We’ve been honored to have the opportunity to support many Colorado’s most
exciting companies over the years, including:

“I have run HR in Fortune 500 companies and now I run HR in a 100 person diagnostic start-up in Boulder. I knew what we needed to build but as a small HR shop we had limited capabilities and resources. I reached out to Summit HR Solutions to see if they could become my partner and become the extended HR functional team that I needed but could not justify having full time to tackle some big HR initiatives that needed attention.

Fred Holt understood my issues and introduced me to one of his top consultants, Melissa Grandchamp to come in on a project based engagement. Melissa worked with our entire team to build out and implement a performance system and a talent management infrastructure with approaches and tools appropriate to our size and complexity.

Melissa came on with us in August 2015 for 2-days a week working with our HR team to build a robust Talent Management system. We now have a cloud-based performance management application in place, our employees have goals with direct line of sight to our corporate key results, and we are rolling out ongoing training programs to facilitate continued employee and leadership development and ensure engagement. With Melissa’s involvement we are now accomplishing a number of key initiatives that has added value to our corporate structure but more importantly meeting the expectations of our employees. Additionally, Melissa has become a recognized member of our HR team and has become part of the Biodesix culture.

Their deep knowledge of the HR tech space was spot on and are making a difference in our performance. Working with Summit HR and Melissa in particular has really helped us move forward during a time of significant change providing strategic HR services from day one.”
