Arash Mostaghimi, MD is a brilliant Dermatologist, which is a quality i can quickly recognize, since my father was also a brilliant Dermatologist. Dermatology requires siadnostic expertise that draws from what is visible, the patient's narrative, ruling out all other possibilities, and examination. He was respectful, attentive, took all factors of my dermatological symptomatolgy into consideration, and, upon my request, retrieved a Woods Light to rule out the top "easy" categories the had to be disqualified.He offered the standard script, if I wanted to remedy appearance, but which must be taken for the remainder of my life, to prevent a "kick back" effect. I declined, to which he added" I understand. let me know if you change your mind." He then suggested a topical treatment to ameliorate symptoms, was writing it down, but I assured him I would remember it, conveyed admiration for my capacitity to retain the information. [redacted] Arash M himself could not have been more respectful while keeping his focus on his diagnosis. The unwelcome news he had to deliver was communicated in a compassionate manner.

I've generally had very good experiences at Brigham and Women's, and especially with my usual dermatologist (who wasn't available for a visit at this time), but I left the office after this appointment feeling like I should be celebrating (what I had been concerned might be pre-cancerous I was told wasn't) but instead feeling irritated and like my trust in the medical establishment had taken a hit. It was hard for me to even trust what would have been good news, since my concern didn't seem to really register - the focus was all on my rosacea, which I've had for years, and am not concerned about. Even after asking if I had other symptoms, and saying no, and that it doesn't bother me, I was assured that I would "feel better" after using medications to fix something that isn't a problem for me.
