What Our Patients Are Saying

Average Star Rating:
5/5
We had an amazing experience with this surgery center! Our 20 month old had to have hernia surgery and we were so impressed with everyone that we interacted with at this facility. From the receptionists, to the nurses and doctors, everyone was warm and welcoming. Would highly recommend.
Thank you Dr. Nic Allen! Best Dr appointment I have had ever. Everything was nice paced so I wasn't sitting waiting forever. The Dr Allen was professional and fun. I'm feeling way better already and haven't even started treatment. Love this place! The entire staff was great!
Dr. Fairfax was amazing she listened to me most importantly!! I feel so much better having her as my new urologist in fact she will be doing my surgery and I know I am in GOOD hands. I recommend her as a urologist she has great bedside manner, she is informative and kind.
Everyone there has a smile and they always make it a pleasant experience. Dr. Petrillo is patient and listens and talks to you not at you. There is a very big difference I recommend this office without reservations.
Been going here for a number of years now and have always been treated well both by reception, nurses and Dr. Williams. I saw Dr. Williams personally escorting people in the icy parking lot into the office so they wouldn't slip and fall. I've never seen a doctor take charge like that to ensure patient safety. Very satisfied.
Dr. Parrillo is one of the best doctors I have ever seen! She is super nice, makes me feel well cared for, and always has my best interest at heart! Highly recommend!

August 15, 2025

A vasectomy is a common and highly effective form of male contraception.
