Cynthia Castro
Director of Operations

Hello everyone, my name is Cynthia Castro. I am honored to serve as Director of Operations at Sierra Dental Care (SDC) located in Modesto, CA.
I have been in the dental field since 1995. I started my dental career locally as a receptionist and quickly moved up to management. I have worked in all area’s including Pedo, Endo, Oral Surgery, General dentistry and a little in Ortho. I am familiar with all PPO and DHMO insurance plans. I take my position very seriously and I am always looking for ways to make every patient’s dental experience as pleasant as possible.
I have been married 34 years to a loving supportive husband who has worked as a conductor with BNSF for over 25 years. We have two wonderful adult children. Our first born served in the US Navy for 6 years and he is currently attending San Jose University and has an amazing wife that we adore. Our daughter and son in law had our first granddaughter. We are all overjoyed and can not get enough of her. My son in law was in the US Navy for 8 years and has started his new carrier in March of 2024 with Burlington Northern Santa Fe Railroad (BNSF) as a conductor. My hobby is spending time with my family as much as possible.
