December 13, 2023Darien L.Verified patient
I needed to see an allergist or dermatologist for my eczema and found Dr. Leath through Zocdoc. I didn't have to wait longer than 2 minutes to be taken care of and he listened attentively and asked thorough questions. He was professional and friendly, and I felt very comfortable in his care. I also appreciated that, at least for my insurance, they didn't require a referral from my primary care physician.
