Awesome experience - honest, open, and detailed in his explanation. He responded extensively with care and attention to all my questions and concerns! His greatest asset as a human being is his complete honesty with his patients. Due to the sensitive nature of the procedure that we discussed, the doctor, even though he has experience with these types of procedures, suggested a consultation with a colleague of his who has more In-depth experience with the specific procedure that was discussed. Thank You!
