Blake Nichols

Director of Operations

After battling with his own addiction to drugs and alcohol, Blake was given the gift of Recovery at the age of 23. Soon thereafter, Blake altered his career path in order to work in drug and alcohol treatment. Since 2008, Blake has dedicated his life to the addiction field, gaining experience in all aspects of treatment including direct care, admissions and marketing, as well as administration positions. Blake’s greatest reward is being a part of the transformation that occurs when a patient arrives in treatment, and through hard work and the Miracle of recovery, emerges a confident and capable person who is ready to carry the message of recovery.

Katie Riordan

Director of Client Services

Katie was born and raised on Long Island, New York. After moving out to Arizona to begin her journey of recovery, she found that she was able to build such a firm foundation, that she decided to stay. She loves her job working with others in early recovery, and finds it extremely rewarding that she can now use her story to help others battling their own addictions. Katie is currently a student at Arizona State University and is working towards her degree to further her career in helping others.

Erik Shaffer, LISAC

Clinical Director

Since beginning his work in substance abuse and mental health counseling in 1990, Erik is still passionate about what he does. One of our highly qualified members, Erik has a bachelor’s degree in Psychology, a graduate certificate in Substance Abuse Counseling and Pharmacology, as well as a master’s degree in Business Management and Organizational Leadership. He is a Licensed Independent Substance Abuse Counselor (LISAC), specializing in Motivational Interviewing and Cognitive Behavioral Therapy. He has served in numerous leadership positions throughout his career. In 1989, after battling his own demons, he spent the next several years working with troubled youth. He started counseling adults in 1999 after relocating to Arizona, and has never turned back.

While he acknowledges his job can be difficult, with many ups and downs, Erik has always felt drawn to this work and believes that he is helping to make a difference in the lives of others.

Erik has the heart of an artist, originally studying art in college before changing paths to therapy. He still greatly enjoys expressing his art through woodworking, photography, remodeling, and interior design. He also loves the outdoors, travelling, off-roading, riding motorcycles, hiking, and camping when he has the time.

“My biggest payoff for doing this kind of work is seeing the successes; having somebody come back and see us again in six months to say that they are doing well and that we made a difference… we don’t take credit for the work they do, it’s them who do the work, but I like to think we had something to do with it.”

~Erik Shaffer

Tyler Colby

Director of Family Communications

Tyler was born and raised outside Boston, Massachusetts. Since beginning his journey of recovery in 2007, he has pursued different corporate career paths in the banking and insurance industry, but has returned to the behavioral health field where his interpersonal skills and knowledge of addiction are used to educate and inform families during their loved one’s stay at Desert Cove Recovery.

Tyler acts as a liaison between the Clinical Staff, the clients, and the families – helping to provide an insight into the daily lives of your loved ones. Please don’t hesitate to reach out to him at any time.

Libby Felix

Director of Admissions

Libby was born and raised in Chandler, Arizona. After battling with drugs and alcohol, she made the decision to get sober and 17 years old and has been sober ever since. Through the program of recovery, Libby found a passion for helping others experience the benefits of sobriety and starting working in the recovery field in 2015. Currently, Libby is working on obtaining her nursing degree where she can continue to work with people in recovery. Outside of work, Libby spends her time with her husband and enjoys helping other women in recovery.

Zaara Jilani

Financial Controller

Zaara was not the smartest cookie when she stepped on the accounting path. She applied for an Accounts Payable job by mistake and was ironically called for the interview where she was told she “looked intelligent” and was offered the position. She was immensely lucky to work for an amazing and patient Assistant Controller who taught her the basics of accounting and saw the best in her. Since then, Xaara has invested years in education and experience to strive to become better than the 2005 version of herself. After several successful failures of trying to fit in Construction Accounting or working for heartless bosses, her career at Desert Cove Recovery started because she finally figured out that she wants to work at a place of healing and be surrounded by genuinely kind people who love to help and lift others. At Desert Cove, we have all been broken in one way or another and then we have recovered. This is the perfect place for hopeful, helpful and authentic people to work as a team.
