I have been struggling to find a provider that will actually listen and put forth an effort Into my diagnosis and medication treatment. It has been years Since I have found a provider that is willing to take their time to help me. My search ends here because Mary went above and beyond to figure out what works best for me and she listened to what I had to say While also asking appropriate screening questions because shes actually cares about my results! I would recommend Mary Nganga to anyone who wants an educated and and genuine provider. Thank you for making a difference!
I had a super experience with Mary Nganga. She listened and heard me. She was very compassionate and knowledgeable. I would recommend her to anyone.
Great first impression! Did not have to wait. Experience reinstated my confidence that superior mental health treatment does exist; treated with respect, given appropriate time & not rushed thru, ensured all questions & concerns addressed, and given a step by step plan for treatment. Glad I kept advocating for my daughter's mental health treatment and searching for the right provider fit and landed at Life Stance. Thank you Mary Nganga MA, PMHNP
