Our Team:

Ronald L. Marchal - President

The founder of Marchal/Stevenson began in the commercial industry in 1953. In 1978, he started in the residential elevator business. He pioneered the idea of residential elevators, with the help of most of the major builders and architects in Houston. Together, they incorporated his idea to produce homes as "elevator capable" by stacking closets and dropping the concrete in their homes for a future elevator. Today, Ron's innovative ideas have lead Marchal/Stevenson to be the largest dealer in the world for Inclinator Co. of America.

Ron is originally from New Orleans, Louisiana. He attended Tulane University and served his country in the United States Air Force. He has three daughters.

Douglas G. Yerex - Vice-President

Doug has been part of the family for 38 years. He works with his wife, Debi, and has three children, who all work in the family business. He joined Ron in 1978 to start Marchal/Stevenson Elevator. His primary responsibilities have always been overseeing all aspects of construction, outside sales and troubleshooting. He has a keen eye for helping design new technical ideas, improving today's elevators.

Doug attended Sam Houston State University. His hobbies are traveling and hunting.

Deborah M. Yerex - Vice-President

Debi is Ron's daughter and has been a part of the family business since its inception. She oversees inside sales, marketing and manages the maintenance department.

Mark M. Mellecker - Vice-President
