After completing dental school in Canada, he moved to California to practice general dentistry and soon found his passion working with kids. Dr. Opinga is a general dentist who limits his practice to children. He has over 12 years of experience providing general dentistry for children in over 18 dental offices all over Central and Northern California.

 

Dr. Opinga has a very strong passion and love for treating children in their dental needs. His experience, training and love for children enable him to put together an honest and proper treatment plan that is essential in gaining the trust of his patients and their parents.

In his life outside of dentistry, Dr. Opinga is a believer of Jesus Christ and loves to travel and spend time with his wife, Joyce, and their three kids, Jaden, Justine, and Jillian.

Dr. Andrew A. Rivamonte is a general dentist who graduated from the University of Michigan School of Dentistry in 2009 with a doctor of dental surgery degree. He completed a general practice residency at the University of Michigan Hospital, Department of Oral and Maxillofacial Surgery and Hospital Dentistry where he treated medically compromised and special needs patients. Dr. Rivamonte is an active member of the American Dental Association, California Dental Association and Contra Costa Dental Society.


Dr. Rivamonte accepted a position at Bethel Kids Dental after realizing the need for dentists in the younger population who tend to have difficulty in access to dental care.
 

He enjoys spending time with his family, traveling, collecting baseball cards, and watching sports. 

Dr. Pauline Lim was born and raised in the Bay Area, CA. After completing her Bachelor’s degree in Molecular Cell Biology with an emphasis in cell development at UC Berkeley, she went on to obtain her Doctor of Dental Surgery degree at the University of Michigan School of Dentistry. She also completed a general practice residency at the Veterans Affairs Hospital in Ann Arbor, MI with dual hospital privileges at the University of Michigan Hospital treating medically complex and compromised patients. 

 

After too many snowy winters in the Midwest, Dr. Lim was ready to come back home to CA, where as a general dentist, she has been practicing general dentistry for adults and children for the past 10 years. With her passion and joy in working with children and adolescents, she now wants to focus on them to emphasize the importance of early prevention and the education of childhood cavities. Her goal is to develop and build positive experiences and behaviors that will lead to good life long oral health practices for each of her patients. 

 

Dr Lim is a member of the American Dental Association, California Dental Association and Contra Costa Dental Society.
