K2 Dermatology (formerly Kallgren Dermatology) was recommended to me by my primary care physician. I have a high opinion of this practice, insomuch as a layman can judge. I never have to wait; they are always very courteous and professional. My practitioner never hesitates to use the liquid nitrogen spray on my small problems, which I think is a good thing.
