John C. McCaffery


John has called Atlanta home since graduating from Mercer Law School in 1989. For twenty-five years, John was a sole practitioner specializing in all aspects of family law, including divorce, prenuptial agreements, wills, and contested probate cases. His resume also shows more than two decades of experience defending DUI and criminal cases. Many of his criminal cases involved domestic violence, temporary protective orders, and other family law-related issues.

Senior partner Mary Montgomery believes he is the perfect fit for SM&P. “John’s level of experience will be an asset to our firm. His care and genuine concern for his clients make him a welcome addition and complement to our current attorneys’ skill sets and commitment to service.”

John is excited to be part of the SM&P team where he can apply his thirty years of legal experience tenaciously representing clients in all capacities of family and criminal law. “I am impressed by the high quality of the attorneys and support staff at the firm,” he said. “I know I will enjoy working on more challenging cases in this very supportive and professional environment. I am willing to take on hard cases and endure difficult circumstances -- anywhere, any conditions, any time.”

John is active in the Lawyer’s Club, the Atlanta Bar Association, and GACDL (Georgia Association of Criminal Defense Lawyers). He and his wife Cassy of 29 years are proud supporters of Georgia CASA (Court Appointed Special Advocates) and The Eric R. Beverly Family Foundation for Breast Cancer. John is also a member of the Atlanta Botanical Garden. Before joining SM&P, he spent two years giving back to the Atlanta community by providing a vigorous defense for indigent clients in Fulton County as an attorney with the Georgia Public Defender Council.

The McCafferys reside in the Buckhaven area of Fulton County. They share their home with two beloved rescue dogs. In his leisure time, John enjoys gardening home repair and maintenance, attending summer concerts at Chastain Park, and cheering on the Georgia Bulldogs football team.
