IOP Program

At Colorado Medication-Assisted Recovery (CMAR), our Intensive Outpatient Program (IOP) provides a structured yet flexible approach to addiction treatment.

Located in Denver, Colorado, our IOP is ideal for individuals seeking comprehensive care while maintaining work, school, or family responsibilities. Our evidence-based treatment methods help individuals overcome substance use disorders with personalized support.

 

What is an Intensive Outpatient Program (IOP)?

An IOP is a step down from inpatient rehab or a Partial Hospitalization Program (PHP) and offers a balance between structured therapy and daily life responsibilities. This program allows individuals to receive intensive addiction treatment while still living at home or in a sober living environment.

CMAR’s IOP includes three to five days of treatment per week, with three-hour therapy sessions per day, focusing on skill-building, relapse prevention, and mental health support.

 

Key Features of Our IOP in Colorado

  • Personalized Treatment Plans: Each client receives a customized care plan to address their specific addiction and mental health needs.
  • Medication-Assisted Treatment (MAT): We offer FDA-approved medications such as Suboxone, Vivitrol, and Sublocade to reduce cravings and prevent relapse.
  • Group Therapy Sessions: Our IOP includes structured group therapy, offering peer support and skill-building through evidence-based approaches like cognitive-behavioral therapy (CBT) and dialectical behavior therapy (DBT).
  • One-on-One Counseling : Clients receive weekly individual therapy sessions to explore personal struggles and create strategies for lasting recovery.
  • Mental Health & Dual Diagnosis Treatment: Many individuals face co-occurring mental health disorders, and our program integrates addiction and mental health care for comprehensive recovery.
  • Case Management & Life Skills Coaching: We provide relapse prevention planning, job readiness, and life skills training to help individuals build a sustainable future.
  • Family Involvement & Support: Families play a crucial role in recovery, and we offer family therapy and education to strengthen relationships and communication.
  • Flexible Treatment in Denver: Our morning and evening IOP sessions allow clients to maintain their daily routines while receiving high-quality care.

Like so many others… unfortunately, after having 13 years clean I had a hand surgery and opened up the doorway to a relapse… Luckily, it was only a couple months before making the decision to change my life once again…I found my way in to CMAR, which is medication assisted recovery… but beyond that, they do so much more after getting past that, the level of professionalism that you receive from the counselors, and everybody on staff is amazing! I was in multiple programs years ago…. Nothing compares to this one! CMAR has saved my life!

I have been to other iop programs and this is the only program that keeps my interest and is NOT boring. On Fridays we engage in art/music therapy or watch a movie, for example pixar’s Inside Out. I truly look forward to going and I am going to miss the staff and clients when I graduate. CMAR makes recovery fun!!

In order for me to live a genuine life, I must be abstinent from alcohol. The pleasures of substance use disorder had left me with a DWAI, DUI, and many years of court ordered programs. This includes years of probation, ordered UA screenings, and countless hours of community service. Also, a handful of destroyed relationships, countless moments of remorse, and thousands, if not, hundreds of thousands of dollars. Who knows…Nothing would stand in my way of a drink. My actions revolved around minimizing consequences to decisions that would reap the best benefit of this disorder. This disease manipulates you and as a result, you manipulate everyone around you just to fulfill a falsely created ritual.After spending another round in rehab, I started an intensive outpatient program at CMAR. I recently graduated and started in their regular outpatient program. I get to see a certified counselor every week in addition to fixed flexible courses. This place saved my life. I don’t take that lightly and I’m not exercising my freedom of speech just to say it. I mean it, CMAR’s professional staff and programs saved my life.I just hit the 7 month mark of my sobriety. I’m happy, in every sense of the word, in a way that I haven’t been in many years. For anyone out there struggling, please recognize, I know exactly what you’re going through. I’m not unique in any way. I just decided that my life is worth living without substances.I believe that taking your first step to accepting this truth is going to be the hardest. Please consider allowing CMAR to help you ground this decision. It’s the most important choice you’ll ever make. The road to recovery is not an easy one. The greatest part of all the difficulty is that we’re not alone. CMAR develops serious relationships with others through intense attributable work.Since this is working for me, I have no doubt in my heart that it will work for you. Please take action because it’s already too late. For a lot of people, they never got to this realization. I hope to see you soon in one of the classes.Peace and grace be with you,Jeremiah White

I can’t say enough about CMAR. Their responsiveness in a time of need made all the difference in the world. The groups are scheduled so that outpatient therapy is convenient. The group therapy is invaluable. The staff is approachable, and relates exceptionally well to their clients. Highly recommend.

I was fortunate enough to have the opportunity to work with Michael and his team at CMAR. They provide exceptional, patient-centered care and are a wonderful community resource when it comes to state-of-the-art addiction treatment. They provide an integrative and evidenced based approach to addiction treatment; above all, they truly care about each individual patient. You can’t go wrong putting your trust in CMAR. I highly recommend!!

Cortland Mathers-Suter

MSSA
Managing Partner

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 TheRecoverySource.org.

After seven years, Kirstin made a career change to diagnostic sales and worked for several Fortune 500 companies as an acute care sales specialist. She is delighted to return “home” to her passion for helping others and believes her new role as community engagement coordinator for CMAR is the perfect alignment of both her clinical and sales skills.
