With the coming holiday, it is a fitting time for the team at Endeavor Business Media (EBM) to recognize some recent personnel changes and to give thanks. 

A few weeks ago, John Ehlen completed his lengthy career in the HVACR market ― retiring from his role as Sr. Account Manager and Publisher of the NATE Magazine (which EBM produces on behalf of the North American Technician Excellence organization). Throughout his tenure, John actively represented several brands across the EBM portfolio including Contracting Business, HVAC-Talk, CONTRACTOR, HPAC Engineering, The NATE Magazine, and American School & University

John’s decades of experience in the HVAC industry -- first working for Honeywell and then spending 20 years in the HVAC media market with EBM and its predecessors -- provided him with unmatched knowledge and insight into our industry. John successfully translated that experience into actionable information for his long list of clients. He worked tirelessly to find ways to help his customers get their unique messages in front of EBM’s audiences of contractors, engineers, and end-users. John’s commitment to the HVACR industry was appropriately recognized in 2012 when HARDI awarded him the Outstanding Dedication Award and again in 2017 when AHRI presented him with their Public Service Award.
No one person could replace John’s history, experience, knowledge, relationships, and passion for this industry. It for that reason we wanted to take this moment to say, thank you.

Thank you, John, for what you have done for your friends, your coworkers, your customers, and your industry. We will miss you John, but we are so pleased you are starting an exciting new chapter of your life. Best wishes from all of us on the EBM Buildings & Construction Group team.     

Exciting New Addition to the Endeavor Business Media Buildings & Construction GroupEndeavor Business Media (EBM) welcomes Bill Boyadjis to the team. He will serve as Associate Publisher of CONTRACTOR and Account Manager for the Buildings & Construction Group. This is an exciting homecoming for Bill, as he previously worked for Penton Media (EBM’s predecessor) up until about 5 years ago. “Bringing
Bill back on the team underscores our commitment to plumbing contractors and engineers, the plumbing industry, and our CONTRACTOR brand,” says Mike Hellmann, Vice President of Buildings & Construction at EBM.

Bill’s prior relationships with the Buildings & Construction Group and his deep knowledge of the plumbing market have empowered him to hit the ground running. He is already helping shape the future direction and vision of EBM’s CONTRACTOR brand while simultaneously learning about the large portfolio of other EBM B2B brands that can support his customers’ marketing efforts.

“I’m thrilled to once again be working with Bill,” says Mike Eby, Group Editorial Director – Buildings & Construction. “We’re excited to see the changes that Bill and Steve Spaulding, Editor-in-Chief of CONTRACTOR, will implement in the magazine, which will benefit both readers and customers.”

Keep an eye out for Bill, whether via phone, email, Zoom, or in-person (once we can safely meet face to face again).
