Dr. Jason K. Tam

meet dr tam Dr. Jason K. Tam, your Unionville Orthodontist, was born and raised in Toronto and lived in Markham before moving to Richmond Hill.  A chinese Orthodontist, fluent in both english and cantonese, he is your Toronto Invisalign Orthodontist with a large case volume of experience.  As one of the most highly respected doctors in Canada with an Invisalign Teen Provider designation, he teaches Invisalign internationally to dentists and orthodontists, and has lectured to the dental hygiene students and hygienists at George Brown College.

Dr. Tam is familiar with the Univeristy of Toronto environment, having attended high school at the University of Toronto Schools (UTS) where he established the MCO Orthodontics UTS Community Builder Award and interviews prospective students, completing his Bachelor of Science with High Distinction, and followed by the Doctor of Dental Surgery Program with Honours.

During his dental training, Dr. Tam was extremely active on campus as a residence don for four years. He received several honours as the dental school president and valedictorian. He was also awarded the Canadian Dental Association President's Award, was inducted into the prestigious Omicron Kappa Upsilon Dental Honour Society, received the Xi Psi Phi Dental Fraternity Award, as well as the J.G. Bourassa Cup as the most outstanding member of the graduating class.

Following thirteen years in the U of T system, Dr. Tam decided to venture outside of Canada as a general dentist at the New York Hospital Medical Centre of Queens, part of Cornell's Weill Medical College. There he provided care to many patients with special needs and worked closely with oral surgeons on several operating room cases. He also spent one month providing dental care to Canada's native people in small communities in Nunavut.

After a year in New York, Dr. Tam moved to Boston for the orthodontic residency program at Boston University. He feels extremely fortunate to have studied under the tutleage of the late, Dr. Anthony Gianelly, the founder of the bidimensional orthodontic technique. During his residency, Dr. Tam worked extensively with and was certified in Invisalign®, the placement and use of orthodontic mini-implants, and extremely complicated malocclusions, including patients who require orthognathic surgery in conjunction with orthodontics. He completed his American Boards and is fully eligible to practice orthodontics in the United States.

Realizing what was truly important to him, Dr. Tam decided to return to the GTA for his family and friends. After successfully completing the two-day examination, he was admitted as a Fellow in the Royal College of Dentists of Canada, certifying him as an orthodontic specialist for children and adults. Dr. Tam feels grateful to be able to give back to the local community and sponsors a number of sports teams such as the Markham Waxers, Stouffville Clippers,Unionville Minor Softball Association, Unionville Skating Club, Whitchurch-Stouffville Soccer Club, Oshawa Kicks Soccer Club, and Markham Bears Ringette. He also supports the CCYAA, Markham Food Bank, Stouffville Christian School, The Rotary Club of Uxbridge, Oshawa Food Bank, Stouffville Foodbank, and Markham Stouffville Hospital.

dr. mariam harounDr. Mariam N. Haroun was born in Egypt and raised in Miami, Florida before moving to Toronto. Fluent in both English and Arabic, she received a Bachelor of Science degree with honours and a Doctor of Dental Medicine (DMD) degree from Nova Southeastern University in Fort Lauderdale, Florida. Dr. H graduated first in her dental school class and went on to receive two additional years of specialty training in the field of Orthodontics at Louisiana State University in New Orleans, LA. At LSU, she worked extensively with complicated malocclusions including cleft lip/palate patients and those who require orthognathic surgery in conjuction with orthodontics. She completed her American Boards then returned to practice in the Miami/Fort Lauderdale area.

Dr. H is extremely happy to have married the love of her life, George, who was her dental school classmate in Florida. He somehow convinced her to leave the warm, sunny beaches of Florida to relocate to Toronto, her husband's hometown, where he is a practicing dentist, and has developed a real love for Canada! Having worked as an orthodontist in America, she was still required to complete a two-day examination, and was successfully admitted as a Fellow in the Royal College of Dentists of Canada, certifying her as an orthodontic specialist for children and adults.

In their leisure time, Dr. H and her husband enjoy traveling the world as well as exploring the local parks and hiking trails with their young german shepherd, Athena. From their time in Louisiana, the young couple developed a love for po-boys, sno-balls, beignets, crawfish boils, jazz, and heretically Saints/Tigers football! You'll always find Dr. Haroun and her husband playing soccer on the weekends in several church/community leagues around the GTA.
