Leadership Team 


Tim McMahon

Founder/Executive Director

Tim McMahon is the Founder and Executive Director of Brightstone Transitions. Tim has a Bachelor’s degree from the University of North Georgia, and has been working in the field of therapeutic programming for over 20 years. He has helped design and implement residential, therapeutic, and academic programs across the country. Tim is married with two children. When not at work, he enjoys spending time outdoors with his two daughters.

While managing 10 intensive residential treatment programs located in 6 different states across the country, Tim began to realize that there was need for resources to help young adults who, despite therapeutic intervention, needed support to move forward. These young adults appeared stuck, and were often unable to make plans that allowed them to advance. These young adults needed guidance, but often did not respond to the traditional clinical interventions. It was out of Tim’s passion for helping these untraditional young adults that Brightstone Transitions was born.

Tim has a hands-on approach to running Brightstone. Tim believes that the key to reaching these young adults is through persona relationships. With that in mind, Tim designed Brightstone to be a very small and very individualized program.

Tim brings a wealth of experience and personal knowledge to Brightstone which he uses to help his clients and families build a foundation for success. He helps clients to define clear goals and develop plans to work toward those goals. Tim believes in an action oriented approach that moves clients beyond the classroom and into real life experience.

Curtis Foster

Program Director

While studying psychology in college, Curtis obtained a job at a private psychiatric hospital in the Oklahoma City area working on the adolescent units. Curtis moved from this level of care to a new residential treatment center that had opened with 17 beds. Curtis stayed with this organization for 14+ years and helped it grow from 17 beds to 72 beds with a fully free-standing psychiatric hospital unit. Within this time frame, Curtis helped develop programming for the organization, trained staff in crisis intervention strategies and ROPES course instruction and managed the mental health workers as well as the ROPES course.

Having grown up in the west Texas town of El Paso, in the desert southwest, Curtis always wanted to live in a mountain environment. In 1997, he got that opportunity by moving to far north Idaho to work as a Team Leader in a therapeutic boarding school. Curtis continued to gain experience over the next 15 years working at two different schools in the same area. After this he spent two years working as a Program Director for a wilderness therapy program in southern Idaho.

Curtis and his wife have three grown children who lived most their lives in Sandpoint, Idaho. All three kids are now out of the home, in college, or out in the world starting their independent lives. Curtis is happy to be grandparents as well. Curtis and his wife both love to run, camp and hike, and we enjoy college sports. You can often find them running out on lonely roads, trails or in regional racing events where we often meet up with our extended family who also love running.
