Meet Our Doctors

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.

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 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 Syracuse to join his father's practice.

Dr. John is actively involved in strengthening the orthodontic profession. He is the current president of the Northeast Society of Orthodontics (NESO) through 2012, which includes New York, New England and the eastern Canadian provinces. On the national level, he is a member of the Council on Insurance for the American Association of Orthodontics (AAO).

Dr. John has been happily married since 1982 to Elet, a professor of law and public policy in 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, playing golf or racquetball, scuba diving and enjoying the company of family and friends.

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

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 and Smith 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. Flanagan lives in the Fabius-Pompey area where he is active in the community with his wife, Cindy, and daughters, Janelle and Shauna.

Dr. Vincent Smith was born in Kansas City, Kansas. He 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 and Masters of Science degrees 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 23 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, everyday!

I have been a Dental Hygienist in the specialty of orthodontics for 44 years. In fact, I have spent my whole career in this very practice!! Is there any doubt that I love my job?

I love seeing the change in patients that a new smile can create.

I have been a Lab Technician for Callahan,Flanagan,Smith & Stock Orthodontics for 14 years. A great part of my work here is being creative, fabricating all the different appliances utilized for our patients during various stages of their treatment. What is especially rewarding for me is helping our patients that are in the "waiting game" for implants by providing them a special retainer that gives them their full smile until implants are completed.

My creativity continues away from the office. My husband and I are still finishing up final touches on our home which we are building ourselves. I love spending time with my family and my kittens Cocco and Blu.

I'm a dental assistant and have worked for this wonderful CFS&S pracrtice for 9 years.
