I am a new patient of Mareena Miller. She is very attentive and relates well to my health concerns. Her ability to immediately make you feel comfortable was extremely helpful for me as a new patient. She takes the descriptions I rShow moreelate and easily breaks them down into her professional knowledge base in order to assess the best plan for dealing with that issue. I have full confidence in her and look forward to her continuing input for my mental health.

Dr. Miller has been very informative and helpful during my visits. She actually provided overall health advice and life changes instead of just asking a general question. I appreciate her knowledge and expertise. As a “fitness gurShow moreu” It’s nice to have a doctor that is also a health enthusiast and practices healthy habits. Thank you!

Wendy A • June 08, 2026

Provider did not order my medications/refills as she had stated she would. Provider was upset with me for getting my labs checked late but when I went to labcorp, no tests had ever been ordered. Spends time during appointment talking about herself and children/husband instead of talking about how I am doing.
