Meet Ten16’s leadership team

Sam has been leading Ten16 since 2003. In that time, Sam and his team has seen the agency grow from three core programs to nine different service lines, and from three locations in two counties to twenty locations across nine counties. Sam has pioneered several programs in the state, including Project Assert in hospital emergency departments, collegiate recovery and Ten16’s unique recovery center model. He is actively involved in state-level policy and advocacy efforts. Experiencing redemption in his own life, he is driven to bring programs that provide people opportunities to change the trajectory of their lives and equip them to find meaning, purpose and connection in their own.

Prior to his work at Ten16, Sam has held leadership positions at agencies in the community mental health system, child welfare, human services and served as a youth pastor. He has two master’s degrees: in religion (Asbury Theological Seminary) and in Marriage & Family Therapy (Michigan State University), and a business degree from Central Michigan University.

Holli Carter came to Ten16 Recovery Network through the criminal justice system. She began as a Probation/Parole Agent. Eventually, she found her way to the intersection of criminal justice and behavioral health as Midland County’s first Human Services Coordinator within the Midland County Jail.

It was in that role that her love for those who struggle with addiction was forged. She joined the Ten16 team in June of 2004 and has been a leader for the Residential Program through 2023.  With her extensive SUD program knowledge, deep commitment to the principles of a recovering lifestyle, and exceptional leadership skills, Holli has transitioned into the Chief Program Officer role.  Guiding and mentoring the Leadership Team, Holli is working to raise up the next generation of Ten16’s leaders who will continue to carry the message of hope and offer a culture of supportive accountability.

She holds a Bachelor of Applied Arts from Central Michigan University as well as Michigan credentials as a Certified Alocohol and Drug Counselor and a Certified Clinical Supervisor.

Laurie Keyser began working at Ten16 back in 1997 when her young family moved to Midland to be closer to her husband’s family. She received my business degree from the University of Michigan and worked in the Detroit area as a CPA for 12 years prior to moving to Midland.

The organization was much smaller when she arrived in 1997, and it has been a great joy to see all the different ways our agency has grown to support those suffering with SUD not only in Midland but across the mid-Michigan region.

Her role is overseeing the financial and human resources functions of Ten16. She is humbled by the difficult work done by Ten16 and honored to be a part of this organization for so long.  Her young family has grown, and her 3 children all work in different cities now, but she and her husband continue to enjoy their life in Midland.

Paul serves clients and staff in his role as the residential manager at Ten16’s residential facility. He has been working in substance use disorder treatment since 2005 and joined Ten16 in 2008. Paul holds master’s degrees in psychology and clinical mental health counseling, and is an LLC, Certified Drug and Alcohol Counselor, and Certified Clinical Supervisor. His dedication to helping others succeed motivates him to “suit up and show up” every day. Above all, Paul values being part of an organization committed to helping individuals realize their potential.
