Wonderful office

July 27, 2020 5:55 PM

The provider was very professional and answered any questions I had.

July 27, 2020 5:55 PM

I appreciate the fact that the appointment was on time, and there was not a long waiting period as in some doctor offices!

July 27, 2020 6:06 AM

Excellent, listened, explained everything.

July 22, 2020 11:19 AM

Excellent doctor, excellent nurse before doctor came in.

July 22, 2020 11:19 AM

Doctors should make more money & investment bankers less!

July 20, 2020 1:40 PM

I felt very Rush when I had concerns about my Health in order to have children later on. I feel unheard and pushed into getting on birth control and some kind of steroid to help with acne but nothing was explained on side effects. I'm tired of providers not listening and just putting me on birth control to fix the issue. any other health concerns I had she told me I need to consult other people because she wasn't in the profession to answer other health related questions. however my questions could have been related to the health concerns of OBGYN. She seemed very irritable and dismissive of my health concerns. she explained she wasn't prepared to answer my questions and that next time stress for someone to write them down before hand.

Dr. Nikolas is a wondering physician. She is caring and very thoughtful in composing her plans of care and explaining her proposal to her patients. I was impressed with not only the pleasant visit interaction but also the after visit follow-up with phone calls either by herself or her staff. Her front desk staff are also equally excellent. Ms. X in particular I have found to be extremely helpful. Finally, RN X was very welcoming and has an excellent bedside manner. I have recommended other patients to this office after my personal experience which overall was phenomenal.

July 13, 2020 8:14 AM

June 29, 2020 6:28 PM

Good, takes time for Questions. You dont feel rushed.

June 24, 2020 6:16 AM

This office is so well managed, it is always a good experience.

June 2, 2020 10:37 AM

I was really shocked at how little regard this office had for social distancing. No-one was trying to stay 6 feet apart, or even making it possible for me to do so when I tried. Also, this was not really something that needed to be taken care of immediately. They did not want to renew my birth control prescription, so they went ahead and had me come in despite the quarantine. I think they could have just renewed it and scheduled the appointment for after the stay-at-home order is lifted. I don't see how this appointment was more "essential" than the work I do as a teacher, and I'm not allowed to meet with my students in person.
