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.

Senior Engineer


Brett Guarrero has been working in the energy and engineering industry for over 25 years. In various forms, he specialized in energy system assessments, design, project management and commissioning. Over these past 25 years, he has developed many ideas, products and has been issued one U.S patent and filed for three others. Always looking at moving energy from one place to another as efficiently as possible, this moving of energy also relates to the human element of Brett’s work production.

Mr. Forrester, DMA’s principal, always states, “Brett knows everything there is to know about piping.” While we are confident Brett has extensive knowledge in piping systems, his breadth of mechanical system knowledge and design is extensive.

Brett’s portfolio includes work on numerous private residences located in Telluride, Aspen, Boulder and Denver, the University of Colorado, Colorado State University, and Western State University, private business enterprises, municipalities, numerous energy providers, and an award-winning geothermal heating/cooling system designed for the Los Angeles Unified School District.

Brett is certified in geothermal heat pump technology through Oklahoma State University; is a Certified Building Commissioning Professional (CBCP); has received his green building certificate through Colorado State University; is active in the USGBC LEED community; holds bachelor’s degrees in Engineering, Marketing and Finance from Southern Illinois University; and received a Master of Science degree in Organizational Leadership from Regis University in Denver.

At DMA Engineering, Brett is active in developing new business opportunities, spearheading the commissioning side of the business and assisting in giving guidance to junior personnel. Brett’s experience gives DMA a solid depth of knowledge that assists in providing a high-quality product and innovative solutions.

Grant is a Colorado School of Mines Alumnus who could not leave the mountains behind after he graduated. Mr. Mills was born and raised in Dallas, Texas, but had his eyes set on Colorado from vacations in Steamboat as a kid. While at Mines, Grant obtained a Mechanical Engineering undergraduate degree and worked on a green building retrofit project in his capstone Senior Design course. Since joining DMA Engineering, Mr. Mills has passed the Fundamentals of Engineering exam to become a Colorado registered Engineer Intern. Additionally, in his tenure at DMA Engineering, Grant has gained valuable field experience that has shaped his design practices to be efficient and buildable. Grant performed the majority of a mechanical survey of a 1980’s, 40,000 sq. ft. medical office building gathering duct sizes, equipment capacities, and identifying potential problem areas for constructability before drafting as-built drawings and recommending changes to the existing system.

Grant brings a fresh look at old ideas: with his naturally curious thinking he is continually looking further into accepted methods. With the ever-changing energy landscape, it is necessary to reevaluate methods that are merely holdovers from a time in history where our larger impact was simply not considered. Grant has helped DMA Engineering delve deeper into ASHRAE recommended thermal comfort, indoor air quality, and energy efficient design practices as he expands his knowledge of HVAC design. With the combination of Mr. Mills’s fresh book-knowledge and the DMA team’s extensive hands-on history, the designs and concepts that DMA Engineering can present are better than ever.
