    I really like the attention he pays to me and my health including not being rushed and explaining what he's doing (e.g. ""this is the part of the appointment when I need to enter things on the computer"" or something to that effect).

    He asked a lot of questions about my life, symptoms, history of disease, my hobbies, travel, environment within and outside the house. He suggested a treatment plan, did not seem concerned about the stage of my illness, which was reassuring. He provided ways to get in touch with him and when to use him vs family doc.

    Dr. Ladd is, without a doubt, the best doctor I've had in my life. I've been through a long and difficult medical journey, and no provider has ever come close to the level of care, attentiveness, and reliability that Dr. Ladd and his team offer. He listens, truly cares, and always follows through in a timely way. For the first time, I feel like I have a medical team I can count on.
