Growing up I was always curious how and why things went together a certain way and eventually explored different ways to do this. At some point in middle school, I was introduced to the concept of an architect and had the opportunity to job shadow one and from that point on I knew it was what I wanted to do with my life. I have since graduated from North Dakota State University with a Master of Architecture degree and will continue my passion for architecture in my career. Outside of work I enjoy being outdoors doing absolutely anything, whether it is hunting, fishing, boating, or something similar. I also enjoy traveling and road trips with my friends or family and can find an interest in any part of the world.

I have always known that I wanted to enter the profession of interior design because my grandpa owned a successful modular home business. I enjoy creating spaces that have a lasting impact on people and their surroundings. It is inspiring to see how beautiful design can truly transform a space. As I continue my education at North Dakota State University, I am excited to be a part of the RLE team to grow my knowledge and gain real-life experience within the industry. Outside of work, I enjoy being on the lake, spending quality time with friends and family, being outdoors, and exercising.

For the past five summers, I have been framing residential homes in the Fargo/Moorhead area, which is where I discovered my interest in Architecture, and continued to grow in my knowledge of the physical construction side of a build. I have always enjoyed getting my hands dirty in the field, but with my Master’s in Architecture from NDSU, I have been able to enjoy the design side of things where I can use my own creativity to construct a solution for all client needs. Being a part of an accomplished team at RLE, I can let my experience make a difference and give it a purpose in real world applications. Outside of work, I tend to spend my time playing sports of any kind including summer league softball and volleyball. During the school year, I play on the Men’s Club Soccer team at NDSU and am currently a co-captain on the team for my fifth and final year of college. I like to keep myself busy and always jump from one activity to the next while I still have the energy to do so.

With 20+ years of total experience in the field of Architecture, I have enjoyed collaborating with several great Designers and Design Firms on innovative projects throughout the country. Over the years I have gained extensive experience in large, phased development projects while establishing expertise in the areas of retail, hospitality & high-rise tower design. I enjoy the process of starting a project to seeing the final outcome.

I joined the RLE group in 2016, bringing more than 22 years of CAD experience on commercial, educational, medical, liturgical, multi-family, hospitality, residential and remodel/renovation projects. I’ve been married to my wife Trina for over 22 years. We have two daughters, Addyson and Brenna, and a dog, Bailey. Outside of work I enjoy spending time with family, weekends at the lake, and hunting and fishing.

Project Accountant

I began with RLE in 2014 and have over 20 years’ experience in a variety of financial/accounting roles, ranging from health services to a multi-divisional manufacturing company. I graduated from North Dakota State University with a BS degree in Statistics and from Minnesota State University Moorhead with a BS degree in Accounting. Outside RLE, I also work for H&R Block as a Tax Specialist during the tax season. Away from work, I am a sports fanatic, attending as many live sporting events as possible, watching the ones I can’t attend on TV, and volunteering at my daughter’s high school athletic events. I live in Fargo with my wife, daughter, and 2 pets.

I’ve been the Corporate Accountant at R.L. Engebretson since 2009 and am responsible for all aspects of the firm’s finances. I attended college at the University of North Dakota and majored in Finance and Human Resources. When not at work, I enjoy spending time outdoors, including hiking, biking and summers at the lake. Once winter arrives, I enjoy cheering on the UND Fighting Sioux hockey team.

Madeline Nelsen

I've always been drawn to the way thoughtful design can shape how people experience a space. After earning my degree in Interior Design from North Dakota State University, I continued pursuing my passion for design and eventually joined the RLE team, where I work on a variety of commercial projects, helping bring spaces to life through finish selections, space planning, and construction documentation. One of the most rewarding aspects of design for me is balancing creativity with problem-solving and seeing a project evolve from an initial concept into a completed space. Whether I'm working on financial institutions, retail environments, or workplace projects, I take pride in creating spaces that are both functional and welcoming for the people who use them every day. Outside of work, you'll often find me caring for my ever-growing plant collection, playing guitar, traveling, hiking, or spending time with my fiancée and our three cats.

“Learn something new every day.” Since joining RLE in 2015, I am amazed at how much I have learned from a creative group of architects and designers. As an Assistant Project Manager and Drafter, I have the benefit of working on design, project management, and production, which makes every day new, exciting, and full of learning experiences. In my free time, I spend as much time as possible on the golf course, at the lake, and with family and friends.

Keaton Schwab


Student - Architecture
Email: keatons@rleco.com

Architecture has always appealed to me because it combines creativity, problem-solving, and the opportunity to design spaces that have a lasting impact on the people who use them. As an Architecture student at NDSU, I’ve enjoyed applying what I’ve learned in the classroom to real-world projects at RLE while continuing to develop my design and technical skills. Outside of work, I enjoy staying active, following sports, traveling, and spending time with family and friends. I like staying busy, exploring new things, and trying new experiences whenever I can.

As part of the RLE team, I help ensure that drawings go out correctly and on time for our clients by coordinating with others on the project and efficiently detailing the various building components. Outside of the office, I like to spend time with my husband and our two cats and learn new types of crafts. I also have a love for fitness and working on my physical wellness.

The pursuit to improve ourselves and learn something new every day enriches all our lives. Our senses and emotions are motivations that provoke the built environment to respond and inspire everyone to participate in life. It’s the spaces surrounding us that frame our memories and help shape who we are. I feel blessed to be able to help communicate that through architecture. Understanding others, listening, and putting their needs above yourself is a main tenet my family strives to achieve. Communicating well with each other is paramount, regardless of where it’s applied.

I have been in the architectural world for 14 years, all of which have been with RL Engebretson. As a CADD Technician, I take pride in working as a team to put together an outstanding set of construction documents. I have the wonderful opportunity of working from my home, isn’t technology great! As my children return home from school I can easily transition to my role as a mother. I enjoy playing cards and games with my family as well as watching my boys play football, basketball, and baseball. The bleachers haven’t gotten any softer! I also enjoy baking, cookies anyone?

It’s hard to believe that around 90% of our time is spent indoors. I find it amazing that I am part of a group of creative and intelligent minds that help imagine and shape the spaces we spend so much time in. As a Project Manager, I help organize and guide those minds into producing environments that our clients love to work and play in. As a bit of a perfectionist, I want to make sure our clients are satisfied. As our tagline says: Results. Done Right. I truly believe those words and do everything I can to make sure that happens. After I hang up my Project Manager hat for the day, I start my night job as a mother of two boys and a wife of a hard-working man. At home, I make sure my troop of men are well fed and cared for and maybe find some time for a little fun as well. Did someone say Legos? I’m in.

Our interior spaces are constantly evolving to harmonize how we work, live, and play. After over two decades of designing interiors, I still get a twinkle in my eye and burst of energy when in the element of designing concepts for a new project. The interiors of a corporate lobby with stiff chairs of twenty years ago have progressed to a welcoming lounge area with a coffee bar and fireplace. Studies confirm that ergonomics, colors, textures, lighting, and flow all have huge influences on our daily moods, ability to focus, and productivity. Signature elements you will find in many of my projects are 1) functional, yet unique space planning; 2) detailed ceilings incorporating various lighting and; 3) commissioned local artists. These components touch our senses bringing comfort to all users. Outside the office, you will find me cheering on my growing kids in their sporting events. My husband of over 20 years and I enjoy traveling and exploring new adventures. He often patiently waits for me while I touch materials, crawl under objects to see how they were constructed, and photograph details of natural textures most people don’t pay attention to.
