cortland addiction treatment staff

Cortland Mathers-Suter, MSSA

Administrative Director

Cortland Mathers-Suter entered the treatment space after his own battle with addiction. He first worked as a peer mentor, before starting clinical work while completing his Masters of Science in social administration from Case Western Reserve University where he focused on policy and direct practice. Cortland moved to Colorado in 2015 to start his first addiction treatment program, AspenRidge Recovery. Under his tenure, AspenRidge Recovery became a two-location, nationally accredited organization. He has since spent the last two years researching and developing what is now Colorado Medication Assisted Recovery (CMAR). According to Cortland, “Colorado Medication Assisted Recovery is the most important organization I have had the honor to help build. We’re offering a service that seeks to not only improve the lives of our patients but also evolve how we look at medication-assisted treatment in Colorado entirely. Most individuals receiving medication-assisted care only receive medication and urinalysis. Sure you can call that ‘treatment,’ but you can’t call that ‘recovery.’ Our model is about adding the missing recovery component, and thus affords an opportunity to achieve lasting change for each patient and the industry.”

Cortland and his treatment programs have received numerous honors. These include Colorado Business Magazine’s “GenXYZ” award, the 2020 “Titan 100” award, and his program AspenRidge Recovery was both a finalist for “Best Healthcare Company” and named in the “Company’s to Watch” by Colorado Business Magazine as well. He has been interviewed and quoted by numerous publications for his “addiction expertise”, including News Week, 5280 Magazine, the Denver Post, Elephant Journal, Colorado Biz Mag, and
