Patient Testimonials

  • "This practice is all about the patient. The staff is professional, they do not book multiple overlapping appointments as they understand the importance of and respect peoples time. This is all great but the real reason you need to come is the Doctors - they know what they are talking about. I was prescribed only what I needed and actually was talked out of buying all the products I THOUGHT I needed. You will not be disappointed!" -Lia H.   

  • "I have been seeing Dr. Cassandra for a year or so. Their office is exceptionally clean. The staff is professional and it's a calming atmosphere. And there is no wait time to be seen. Dr. Cassandra is very professional and caring. She makes sure you understand her diagnosis and treatment plans. I recommend Signature Dermatology to my friends and family." -Patti S.
