Everyone is great before and while I was doing prep I called with questions and received prompt reply. I also planned for no anesthesia however the anesthesiologist made me way more comfortable with explaining the process. Dr. Oey was super amazing and the nurses are the very best!!

I had the nicest nurses and all the rest of the doctor and help. They were very friendly and helpful. They brought me a list of food to mark what I would like and I would give anyone who asked me about my same day surgery and I would have to say I had excellent care.

The nursing staff is amazing! They are personable and care about the patient. The doctor is excellent! Everyone treats you like a person, not a case #. I cannot say enough good things about this facility & staff. I am a very nervous, anxious, depressed, and shy person and they put me at ease every time.
