him as my primary doctor. His staff is also very friendly and helpful. I highly recommend him!

After 6 months of having numerous appointments I never met the doctor. His pa was very helpful but he was not. Only talked to him by phone when I needed a Perscription refilled and he had not allowed. He farms a patient out to other doctors. Pain management, Urology etc. He had took over from my previous Dr Kane who retired December 31, 2024. He stated by phone he wasn't prepared for the 3 times the work by taking over another practice. The last straw was when he told the receptionist that I should see a psychiatrist after repeatedly calling trying to get a PERSCRIPTION refilled for over a week.
