Mark started in the HVAC and refrigeration business in 1980. He started with Betlem Service Corp. in 1984 as a service technician then moved onto another company as an expert service technician in refrigeration. He expanded his knowledge in the ammonia field of refrigeration. He became part of a 4-man group of emergency response trained with SCBA Air Packs to respond in the event of ammonia refrigerant leaks in the refrigerated warehouses. In 1995 Mark became the Service Manager where he grew the commercial service division by diversifying to multi-year service contracts and increased the industrial and ultra-low services. He returned to Betlem in 2000 as Service Manager.

Throughout the years Mark has continued his education after receiving his Associates in Applied Science, to take various courses in refrigeration, air conditioning, and heating services technologies, and is active in the Refrigeration Service Engineers Society, as a way to keep abreast of new techniques. He has also taken repair courses on air-to-air heat pumps, screw chiller and repair, and modern hydronic and radiant heating systems.
