Chris Williams

Physician Assistant 

Chris is a NCCPA board certified Physican Associate/Assistant (PA) specializing in addiction medicine and psychiatry. He holds his PA degree from MCPHS University in Manchester, New Hampshire, and trained in psychiatry/addiction medicine with the VA Boston Healthcare System in West Roxbury, MA and Providence Recovery Services in Craig, CO. Chris also holds a doctorate in health professions education from A.T. Still University, a master’s in biomedical sciences from the University of Denver, and a bachelor’s degree with pre-med focus from the University of Connecticut. He also holds national certification and state licensure as a Paramedic.
 
His career in addiction medicine started when working as an event medicine paramedic, where he often encountered patients who were intoxicated and strugguling with difficult, substance-related experiences. He quickly realized there was a huge knowledge gap in medical education in this complex field, where patient interactions are often as great a determinant of outcomes as are medical interventions. He subsequently worked to educate not only himself but fellow EMS professionals through formal trainings and presentations at state EMS conferences on interacting with intoxicated patients, handling patients in mental health crises, the role of EMS in combatting the overdose epidemic, and harm reduction practices in the field.
 
After leaving ambulance service, Chris oversaw administration of a federal grant, the Rural Response to the Opioid Epidemic (RROE). RROE initiatives expanded substance use prevention, harm reduction, treatment, and recovery services across five counties in northwestern Colorado. As the program was winding down, he made the decision to further his education and return to bedside medicine by returning to school to obtain his PA license. His intention was always to return to practice in addiction medicine with even more ability to assist and advocate for his patients.
 
Before entering the medical field, Chris served 9 years in the US Navy. Alongside his career, he loves spending time with his wife, Jess, their two Bernese Mountain Dogs, and two cats. He enjoys camping, kayaking, skiing, snowboarding, hiking, motorcycling, and generally most things outdoors. He loves both watching and playing ice hockey, and is known to dabble in electronic music production. Finally, he has never lost his love for event medicine, and still actively attends and provides medical services for major music festivals throughout the year.

Aaron Estrada

Founder and CEO

Aaron was raised in the Lake Tahoe area and was a professional skier competing in Big Mountain competitions. He was the only man to win the U.S. Extreme Freeskiing Championships in Crested Butte, Colorado three times. After surviving a life-altering skiing accident, he became addicted to substances.

The pivotal moment for Estrada came in March 2011. When facing three to five years in prison, a judge offered him a deal of alternate sentencing. While in treatment, he addressed the root of his problems; unresolved traumas. Aaron started working in the substance abuse field shortly after leaving treatment and has worked in many different areas of the field, including Support Staff, Case Manager, and Program Director. This is where his dream evolved. He started to grow a passion of starting his own facility where care could be tailored to each individual, address problems with substances but also heal the mind, body, and spirit while incorporating outdoor activities. That is when Restoration Recovery Center was started.

Since overcoming addiction and finding sobriety, Aaron has found his passion in life in working in the field of substance addiction. Aaron has been working in the field of addiction treatment for over 7 years. Prior to joining the Restoration Recovery Center team, Aaron held management positions at multiple long-term residential facilities in Southern California.
