As Vice President of Sales, Dennis is responsible for building new relationships with agencies, advertisers and direct marketers, and sharing with them the unique personalized and trusted service that has become a hallmark of our organization. 
Dennis came to OTSM in 2017 after a successful twelve years at analytics company Teletrax, now a part of 4C, the data science software company. There Dennis served in a variety of roles, most recently as Senior Director of Sales and Business Development. Dennis’ work history prior to Teletrax includes a variety of roles related to this industry, ranging from software sales to production services.
"I’ve known, and in many instances partnered, with the On The Spot Media team and know their strong commitment to client service isn’t just marketing speak, but a foundation of the organization," he said. "That’s very important to me and I’m really excited to be here."
A devoted father and husband of 34 years, Dennis is a Philly sports fan, and a bit of a self-described golf fanatic. His most memorable round ever played was at the Ocean Course at Kiawah Island, SC.
