Meet The Staff

Violeta Guevara

Office Manager

I met Dr. Chicchon over 10 years ago and he immediately showed me the business aspect of dentistry. I have always enjoyed working with patients and helping them achieve their smile goals. I am very active in my continuing education in order to provide the best service for each patient. Being a part of this family has help me grow and be more independent in my professional and personal life.

Estela Fernandez
Registered Dental Assistant and Coordinator

I met Dr. Chicchon in 2001 when I was his patient. He made me feel so comfortable and showed me what dentistry was all about and how I could make it a great career. I decided to take the courses and get license to be a Registered Dental Assistant. Since then I started working with Dr. Chicchon and now am a part of this great family.

Dental Assistant

I never thought I would be working in dentistry. I met Dr. Chicchon about 14 years ago. He would always tell me how nice is was to work in a medical or dental office, He knew I love to help people and like to learn new things. So he changed my life by giving me the opportunity to work with him. I have been working with him since 2010, and I love my work!
