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!

A few adjustments were made to my wellness plan and I feel better than I have in years! From sleep to work productivity and even my communication skills as someone with inattentive ADHD who fights chronic fatigue. Mary Nganga listens. She is very supportive of me as a patient and has a wonderful spirit. I have found my Psychiatric NP for as long as she is practicing. I encourage you to see for yourself.

I have had nothing but a wonderful experience with LifeStance. There was a complicated start due to a mixup with Zocdoc, but they help me smooth it out and immediately jumped to help me. I am very grateful for Jeanette and Mary and looking forward to continuing care with them.
