J.C. Granger | CEO  


After over a decade serving as a senior marketer for corporations, J.C. decided to launch Infinity Marketing Group in 2011. He finds particular joy in empowering small-to-medium sized tech companies to grow their business and find a voice online. J.C is a passionate and skilled marketer who takes pride in Infinity Marketing Group’s ability to deliver the best experience for its clients.

Growing up in Silicon Valley left J.C. with a strong impression of the importance of technology in business and innovation. This, combined with a degree in Psychology from University of Colorado at Boulder, led him to hone his expertise in consumer psychology and digital marketing support for the tech industry. When not meeting with clients, J.C. can most often be found traveling, snowboarding, skydiving or (most importantly) spending time with his daughter.

Operating a brick-and-mortar storefront where the children they serve can “shop” for new clothes (provided for free), Clothes to Kids Denver helps Denver’s kids afford the dignity that comes with new, well-fitting clothes.
Clothes to Kids Denver has been the recipient of several of our charity events. Not only have ticket proceeds gone to the organization, but we have also held fundraising auctions where guests at our networking events can bid on items like prime seat tickets to a Colorado Rockies baseball game!

Mommy and Me Cancer Foundation

Cancer sucks. Dealing with cancer while you’re a single parent sucks even more. Mommy & Me Cancer Foundation works to help mothers who are solo-raising their children not only get the support they need for their cancer treatment but also get the support they need to make sure their child is cared for during doctor’s appointments, hospital stays and more. Plenty of people say raising a kid is exhausting—doing so while drained due to treatment requires extra help.

Infinity Marketing Group is proud of the support we’ve offered MAMCF and the individual dauntless parents the foundation represents.
