Meet The Team

Dr. Joe

Dr. Hweejo "Joe" Byun

Dr. Byun is a Canadian certified specialist in pediatric dentistry and a fellow of the Royal College of Dentists of Canada. He recently joined Red Deer Pediatric Dentistry as a full-time partner.

Dr. Byun grew up in Seattle and completed his education and training in the United States. He attended the Johns Hopkins University in Baltimore for his bachelor's degree, and graduated with honors in three and a half years. Following his undergraduate studies, Dr. Byun attended the UCLA School of Dentistry in Los Angeles for his Doctorate in Dental Surgery, where he received the prestigious Dean’s Letter for his accomplishments in didactic and clinical training. During this time, Dr. Byun discovered his passion for working with children, which led him to pursue his specialty training in pediatric dentistry at the Yale New Haven Hospital and the Yale School of Medicine.

Dr. Byun credits his own fearful experiences as a pediatric patient, and his young-at-heart personality, with making him a compassionate doctor who can treat the most reluctant and fearful children. He seeks to create a positive dental experience for both the children and the parents in order to establish a foundation for a lifetime of stress-free dental visits.

Dr. Byun enjoys watching and playing sports, food, and traveling. Though a recent Canadian transplant, he is becoming a big NHL fan.
