The Kaiser-Martin Group Construction Company

A history of excellence in custom building... for people and horses. 3 Generations of masterful residential construction: custom homes, horse barns & equestrian structures


The Kaiser-Martin Group believes the greatest foundation upon which to build is inegrity. Since our founding in 1984, we have always made it our goal to do business with integrity, honesty, and excellence.  We combine this way of doing business with an old-fashioned commitment to quality craftsmanship while maintaining the highest level of performance. We provide all of this at a fair price. We apply this philosophy to everything we do and to all of our interactions with people whether customers, vendors, peers, or our employees.  Through the years we have never forgotten that good business principals are what make for happy and satisfied customers as well as a successful business.


Kaiser Construction Company, Inc. was founded in 1984 by David Leinbach and his father, Christian Leinbach.  In 1986, the company was incorporated with David owning 100% of the outstanding stock. Kaiser Construction was a General Contractor that specializes in the following construction sectors:  Equestrian and Agricultural, Institutional / Ecclesiastical, Commercial / Industrial, and Residential.  Kaiser Construction was advised by a Board of Directors. We are pleased to announce that in 2017, we have merged with our sister company, Martin Construction Company to form the new, Kaiser-Martin Group. This merger enables us to provide a wide variety of services for our customers with the same integrity and dedication to craftsmanship that has guided us all these years.

With over sixty-five years of combined experience in construction and design, we know what it takes to build custom structures on time and on budget.
