Testimonials
I have been a patient of Dr. Masonis since 2012. Since that time, I have had both hips replaced. Each surgery was extremely successful. Dr. Masonis is a terrific surgeon that is knowledgeable that takes the time to explain procedures to his patients. I couldn't ask for a better orthopedic surgeon. The surgeries have increased my quality of life. Thanks, Doc!!
