At Keller, the Hall of Fame is our way of honoring our people. Induction into it is reserved for team members who, through time and dedication, have left a lasting impact on clients, co-workers, and the company, and retired successfully.

Some of our people: And potential future hall-of-famers? We’d like to think so.

Keller Associates opened its doors in 1993 in Boise, Idaho.  Our first clients fell within Jim Keller’s wheelhouse – municipal clients who needed personal attention, creative engineering solutions, and bold approaches to secure funding to pay for much needed projects.

A successful transition occurred upon Jim’s retirement in 2008, which led to a mindset of “perpetual leadership” that was fostered by creating opportunities and career paths for individuals within the company to grow and succeed.

From these humble beginnings, we have grown to 120+ team members with offices throughout the west that are bound by a commitment to excellence and a growing reputation of service.  The future is bright.



Susan Burnham

Susan Burnham was our go-to person during her 16 years with Keller Associates. Everyone wanted to work with Susan. She was thoughtful, thorough, and even loved to proofread! Before joining Keller, she had more than 25 years of experience in the consulting industry. She was our own pioneer having been one of the first women Professional Engineers licensed in the State of Idaho. Her engineering excellence, reliability, and leadership led to a position as a trusted member of Keller Associates’ Board of Directors where she served for three years before she retired.

Susan and her husband, Arlen, are enjoying retirement life, currently calling Arizona home. They are spending as much time as possible in their motorhome living the nomadic life and experiencing the great things this world offers. Susan left an excellent legacy with Keller Associates that will not be forgotten. Safe travels Susan!


Glen Holdren

Glen joined Keller Associates in 2005. Glen’s contributions and commitment to excellence made Keller Associates a better engineering company. Glen excelled in developing wastewater treatment plant engineering designs in an efficient and timely manner. Glen got things done! With vast technical skills focused on our largest and most complex projects, his efforts influenced our success and benefited numerous clients and communities. Glen “semi-retired” in 2015. He still pitches in at work: but on his own terms and schedule. Retirement is treating Glen and his wife, Dena, well. He now has the time to pursue his interests outside of engineering including skiing, golfing, hiking, biking, and traveling around the world.

Jim Keller

As founder, mentor, and role model, Jim successfully established an excellent engineering practice – one that is built on integrity, honesty, and trust. For decades, he was known as the engineer who could get projects completed using creative funding approaches and strong engineering design. Throughout his career, Jim liked to spend time on the road visiting people and sharing experiences. Client service first was his mantra which permeates our company today. He is a master listener and questioner. Over the course of his career, Jim helped many communities, enriched countless relationships, and touched so many lives. Jim retired in 2008.

Jim and his wife, Renee, now spend their time fishing, riding RZRs, enjoying family, and being involved in their church missionary and service efforts.

Dennis Suihkonen

During the initial years of the company, Dennis provided the engineering expertise to successfully complete the building block projects that firmly established our organization. Dennis worked on many water and wastewater projects including designing the first Temperature-Phased Anaerobic Digestion System to create Class A biosolids in the Western United States for the City of Blackfoot. Dennis retired in 2010.

These days you’re likely to find Dennis playing golf and tennis and taking his golden retriever for hikes in the foothills. He and his wife, Marty, are also enjoying the extra time they now have to spend with their grandson in Utah. Strong serves Dennis!
