  Helping people who are often marginalized, stigmatized, or “invisible” has been a calling for me. I have over 15 years of nursing experience, with a background mainly in the emergency room and community practice settings. Providing a safe and non-judgmental space for our patients to establish goals for their recovery drives my motivation. I am honored to work with our diverse patient population and fantastic team every day at Utah Addiction Medicine.  I like to spend my free time outside hiking, skiing, taking photos, and being led on walks by my dog Stella.

I love working with people recovering from alcohol and drug abuse as well as other mental illnesses. Before UAM, I spent time as a front line staff member in an inpatient treatment facility. Now I get to watch people learn, grow, and recover in their day-to-day lives under the care of a stellar medical team.

"If you are needing medication assisted treatment this is the best place." ~Trenton

"From DR., to PA, and staff have always gone just one step further than other programs that I have experience with. They have displayed kindness the likes of which I have never seen. I have 20 plus years in and out of treatment. I wish that wasn't the case. I am grateful for where I have landed." ~Brad

Smart, compassionate, and thorough medical care for people in recovery. I recommend this place 100%. We're lucky to have Dr. Simpson here in UT. ~Daniel

Dr. Simpson has been absolutely wonderful with me and my husband he's been a big part of our recovery and I think he's amazing I would recommend him to anybody. ~Jodie

"There's a saying 'hurt people, hurt people' But I never hear the opposite. 'Healed people, heal people.' Get healed and then go heal." - @theblacksheepsurvives ✨ This man [Dr. Simpson] has dedicated his life to love those that feel unlovable... I’m so glad he is committed to helping others climb their way out of the darkest caves of self-hatred." ~Fesler Films Photography
The staff in this office are the definition of caring addication treatment. They understand the disease, are knowledgeable, and for me personally they have gone out of their way to ensure I get the help I need. ~Michael
