Paul Kapetanakis was born on February 12, 1952, in Boston, Massachusetts. Of Greek heritage, he grew up in the Roxbury neighborhood before descending into drug addiction, motorcycle gang violence, and criminal activity under the alias “Mad Dog.” After serving time in Massachusetts correctional facilities, Kapetanakis entered a drug rehabilitation program that became the turning point in his life. He completed trade school in refrigeration service in 1970, followed by college coursework in restaurant management and design. He also completed the Dale Carnegie Sales Course, served as an assistant instructor, and spent six years as a Toastmasters International speaker.

Following his recovery, Kapetanakis built a successful 20-year career in foodservice equipment sales, earning Salesperson of the Year 8 times and designing the first Great Steak & Potato restaurant. He became a public speaker on addiction prevention, working with schools and community organizations.
