Dr.   Michelle  Stafford

Dr. Michelle Stafford founded World of Smiles, Pediatric Dentistry in August 2008. After graduating University of the Pacific: Arthur Dugoni School of Dentistry, Dr. Stafford chose the pediatric dental specialty because she believes that every child deserves to have a positive experience going to the dentist.

 

She completed an additional two years of training after dental school in an accredited pediatric residency program to become a pediatric dental specialist. Throughout this two year program she cared for children of all ages and especially children with special needs such as: autism, cerebral palsy and cleft lip/palate. This hospital-based  residency provided a safe environment to treat the dental needs of children under general anesthesia, conscious sedation and/or nitrous oxide.

Dr. Stafford is also very passionate about tongue and lip ties. After experiencing the effects of of a severe tongue tie with her first baby, she was unhappy with the traditional treatment options, so she sought more education on the issue to be able to offer the laser procedure to release tongue and lip ties in office. Learn more about tongue tie here.

Dr. Stafford enjoys hiking, crafty projects like sewing and scrap-booking and exploring the Portland area with her husband, Nicholas Peterka. They welcomed their first child on June 1st, 2012. Wasting no time, her second son came along on April 21st, 2014. Some of her other hobbies include photography, traveling and learning about different cultures. She has incorporated her love of travel into World of Smiles. The West office interior serves as a gallery for artwork and photography from around the world.

Dr. E. Chioma Onwuka recently moved to Portland, Oregon and is thrilled to be part of the World of Smiles treatment team. Dr. Chioma is a board-certified pediatric dentist. She received her Bachelor of Science degree in Biological Sciences from Stanford University in 2006 and her Doctor of Dental Surgery degree from the University of California, Los Angeles in 2010. While at UCLA, she held leadership positions in the student chapter of the American Academy of Pediatric Dentistry and received the Excellence in Pediatric Dentistry award by the Southern California Society of Dentistry for Children.

 

Following her time at UCLA, she completed two additional years of specialty training in pediatric dentistry at the University of Washington. Her pediatric dental training was based full time at two community clinics in Yakima, Washington. In Yakima, there is a great need for pediatric dental care and her program provided a unique training experience as she gained a very high level of clinical exposure treating children and adolescents of all ages. After residency, she spent several years working as an associate dentist in the greater Los Angeles area.

 

As a pediatric dentist, Dr. Chioma values preventive dentistry as the core of her practice philosophy. For this reason, she strives to build strong relationships with her patients and their families in order to provide adequate oral health education and in turn quality, comprehensive dental care.

Dr. Chioma was born and raised in Southern California, but she is excited to be back in the Pacific Northwest serving the dental needs of the children in the area.  In her free time, she enjoys hiking, watching movies, and spending time with her loved ones, including her boyfriend, Chidi.
