Robb Holub
Debb Holub

Robb has over thirty years experience in successful start ups and rapidly growing organizations in a variety of industries. Several of those organizations were sold to private equity and one to a publicly traded company.

After learning firsthand the complexities of navigating addiction treatment in 2007, we had a vision of offering a treatment experience and venue for recovery that resulted in successful outcomes for patients and their families.

As founders of Shadow Mountain Recovery, we have dedicated ourselves to fulfilling our mission of helping individuals on the road to recovery. We are grateful to work alongside the team of professionals we have built, who work tirelessly to make our vision a reality.

We have partnered in several successful start-ups, although none have been more rewarding or meaningful than Shadow Mountain Recovery. After 12 years, our passion and commitment remain stronger than ever for helping individuals and their families seeking recovery.
