My name is Angelica Lopez or Angie for short.  I was born in Los Angeles but raised right here in Calaveras County.  I enjoy baking, running, and relaxing with a good book or movie.  I have been an RDA since 2013 and have enjoyed meeting new patients from all walks of life.  My priority in the dental field is to provide a comfortable and pleasant experience for the patient.  Since  September 23, 2023 I have been attending a weekend program at the University of the Pacific in San Francisco to further my license and become an RDAEF2.

Andrea Fine

Front Office Assistant

Andrea is our front office assistant. She joined the team back in 2016. Andrea grew up in the Bay Area and moved to Murphys in 2003.  Soon after she and her family became patients of Dr. O'Connor's.  Andrea and her husband Matt have 5 children: Christian, Brendan, Dominick, Anthony, and Gabriella.  The Fine's are also blessed with a granddaughter, Isabela.  With no dental background, as a patient she heard about the job opportunity and jumped on it.  She had no idea she would learn so much and get to know and care for many patients.  Andrea is excited to now work with Dr. Crowley and continue to grow in her position.  She feels blessed to be a part of such a great team that feels a lot like family.  Andrea enjoys boating, cooking, entertaining, and spending time with family and friends.  She is happiest when all of her kids are home together, which does not happen nearly as much as she would like, as her 2 oldest sons are in the Military.
