"Dr. Callaghan was very patient and answered all my questions before he started the Mohs procedure. Following the surgery he presented a couple of options regarding the skin repair and gave me the option to chose. This was the 3rd Mohs procedure on my face and I felt most informed with Dr. Callaghan. Also worth noting is his assistant Ashley. She gave the initial anesthesia to numb the nose. This is a very sensitive area and I was dreading this. Ashley knew how to prepare me and deliver it in the most comfortable way possible. I highly recommend this team!"
