Dr Miller is great, She is very understanding and able to work with my abnormal work schedule to help ensure I’m able to make my appointments. If you’re looking for a new provider I would highly recommend her.

I did not enjoy the computer talking back-and-forth to each other.I have appointment to face your face.I never want to experience it again over the computer

Cecil P • August 27, 2026

She is always on top of everything; remembers my medication and the issues we talked about; she is great one-on-one and always follows through

Wendy A • August 26, 2026

At times, Mareena is in too much of a hurry. She does not listen to your needs, and she is unempathetic. She prescribes the same mediction over and over again without your input if it is really functioning. She definitely needs to listen more attentively, have a more caring prescence, and she could use coaching on how to listen (and not talk over patients). She tends to not care about you.

Sheree S • August 21, 2026

Very personable, polite, she seemed to hear my concerns and answered my questions. She also provided some suggestions and ideas to help me better manage my anxiety and depression.

Edward L • August 18, 2026

Joseph R • August 09, 2026

Was very pleasant & comfortable and she is great with actually having a conversation with you about how you are doing not just a Q & A.

Scott P • August 05, 2026

I did that I have a visual on her. It really upset me. I talking to a TV screen that I don’t see nobody she did give me good advice and change my medicine but not happy with your appointment. I told her I was really frustrated with the appointment because I could not see her. She could see me, but I can’t see her very unhappy with that.
