Theresa Guzman, Registered Dental Assistant
Theresa has been in the dental field since 2007, when she graduated from Kaplan College. She worked for Apple Dental Center right after she graduated from Kaplan and has recently returned to work for us again. Theresa graduated from Robstown High School and decided to attend Kaplan college as a dental assistant because she wanted a career that would allow her to work with people. Dr. Barwise's patients compliment Theresa most about her concern for their well being and her contagious laugh. She gets along well with her fellow employees and is always wanting to lend a hand.

We are fortunate that her paths led her back to her Apple family!
