Dr. John D. Callahan

dr callahan

Dr. John D. Callahan grew up in the Strathmore area of Syracuse and later in Manlius, graduating from Christian Brothers Academy in 1972. He received his undergraduate degree from the University of Notre Dame and earned a Doctorate of Dental surgery from Georgetown University. In 1982 he received a post-doctoral degree in orthodontics from St. Louis University and returned to the Syracuse area to join his father’s practice.  To differentiate the two “Drs. Callahan,” he was called “Dr. John,” a nickname used by patients and staff to this day.

Dr. John is actively involved in strengthening the orthodontic profession. He is a recent past president of the Northeast Society of Orthodontics (NESO), which includes New York, the New England states and the eastern Canadian provinces. On the national level, he is the trustee to the American Association of Orthodontists representing NESO. He is in line to be president of the American Association of Orthodontists.

Dr. John and Callahan, Flanagan, Smith and Stock Orthodontics are recognized as leaders in providing excellent care and service to the Central New York community. This was recently highlighted when Dr. John was named a Fellow of the Pierre Fauchard Academy. This highly selective, international Academy recognizes dentists who have shown exceptional professional, community, and societal leadership.

Dr. John has been happily married since 1982 to Elet, a professor emerita of law and public policy at the Whitman School of Management at Syracuse University. His son, Michael, attended Rochester Institute of Technology and is now an entrepreneur in the Rochester area. When Dr. John is not creating great smiles or working with NESO and the AAO, he can be found cheering at the Carrier Dome.

Dr. John truly loves what he does. “Our patients are great people, and our staff is caring and terrific. We create healthy mouths and great smiles and have fun doing it.”

Dr. Thomas J. Flanagan

dr flanagan

Dr. Thomas J. Flanagan is a native of Pittsburgh, Pennsylvania and received his dental and orthodontic degrees from the University of Pittsburgh.

Dr. Flanagan's desire to provide his patients with excellent orthodontics led him to earn the highest and most difficult designation an orthodontist can receive—that of Board Certified Diplomate. Only a small percentage of orthodontists in the United States are board certified.

Dr. Flanagan believes in not only providing excellent state-of-the-art orthodontics, but providing it in an empathetic and caring manner. He also wants his patients to enjoy their time spent with the Callahan, Flanagan, Smith, and Stock orthodontic family. Dr. Flanagan's favorite time in treating his patients is when their braces are removed, and they see their beautiful new smile for the first time. He particularly enjoys seeing the newfound confidence received from having healthy, straight teeth that can last a lifetime!

 

Dr. Vincent L. Smith

dr smith

Dr. Vincent Smith was born in Kansas City, Kansas, and grew up in northern Virginia. He received his undergraduate degree in Biology and Microbiology from the University of Kansas and his dental degree in 1988 from the Medical College of Virginia. He received his orthodontic certification and Master of Science degree in 1990 from the University of Detroit Mercy.

Dr. Smith is involved in numerous professional and community activities and lives in Fayetteville. He has been happily married for 25 years and has three handsome sons, Collin, Brendan, and Austin. He enjoys snowboarding, biking, soccer, basketball, and the beach, but his greatest joy is his family.

He has been known to ask his former patients in public places about their retainers—hopeful they are still wearing them. His goal is to give his patients the attention they deserve while providing excellent orthodontic results, every day!

 

Dr. Gregory J. Stock

dr stock

Dr. Gregory J. Stock is a native of Pittsburgh, Pennsylvania. He received his undergraduate degree in Biomedical Engineering from Johns Hopkins University and his Doctorate of Dental Surgery from the University of Maryland Dental School. His orthodontic degree is from the University of Michigan. Dr. Stock is also a Diplomate of the American Board of Orthodontics.

Dr. Stock is a member of the Onondaga County and Oswego County Dental Societies. He likes to keep current with recent advances in orthodontics, and his research on orthodontic treatment protocols was published in the November 2011 issue of the American Journal of Orthodontics and Dentofacial Orthopedics.

Dr. Stock and his wife, Anne, have been married since 2007. Anne grew up in Syracuse and is a former CFS patient! Dr. Stock is an avid football and hockey fan and enjoys rooting for all of the local Syracuse sports teams.
