D. Torres SAGA Patient

The nurses were the best. And the tech that did my IV had such a good hand that I didn’t even feel it when the needle went in. They all listen to you. They’re just so kind hearted. And the Dr that did the procedure was so kind also he made me feel so relaxed. The only thing I missed was the music they used to put on back 10 years ago. I almost forgot the Dr that put me to sleep she was so sweet I thank you so very much.

R. Soto SAGA Patient

While I’ve only met Dr.Otero briefly prior to a procedure, I’ve had a few office visits with Ms. Reygoza. While I would rather not be going to the doctor in the first place, she makes every visit as informative, pleasant, efficient, and quick as possible. I appreciate her genuine concern and patience when answering my questions to put me at ease, because most likely I’m in the office for something unpleasant or worrisome. At my most recent office appointment she took a few extra moments to offer some words of wisdom that she really didn’t have to take the time to do and I don’t think she knows how much I appreciate her concern.

I would like to commend the staff at SAGEC North for their exemplary demeanor with their patients. I am a returning patient for the colonoscopy procedure with Dr. Joseph Johnson, this being my 4th procedure, performed early this morning (11-30-16). The entire staff is warm and friendly toward each patient, placing the patient at ease and made to feel welcome. Their personal interaction with the patient is very much appreciated. Dr. Joe Johnson is, in a word, wonderful, and an expert in his field. Thank you very much.

Carolyn SAGA Patient

Just a note to commend the entire staff who tended my needs last Friday morning! From my arrival time at 6:15 until my discharge at 8:35, I truly had a wonderful experience. Everyone was friendly, professional, caring, considerate, and very kind! The entire facility was run like clock-work yet never did I feel like just a number!! Thank you ever so much to each and all.
