What Patients Are Saying About Our Staff
Leah McWhinnie
Local Guide Level 4
I can not say enough nice things about Dr Nguyen and his entire staff. Dr Nguyen provided such personal care and I didn’t feel like a patient, I felt like family. The location is beautiful, calming and relaxing. Everyone, from the front desk to the PA was professional and engaging. I wish I could give them 100 stars!
Lisa White
Professional, friendly, efficient team. They take their time being sure you know exactly what they’re doing, taking care to treat all procedures as painlessly as possible. Very thankful we were referred there by our normal dermatologist for skin cancer treatment.
Stavianeq Walker
Words can't even begin to describe how grateful I am to have found a team that has educated themselves and are continuing to educated to understand my skin condition! I felt so welcome from the time I stepped into the office. Definitely worth the 3 1/2 hour drive. Thank you all so much

Dr. Nguyen and his entire team are absolutely SUPERB!. From check-in to check-out, every staff member—his MAs, and front desk team—is courteous, respectful, and genuinely friendly. His PA is highly knowledgeable, and Dr. Nguyen himself has an excellent personality, impressive clinical knowledge, and outstanding communication skills. I highly recommend Dr. Nguyen—and this endorsement comes from a “physician himself”!
