John Ostermann started as a veterinary student. But after a month of Zoology, he decided maybe this was not for him. His love of animals came from a childhood spent on his grandfather’s farm. John’s grandfather was a carpenter and cabinet builder as was his son, John's father. When John saw a roommate drawing architectural plans, John thought "Maybe I will give this a try.

Six years later, he graduated with a Bachelor of Architecture from Kansas State University and became a registered architect in Kansas in 1977.

After several entry-level jobs in architecture, John took a job with a metal building contractor as the architect for design build contracts. There, John became familiar with estimating and project management. This added skill set and a desire to advance, opened a new career path at R.D. Andersen Construction Co. in Topeka. During his nine-year tenure, John worked on large public bid market projects such as the Applegate Energy Center for the University of Kansas, Lockton Insurance Office Building in Prairie Village, Kansas and The Golf Course Superintendents Association of America headquarters in Lawrence, Kansas.

When R.D. Andersen closed its doors in 1992, John decided to pick up where they left off and ALTMAR Inc. General Contractors was formed.

Matthew Ostermann started as a computer engineering student. But after one semester of Intro to Java, he decided maybe this was not for him. Later when a college roommate said he had to finish drawing a barn for class, Matthew asked “What major requires students to draw a barn?”

Architectural Engineering was the answer.

Matthew, loving math, and growing up in the construction industry thought, “Maybe I will give this a try.” Six years later, Matthew graduated Kansas State University with a Master of Science in Architectural Engineering and a Bachelor of Science in Construction Management.

Matthew earned his Kansas Professional Engineer License after immersing himself in the engineering industry designing restaurants, portions of power plants, and box retail stores in 46 states. Then in 2011, Matthew joined ALTMAR, Inc. as a project manager and estimator. 

In 2016, Matthew left ALTMAR Inc. to start his own Residential Design Build Firm in Colorado and earn his Colorado Engineering License. Returning to Kansas in 2017, Matthew rejoined his father, and ALTMAR Inc. General Contractors became Altmar Enterprises, a name more accurately describing the wide variety of services the company now offers.

John and Matthew together, through Altmar Enterprises, bring a love of building and 65 years of experience within the construction industry to the table. Commercial, Residential, Design, Engineering and Development—there is little in the industry that is not within their capability and combined experience.

"The solution is not to entice people with a sweeter carrot or threaten them with a sharper stick. We need a whole new approach, built around the desire to do things because they matter, because we like it because they are interesting and we are part of something important. This new operating system has three elements: Autonomy, Mastery, Purpose. Autonomy: the urge to direct our own lives. Mastery: the desire to get better and better at something that matters. Purpose: The yearning to do what we do in the service of something larger than ourselves."  – Daniel H. Pink
