Laurie Keyser, BS
Chief Financial Officer / Chief Administrative Officer

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.

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 since.

Christa Galer
Christa Galer, LMSW, CAADC, CCS
Chief Program Officer / Community Engagement Manager (Big Rapids)

Christa Galer started with Ten16 Recovery Network as an “interim manager” for the Big Rapids Outpatient office in September 2009.  She holds a Bachelor of Arts degree from Hope College (1991) and a Masters in Social Work from Michigan State University (1993), as well as holding the MCBAP Certified Advanced Alcohol and Drug Counselor and Certified Clinical Supervisor credentials.  Christa spent many years working with children and families impacted by behavioral health concerns including substance use disorders prior to beginning to specialize her training in substance use disorders until 2006 after the passing of her father from alcoholic cirrhosis.

During her first stint with Ten16 she moved from managing and providing clinical services from the Big Rapids office to eventually managing the programs at the five outpatient locations (at that time).  She took a break in 2015 to work in the Big Rapids community within the primary care setting, hoping to help those with behavioral health concerns (including substance use concerns) to achieve better coordinated health care and to address the stigma surrounding use of substances.

Christa returned to Ten16 Recovery Network, Big Rapids, in October 2020, in a role managing the Big Rapids Outpatient location and part of the leadership team.
