Meet Your Doctors
Our team of orthodontic specialists draw upon their collective knowledge and experience, employing a collaborative approach to help our patients achieve the beautiful, healthy smiles they deserve
Dr. John D. 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.
SKS Orthodontics is recognized as a leader 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. Brian Kurtzner
Dr. Brian Kurtzner was born and raised just outside of Albany, NY. He received his undergraduate degree in Biology and Chemistry from Le Moyne College. He received his Doctorate of Dental Surgery and then proceeded to obtain a Master of Science degree and certificate in Orthodontics all through University at Buffalo School of Dental Medicine.
Growing up as a patient, and later an employee of his uncle’s orthodontic practice, Dr. Kurtzner has always held a strong appreciation for the impact of orthodontics on patients’ lives. He strives to create a friendly and comfortable atmosphere while providing the highest quality care for his patients.
Dr. Kurtzner and his wife Justine, a Tully native, met while attending Le Moyne College. After spending nearly 10 years in Buffalo, they were excited to make their way back to Central New York and are now the proud parents of two amazing children, Dominic and Elena. Dr. Kurtzner loves cheering on the Buffalo Bills, Syracuse Orange, and watching English Premier League soccer. He enjoys hiking, skiing, and traveling as well as spending time with family and friends.
Dr. Vincent L. 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. Greg J. Stock
Dr. Greg 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. He is a member of the Onondaga County and Oswego County Dental Societies.
An engineer at heart, Dr. Stock loves incorporating new technologies such as 3D printing and customized braces into the practice. He believes these advances empower the doctors to deliver beautiful smiles in less time, and with no putty impressions!
Dr. Stock considers himself a “local-in-law” as his wife, Anne, is a Syracuse native. He loves to travel with his wife and two daughters, Claire and Lauren. He says that he gets along so well
with his patients because he is a kid at heart. Feel free to talk to him about Disney, Marvel, Star
Wars, Harry Potter, or Percy Jackson!
