Dr. Alice Chen
Associate Professor, Pediatric Dentist

Dr. Alice Chen joined Roseman’s College of Dental Medicine in 2022. With a warm smile, kind face and gentle way, it is obvious that she has a gift for connecting with children. Born to parents who guided her toward a professional ethos, “be helpful and take care of others,” Dr. Chen has followed this guidance many times over.

After a decade in private practice, in 2021, Dr. Chen decided to focus more time on the practice of pediatric dentistry and part with the administrative and business tasks associated with running a practice. The opportunity at Roseman Dental & Orthodontics was a perfect fit. “Joining Roseman allowed me to focus more on doing what I love most—treating children. I couldn’t be happier about the opportunity to focus on children while training dentists to be caring and competent providers.” In her role in an academic dental practice, Dr. Chen has the chance to shape and inspire dentists in training through Roseman’s AEGD residency program.

Dr. Chen practices at Roseman Dental & Orthodontics in Henderson and at Roseman Dental – Summerlin, Roseman’s pediatric dental clinic focused on treating medically compromised children in need of specialized dental care. Dr. Chen works alongside Dr. Matthew Thacker, Clinic Director, to treat patients of Roseman’s partner organization, Cure 4 The Kids (C4K). C4K treats children with cancers, blood diseases, and other life-threatening diseases. These children often put their dental needs aside, in need of a dental home that can deliver what is often specialized care.

Dr. Chen is a diplomat of the American Board of Pediatric Dentistry and a fellow of the American Academy of Pediatric Dentistry. Dr. Chen is an advocate for HPV prevention, serving on the American Cancer Society’s National HPV Vaccination Roundtable’s dental task group charged with updating ACA dental action guidelines. She lectures on behalf of the Nevada Cancer Coalition, the AAPD, the Nevada Department of Health and Human Services, and Roseman’s Neighborhood Health Series. She is a CCSD volunteer dentist, an evaluator for the NV State Board of Dental Examiners, serves as Board Secretary for the NV Association of Pediatric Dentistry, and is Board Treasurer for the National Charity League.

Dr. Chen received her bachelor’s degree in psychology from UCLA with an emphasis on developmental psychology, graduated cum laude from Boston University, and pursued her specialty degree in pediatric dentistry at Temple University Hospital. She is married to Dr. Matthew Raddue.
