    She was very nice and professional and considerate of me and my condition.

    Dr. Forst was absolutely fantastic. She was super understanding and accommodating to the fact that it was a super scary time for me not knowing if my brain tumor was cancerous or not. She was absolutely fantastic. Her entire staff was wonderful. She explained stuff in a way that was easy to understand. I understood most of it from because I'm a STEM student, but she explained it in a way that my mom, who's not a STEM person, understands. And I thought that was really fantastic that not only did she address me as an adult, but she also addressed my mom as well because she's my support system. But Dr. Forst was fantastic and I couldn't speak highly of her, highly, I couldn't speak more highly of her. But yeah, she was great and her office is fantastic. Yeah.
