Jon McMahon

Born in Scotch Plains, New Jersey then later living in New York City, Jon has always been interested in real estate. From his first home purchase in 1998, to future investments throughout the state of New Jersey. Jon expanded his holdings to Park City Utah, Gulf Shores Alabama, Inner Harbor Baltimore, Las Vegas Nevada and Prescott Arizona. Honing his skills and knowledge along the way.

What started as a hobby was now becoming a passionate career. Whether on vacation or just traveling Jon made the time to meet with realtors and learn about the areas and the industry. It was during this time Jon was introduced to Nick, an experienced builder in the Phoenix Arizona with a 20-year track record in home construction. This introduction has led to the next chapter for both men in Prescott, Arizona and the Granite Creek Development Group LLC.


Jon’s zest for life along with his entrepreneurial spirit is welcoming amongst his peers and business partners. Jon believes in doing it right and if he cannot envision himself living in one of his homes or areas he doesn’t expect you would want to either! Good relationships  and quality people is what keeps Jon motivated. Life is a process and so is home building.
