★★★★★Whole family

“My whole family has been coming here for over 10 years, always fantastic. All the staff, hygienists, dentist are great. 10/10”

Mallory Q. · Google · Jun 2026

★★★★★Dental anxiety

“I had to come in for an emergency exam. I had called three other Dentist offices near me and each one was rude and dismissive. I called here and Lonnie answered and was so kind, compassionate and genuinely seemed like she cared and wanted to help me. … Every other person that I came into contact with were very nice and wanted me to be comfortable and at ease. I definitely recommend if you are like me and have strong anxiety surrounding the dentist.”

★★★★★Cleaning & exam

“My usual dental hygienist was unable to care for me today. Irini was able to fit me in and she was great! She was so nice! I would highly recommend her or Diedre. Dr. Diaz was, also, very nice. Highly recommend this dental office.”

“Everybody knows everybody. We don’t have to look in the notes.” Dr. John Altomare, on the team and the patients.

Dr. John Altomare

DMD · Tufts University School of Dental Medicine · Owner

Dr. Altomare has been practicing dentistry in Winter Park since 1990. He coached local youth football and baseball for years, and now treats the kids of former players’ kids.

He does almost everything here in the office, from full braces to implants, because he’d rather do it right than send you somewhere else.

Dr. Christian Concepcion Diaz

DMD · General & restorative dentistry · English & Spanish

Dr. Concepcion Diaz grew up in Cuba and went to dental school there, then came to the US, redid dental school in New Jersey, and graduated in May 2026. He sees patients in English and Spanish.

He chose dentistry because it combines science, artistry, and a fair amount of comedy.
