Ronald L. Marchal - Founder

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

Ron was originally from New Orleans, Louisiana. He attended Tulane University and served his country in the United States Air Force. Ron was called home to be with his Lord and Savior in 2016. He left his legacy to his three daughters, Debi, Jeanne and Jenni.

Deborah M. Yerex - President

Debi is Ron's oldest daughter. She has been part of the family business since its inception. She oversees inside sales, marketing, and the maintenance department. Her main objective for the maintenance department is to provide quality service for all customers. Our company motto is "The best service after the sale".

Debi's hobbies include traveling and gardening. She also enjoys showing horses with her daughter and granddaughters.

Douglas G. Yerex - Vice-President

Mark M. Mellecker - Vice-President
