Patient Reviews

I have been coming to this office for several years. The Dr. Koumas and hi staff are always professional, friendly and efficient. Would definitely recommend his business.
-Debra 8/1/2020

The office is very efficient and well run with friendly, knowledgeable staff. My technician was very adept, thorough and concerned not just about my oral health but took care to see I was comfortable and at ease. Certainly Dr. Koumas is a proficient dentist who ensured my diagnosis was accurate and further recommended options for which I had posed questions. The emphasis on a quality patient experience makes going to the dentist, while not a ‘Disney’ event a more pleasant necessity when surrounded by professionals who exhibit care and talent.
