Joseph A. Vaughn

Doctor of Dental Surgery and Orthodontic Specialist

Dr. Vaughn was born and raised in south Texas and is one of four children. Growing up his mother was a schoolteacher and his father worked on offshore oil rigs. He played high school football, participated in 4H and FFA, and worked in the oil fields during the summer. Mentored by his grandfather, a passionate dentist, Dr. Vaughn knew he wanted to enter the dental field at an early age.

After graduating from Sul Ross University with a master’s in biology he went on to attend the top dental school in Texas, UTHealth Science Center in Houston. After graduating in the top of his class and becoming a board-certified dentist, he was accepted into Seton Hill University’s Orthodontics and Dentofacial Orthopedics Residency Program where he completed a rigorous 2.5 years of training to become an Orthodontic Specialist. He was then honored to join an elite group of orthodontists to receive his board certification from the American Board of Orthodontics.

In his free time, he enjoys spending time with his wife, Lindsay, and young son, Finley. Some of his hobbies include spear fishing, scuba diving, and bike riding.


Gerald W. Spencer

Dr. Spencer has been setting the highest standards of excellence in orthodontics for more than 30 years and uses the most advanced techniques available today. An Oklahoma native, Dr. Spencer earned his undergraduate degree from Oklahoma State University (Dean’s Honor Roll) before earning his dental degree from the University of Missouri at Kansas City. He then continued his education by completing a specialized residency in orthodontics, also at UMKC.

Through his advanced training and testing, Dr. Spencer is board certified and is a Diplomate of the American Board of Orthodontics, a distinction held by less than 25% of practicing orthodontists. He has completed specialized courses to become certified by the American Board of Pain Management and has published articles in peer-reviewed orthodontic journals. Dr. Spencer is also a member in other leading orthodontic organizations including the American Association of Orthodontists, and the American Association of Functional Orthodontics. In recognition of his experience and judgment, Dr. Spencer was personally appointed by Missouri’s governor to the Missouri State Dental Board, where he served as president in his fifth year.

Dr. Spencer is well known as a warm and considerate professional who provides exceptional treatment results. He supports his local community and is also a volunteer with the Virginia Brown Community Orthodontic Partnership.
