TerraVest Industries Announces Sales Team Expansion & Retirement of Industry Veteran

Clio, MI (July 8, 2026) — TerraVest Industries announced updates to its sales team — with the addition of Michael Maravelias and David Edmondson — and the upcoming retirement of David Archer. 

David Archer will retire on July 31 after 38 years in the propane and anhydrous ammonia industry. His career began in 1988 at Propane Transport International and included leadership roles at McIlvaine Trucking, American Welding & Tank, Trinity, Arcosa and TriArc before he joined TerraVest in 2023 as key accounts manager. 

“David’s impact on this industry extends far beyond his professional accomplishments,” said John Hearn, vice president and general manager of TerraVest Tanks. “He has built lasting relationships throughout the propane community and has been a trusted advisor to customers, colleagues and industry partners alike. We are grateful for his contributions to TerraVest and the industry as a whole, and we wish him all the best in his well-earned retirement.” 

Assuming responsibility for the territory previously managed by Archer, David Edmondson will transition into the role of territory sales manager for the Midwest region (Michigan, Ohio, Indiana and Illinois), effective July 6, 2026. Having served as general manager of TerraVest Tank’s facility in Kaleva, Michigan, Edmondson brings a well-rounded perspective that supports both operational alignment and the development of long-term partnerships. 

“In today’s competitive landscape, we need someone who can step in and aggressively grow our market share, and David is the right person for that,” said Hearn. “Customers love working with him, and he will be very successful with this transition.” 

Effective July 1, Michael Maravelias joins TerraVest as key account manager and inside sales. Previously recognized as one of Manchester Tank’s top-performing sales representatives, Maravelias will serve the Northeast and Mid-Atlantic Regions, working alongside Don Nichols. 

“We are excited to welcome Michael to the TerraVest team,” said Hearn. “His industry experience, customer-focused approach and proven sales success make him a valuable addition to our organization as we continue investing in growth and service across North America.” 

“With Michael, David, and the rest of our sales leadership team, we are well-positioned for the future,” said Hearn. “While David Archer’s retirement marks the end of an exceptional career, we are confident that the foundation he helped build will continue to support our customers and our growth for years to come.”
