Ann Marie RonsmanAnn Marie Ronsman

Ann Marie became the President & CEO of CASA Child Advocates of Montgomery County in February 2021. She first joined CASA as a volunteer Advocate in 2014. Ann Marie took on the role of CASA Training Director in early 2018. A Trust-Based Relational Intervention® Practitioner, she has grown CASA’s partnership with the Karyn Purvis Institute of Child Development at Texas Christian University and is leader in the implementation of TBRI® within the child welfare system. She has spearheaded many CASA initiatives, including Trust-Based Relational Intervention® (TBRI®) education for CPS, the Montgomery County District Attorney’s office, and numerous other community organizations.

Ann Marie is well known in Montgomery and Harris Counties as an expert on the impact of childhood trauma, with a passion for the mission of CASA to positively impact children’s lives in the foster care system. Ann Marie is the co-chair of the Trauma-Informed Montgomery County Task Force, which promotes a county where the community recognizes and understands how to best respond to children who have experienced trauma.

She is a member of the Leadership Montgomery County class of 2022. She earned a Bachelor’s degree in Nursing from Marquette University, Milwaukee; Master’s in Nursing from Cardinal Stritch University, Milwaukee; and a certificate of Non-Profit Leadership from the University of Texas. Ann Marie and her husband, Matt, live with their five children (three of whom are adopted) in Montgomery. She is a native Wisconsinite and a huge Green Bay Packer fan. They keep very busy with sports practices, homework, and laundry. Ann Marie and Matt have led adoption and foster care ministries for many years. In her spare time (what is that?) she enjoys reading, gardening and travel. Her family also fosters Basset Hounds for Basset Buddies Rescue of Texas as well as dogs for Who Rescued Who. They’ve fostered over fifty dogs so far.

Her roles ranged from customer service associate and manager to operations analyst and health and welfare client manager. Julie was exposed to CASA through a work-related event and became an Advocate in 2013. She was drawn to children in need of a voice and knowing her daughter would be graduating from high school, felt it was time to lend a hand. Julie brings strong communication and project management skills to her role, along with a love of interacting with various people, learning new tools, and directly helping the community. Julie is originally from New York and attended Rochester Institute of Technology (RIT). She is also on the path to completing a Child Yoga Teacher certification program.

She has worked directly with foster and adoptive families, in addition to children living in residential care. She is also a TBRI® Practitioner and was previously licensed as a Child Care Administrator and Child Placing Agency Administrator.

She believes in the mission and all the work being accomplished by Child Advocates of Montgomery County. Camille holds a Bachelor’s Degree in Psychology from St. Edwards University in Austin, Texas, and a Master’s Degree in Social Work from Our Lady of the Lake University in San Antonio, Texas.

After serving as an Advocate since 2018, Allison joined the CASA staff as a Case Supervisor in February 2022. Allison had been drawn to CASA for years but had never fully taken the plunge. It wasn’t until, as fate would have it, she had an unplanned encounter with a CASA recruiter while attending jury duty. It took just one visit and a half-cup of coffee over lunch to put her on the path of being an Advocate, taking her first case in 2018. Allison brings to CASA an energy that has served her well in both her personal and professional career. She’s spent the majority of her career in the “big box” retail sectors and successfully managed numerous people, teams, and projects across Texas and Louisiana.
