Brent Bankhead, DDS, MS Dr. Brent Bankhead, his wife, and dog
Dr. Brent Bankhead was born and raised in St. Louis, MO. He graduated with a Bachelors of Science degree in Biology from Brigham Young University in Provo, Utah. He then attended the University of Iowa College of Dentistry, where he received his Doctor of Dental Surgery degree and was awarded the Dow Research Award for three consecutive years. Following dental school, Dr. Bankhead returned to St. Louis and attended Saint Louis University for his orthodontic specialty training and completed a Masters of Science in Dentistry. While in residency, Dr. Bankhead began working for his father's practice, Bankhead and Firth Orthodontics, later becoming a partner in 1998. In the years since he joined his father in practice, Dr. Bankhead has expanded the practice to six locations, serving the O'Fallon, Wentzville, Warrenton, Chesterfield, Columbia, and Waterloo communities.

Dr. Bankhead is an international lecturer of SureSmile and SureSmile QT, and serves on the SureSmile Advisory Board. Working with SureSmile technology, Dr. Bankhead is also active in developing and implementing the latest in orthodontic technologies. He is recognized for pioneering SureSmile's "hybrid orthodontic system", a treatment system that combines traditional braces, lingual appliances, and clear aligners, especially "ProAlign", a clear aligner treatment system made by Dr. Bankhead, that is coupled with SureSmile technology. In the past, patients would have only one kind of treatment for both arches of the mouth. Now, Dr. Bankhead is pioneering the "hybrid orthodontic system" by doing different treatments on each arch. For example, a person can now have upper lingual braces, and a lower clear aligner or an upper clear aligner and lower labial braces. This hybrid system is both beneficial for treatment and cosmetic purposes. Additionally, Dr. Bankhead serves as a mentor for numerous SureSmile and SureSmile QT doctors, performs on-site training for other practices, hosts in-office courses for fellows doctors and staff, and has hosted the monthly SureSmile QT Study Club webinars since 2012.

Some of his past topics include "Phase Treatment", "Lingual (Hidden) Braces", "SureSmile Technology & Orthodontic Treatment", and "The New Age of Invisalign".

Dr. Bankhead and his wife, Laurice, have three boys, Christian, Spencer and Samuel.

Alexander Oldroyd, DMD
Alexander Oldroyd Dr. Alexander Oldroyd loves being an orthodontist, especially when his patients see their new smile for the first time. Some patients begin treatment feeling too self-conscious to smile, but when they get their braces off, they just can't stop.

Dr. Alex loves learning. He graduated with honors from Brigham Young University where he majored in physics, and to keep life interesting, earned minor degrees in music, math, and German. His favorite part about BYU was singing with the Concert Choir, where he served two years as the choir president.

After graduation, Dr. Alex returned to his Northwest roots and studied dentistry at Oregon Health and Science University in Portland. After receiving his Doctor of Dental Medicine degree with honors, Dr. Alex worked as a general dentist in Eureka, Missouri and realized the satisfaction that came from helping people improve their smiles.

Dr. Alex was accepted into an elite 3-year orthodontic training program at Albert Einstein Medical Center in Philadelphia, PA. Out of the hundreds of applicants, Dr. Alex was selected to receive one of three resident positions, which are offered only every other year. This clinically-oriented program provided him with a diverse patient base including early treatment, adolescent, and adult cases of all difficulties. Dr. Alex loved getting to know his patients and providing them with excellent care. During his residency, he was fortunate to study surgical orthodontics and orthodontic treatment of cleft lip and palate with the director of the Lancaster Cleft Lip and Palate Clinic, the oldest such clinic in the world. He is committed to continued education and is Invisalign certified.

While in Philadelphia, Dr. Alex met Martha Washington, ran the art museum steps, and discovered that although cheese steaks don't live up to the hype, water ice is Philly's best kept secret. Although he enjoyed his time in Philadelphia, Dr. Alex and his wife Alison are excited to be back in the city where they met. They live with their daughter, Alyssa, in Lake St. Louis. Dr. Alex loves museums, is actively involved in church, and likes to read, camp, cycle, eat cookies, play games with his daughter, and take his wife ballroom dancing.
