Marvin graduated from Texas A&M Commerce in 1972 and took a temporary position with a refrigeration service company until he could decide what to do after college. He never left the trade. The company he worked for ran into financial difficulty in late 1977 and Marvin bought the inventory, a worn out service truck and the phone number and founded Refrigerated Specialist in January 1978.

From that meager beginning Marvin and his team have built an organization that employs over 100 people today. The late 70’s and all of the 80’s were the founding years of casual dining and Marvin was excited to serve that industry. He traveled Nationally and Internationally installing refrigeration and ice machines for chains such as TGI Fridays and Chili’s during their explosive growth period.

Jean Hester, Marvin’s wife, was an integral part of their success raising their two children, Shelly and David, all while maintaining the house and running the back of the house operations for RSI for many years.  That included answering the phones and sending the calls to Marvin via the latest in technology …  a pager. Not a digital pager but a tone only pager which required a call back to get the call.  Jean retired in 2003.

Marvin has dedicated his time to his family and his work family for 45 years. Outside interest are Cycling and Travel. Marvin competed in Texas Mountain Bike Association Racing for five years ending as the over 60 Cat One State Champion in 2009.


Scott Hester was born & raised in Dallas, Texas. His hobbies have included racing motocross, enduro and motorsports as a spectator. Today he enjoys long distance motorcycle touring & all activities with family. He is married to Sharon Stone-Hester and has 2 daughters, Megan and Amanda & 1 son Logan. Their home is in Rockwall, Texas.

In 1978 he joined his brother at Refrigerated Specialist, Inc (RSI) and began a career that has exceeded 4 decades in the food equipment service industry, today serving as president. In 1985 he formed Refrigerated Equipment & Leasing L.L.C.(REALCO) providing a total cost of ownership leasing solutions to the market for ice makers & frozen beverage equipment. In 2002 he formed a partnership Cooking Equipment Specialist, L.L.C (CES) and now offering the industry complete installation, service, parts & leasing solutions.

Industry participation has included over a decade of service to the Commercial Food Equipment Service Association (CFESA) beginning on the education, business technology, finance & NAFEM Liaison committees, developing & instructing refrigeration classes, serving as Regional Chair, Director, Treasurer, Vice-president, President & currently seated as Past President.   Additionally he has written or participated in numerous articles for trade publications, subject matter expert panels and expert witness testimony.

In 2003 Scott was honored with the Top Achiever Award in the Service Agent category by Food Equipment & Supplies Magazine. In 2010 NAFEM Doctorate of Foodservice was awarded along with recognitions by MAFSI & FEDA. In 2011 RSI & CES were recognized as Manitowoc’s STAR Service Network’s Rising Star award. He is the 2012 recipient of FER Mag’s Lifetime Achievement (old guy that stuck around) award for 2012-13.

He has found the greatest reward of his professional life in coaching & mentoring the success of others during the last 20 years in his multiple leadership roles.
