Who We Are and What We Believe In

We believe being creative about saving energy (and therefore, saving you money) is an amazingly important part of residential and commercial buildings, and we feel fortunate that we’re able to help owners and everyone in the design and construction industry make our world a slightly better place.

For most people, engineering can seem a little “dry” and “picky”. So, while everyone here at DMA Engineering does super-cool stuff like extended travel, mountain biking, rock climbing, car racing and skiing, our presence is to make the world a better place by providing efficient systems.  We take efficient to mean both our designs and how we run the business.

DMA Engineering is a progressive firm that works hard to balance life and work, and believes our projects should be as unique and interesting as our associates. Since we support the idea of humans having a smaller carbon footprint, a flexible work environment.

We are members of ASHRAE, AIA and the Colorado Green Building Guild.

Steven started DMA Engineering because he felt he could make a difference in the world through his engineering talents: By designing high quality renewable energies for residential and commercial buildings.

Mr. Forrester is a Colorado native who grew up in the Washington Park neighborhood. While obtaining his undergraduate Mechanical Engineering degree at the University of Colorado at Denver, he worked as a carpenter. This early construction experience has given Mr. Forrester valuable hands on experience in how a building is constructed. After graduating, he worked in industry for several years. Initially, he worked for an Air Force subcontractor that was responsible for the sustainability of radio frequency antennas. After several years he moved on to a local commercial kitchen manufacturer designing and building refrigerators. While working he returned to the University of Colorado at Denver to receive a Master’s Degree in Mechanical Engineering and his Professional Engineer’s license. He then moved on to designing transportation equipment while concurrently starting DMA Engineering.

Steven’s primary responsibility is to aid in all sustainability and energy modeling components of a project. In addition, he manages staff resources, provides technical assistance to the team and performs quality assurance/quality control on all deliverables. He checks-in periodically with the project team to see how the projects are going and how DMA can improve providing engineering assistance.
Steven brings 19 years of engineering experience with mechanical engineering, energy modeling, commissioning, and has been the Engineer of Record for the planning and design of numerous building projects.


Associate Engineer

Cody Young earned his bachelor of science in Mechanical Engineering from the Colorado School of Mines in 2015 and is currently registered as an Engineer in Training. He is currently working to gain more industry experience and obtain his professional engineer’s license. Cody has completed intensive training through ASHRAE to further his education in the HVAC field. Cody has had an immediate impact at DMA engineering working as a mechanical designer.



Donna is a long time Colorado resident who graduated from Colorado State University in 1994. She has worked for Hewlett Packard with mechanical systems responsibility for Class 10 and Class 100 cleanrooms as well as mechanical systems engineer for office space and manufacturing floors. She was responsible for high purity gas systems design review and served as site hazardous materials lead for the Fort Collins build out of a 50,000 sq ft integrated circuit fabrication facility. She continued as high purity gases engineer for the facility after Agilent Technologies was formed.

For Lockheed Martin she was a mechanical engineer/project manager for reconfiguration of classified spaces at the Joint National Integration Center in Colorado Springs. After being licensed as a Professional Engineer, she moved to the Lockheed Martin Waterton Canyon Site as the site Mechanical P.E. doing full design of upgrade projects and review of out sourced engineering projects.

After retiring she was still excited about doing engineering and has returned to help with mechanical design and design/code reviews.
