“My first conversation with Dr. Ash lasted an hour and I was struck by the degree of thoughtfulness that he brought to it. He is not only extremely knowledgeable about medicine, he deeply understands the challenges that patients face in the medical system and he provides all kinds of avenues to counteract that. He is knowledgeable about working both within and outside of insurance systems, which truly sets him apart. When I sent Dr. Ash my medical history, it turned out to be 300 pages, and never in a million years did I think he would read all 300 pages, ask me specific questions, and provide structured feedback—which he did. He is extremely timely in communication as well as extremely supportive. When you are used to being treated like a faceless number in the medical system, it is incredible to connect with someone like Dr. Ash and see what medicine can be like. You don’t actually have to dread going to the doctor! With Dr. Ash, you can even look forward to it.”
