Our Team
Building for People, With People
When you hire GH Phipps to construct a building, or campus of buildings, you get more than a construction company – you have a team of employee-owners. Our leadership supports our people, clients, and community through our company mission: Inspire. Lead. Deliver. Expect an Exceptional Building Experience.

Todd Ruff
President
Todd graduated Summa Cum Laude from Colorado State University with a Bachelor of Science degree in Construction Management. His exposure to the construction industry began early with his father working in construction and Todd often spending time on job sites.
After six years at GH Phipps, Todd was elected to the company Board of Directors–at age 28–the youngest member in Phipps’ history. In 2014, Todd was named a “Top 20 Under 40” with ENR Mountain States Magazine. Todd maintains his LEED AP BD+C, ASHE Certification, is a graduate of the AGC Executive Leadership Academy, and volunteers with the CSU Construction Management program.
Todd’s leadership includes a full understanding of client responsibilities, as he owned and operated his own landscape maintenance business from middle school through college, a job that allowed him to pay for his education. Major projects for which Todd previously provided preconstruction services include the $143 million Children’s Hospital Colorado East Tower Addition, the $70 million Platte Valley Medical Center, and the $61 million Boulder Community Hospital, among many others.
