I cannot say enough good things about my experience with Lifestance as a healthcare provider. From start to finish, the level of care, professionalism, and attention to detail has always been exceptional. Ive felt genuinely listened to, respected, and supported throughout my experience with them. The provider takes the time to explain everything clearly, answer all of my questions thoroughly, and makes sure I am comfortable with each step of my care. This is exactly how healthcare should be delivered, I highly recommend them.

Lisa Roseberry has to be the absolute best around!! She listens and hears what you’re saying! She is the one person I trust with absolutely everything. She treats you, the person! And I know it’s weird, but I know she honestly cares about me. I have a huge medical team, and Lisa is the one who knows me best. My ADHD and Menopause is overwhelming right now, and she gets it. If you are a woman with ADHD and going through menopause, you won’t find anyone better than Lisa Roseberry!

Nyla Gardener at lifestance is my favorite person. Her understanding, personal experience and her incredible knowledge are the reason I have been able to feel "normal" while I transition from being a daughter, to not having my mother. I would not be here if it wasn't for her. I highly recommend Lifestance and would suggest anybody who is feeling down, reach out. Youre not alone and for once, someone ACTUALLY wants to help.

Great accommodations with tele health access to an abundance of providers with different specialties. Very easy to schedule and communicate with providers once an established patient. Also easy to change provider if desired. Their updated platform has made tele health visits themselves connect with better quality and ease. Sharing a positive review knowing someone could benefit.
