    I have complete confidence in Dr Barmettler and am extremely satisfied. She was responsive and helpful, and developed a clear strategy to deal with my issues. While initially I could not arrange an in-person appointment for seven months, within days her office called to set up a virtual and I was able to have my problems attended to.

    After seven years of going from one allergist to another and being on prednisone for seven years, I met with Dr. Bartmettler a few years ago. And instantly, she was able to figure out what was wrong with me. She was aware of the cutting edge prescription strength stuff that I could have, especially Dupixent. And in two days from the date of my first injections, my entire life changed. no more prednisone, no more scarring on my face. I am so grateful for Dr. Bartmettler. She heard me, she understood what I needed, and she treated me with the utmost respect.

    I was seen on time and Dr Barmettler spent adequate time discussing my care. She was familiar with my history and had read my medical record pertinent to my immunological issues. I am grateful to be in Dr Barmettler's care, having been referred by my recently retired immunologist. I feel that I am in incredibly capable hands.
