Meet our Team

founder, D.D.S.

Christopher E. Wacker, D.D.S

Dr. Chris Wacker has owned Loma Linda Children’s Dental Group since 1997. His philosophy is to provide extraordinary oral healthcare to children in a trusting and educational environment, which focuses on prevention and treatment of tooth decay.

Born in Michigan, Dr. Wacker moved to California when he was a teenager. He graduated from Loma Linda Academy and completed his dental pre-requisites at Cal State San Bernardino and Pacific Union College. He then graduated from Loma Linda University School of Dentistry with his Doctor of Dental Surgery degree. Dr. Wacker followed his passion for treating children by completing a two year Pediatric Dental Residency at Loma Linda University School of Dentistry.

Dr. Wacker is a strong believer in continuing education, and primarily focuses on caries (tooth decay) prevention in his practice. He finds it most rewarding to educate patients and their families on how to prevent tooth decay so the entire family can enjoy a lifetime of oral health.

Besides Pediatric Dentistry, Dr. Wacker is also passionate about his family – wife Leanna, and daughters Danica and Makena, off-road racing, cooking, and living life to its fullest!

Steven Kirby, D.D.S.

Dr. Steven Kirby is a pediatric dentist. He grew up in rural northern California in the town of McKinleyville. At the age of 19, he went on a two-year service mission for his church in Santiago, Chile where he learned a new language and culture. He is fluent in Spanish and continues to be in contact with friends that he met while in Chile. Upon his return to the United States, Dr. Kirby moved to the sunny end of California and received his Bachelor’s degree in Chemistry from the University of California Riverside. Dr. Kirby was then accepted to the Herman Ostrow School of Dentistry of USC where he served as co-student director for one of the dental outreach programs. In that capacity he organized and participated in over 50 clinics that took place California, Mexico, Belize, Guatemala, and Colombia. Following completion of his Doctorate of Dental Surgery from USC, Dr. Kirby completed a two-year hospital-based pediatric dental residency at Doernbecher Children’s Hospital in Portland, Oregon.

Dr. Kirby is very passionate about teaching parents the importance of good oral hygiene practices for their children from the time their child’s first tooth erupts. He also stresses the importance of finding a dental home where the pediatric patient is seen on a bi-annual basis. This practice will help reinforce the oral hygiene instructions that are given and will allow for the early detection of caries. Dr. Kirby has a very calm and cool demeanor that helps relax both his pediatric patients and their parents. He feels that making visits to the dentist a fun and enjoyable experience for his pediatric patients is one of his most important jobs. This willingness to come in for regular checkups and receive any treatment needed will foster a good life long relationship with the dentist. Dr. Kirby loves spending time and vacationing with his beautiful wife, who is a Prosthodontist. They met at dental outreach program during dental school and have been together ever since. They are very pleased to have a new member of their family in their baby girl, Kaia. Dr. Kirby is an avid motorsports fan and enjoys watching and playing basketball, baseball, football, and motocross. He also enjoys working on classic cars.

we are here for you

Emergencies 24/7/365

Emergency care is always a priority.  We hope that your child will never experience a dental emergency, but if it happens, we want you to know what to do.  We have an on-call doctor 24 hours/seven days/week for emergency situations for patients of record.

Call Loma Linda Children’s Dental Group office immediately for any trauma to your child’s teeth or jaw.  If your child’s teeth are broken or knocked out, put them in milk or your child’s own saliva. Avoid rinsing the teeth with water or wiping/scrubbing the teeth.

In the rare event in which you do not hear from us, please call Loma Linda University School of Dentistry Pediatric Clinic at (909) 558-4689 and you will be connected to the Emergency Room where a pediatric dental resident can help.
