“She is absolutely the best ! I felt I was talking to a friend I was able to open about all my issues I have been dealing with in the past year, she gave me the motivation for me to embrace this New year with new perspectives and hope . And the best is that she will follow up which my previous psychiatrist never did it was all about refilling my meds in a 5 min consultation..She is my answered prayers!!”

“She was very kind and took her time talking to me and really listened. In my current state of mind, it’s exactly what I needed— someone to listen and care.”

Kari made me feel like there was hope after struggling with my mental health for so long

unsure. very tired of going for treatment of one of my conditions that i have diagnosis for and being addressed and handled as such only then to bring up symptoms of an existing comorbidity/condition and for that condition to be the main focus. bedside manner was fine but i felt unsatisfied with her reasoning of immediately prescribing a brand name medication for one condition when i had came in specifically looking for another specific treatment that affects my daily life more consistently and much worse.
