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.


After serving as an Advocate for a number of years, Susan joined the CASA staff as a Case Supervisor in January 2019 and was promoted to Assistant Program Director in March 2022 and took over as Program Director in May 2023. She first became aware of CASA while working for the British Consulate in Houston where she provided consular services to British families, some of whom had children involved in the child welfare system and were appointed CASA Advocates. After leaving the British Diplomatic Service, Susan was drawn to the field of child advocacy. She believes passionately in CASA’s vision and mission, and she appreciates the opportunity to make a positive impact within our community, one child at a time. Susan earned a BSc Econ (Hons) in European Studies with French from the University of Wales, Aberystwyth (United Kingdom), from the Department of International Studies. She is a TBRI Practitioner and on the LGBTQ+ Committee. Susan holds nine Queen’s Commissions for each of her Consular appointments overseas in Central and South America, all of which are personally signed by Her Majesty Queen Elizabeth II. Susan and her husband, Andy, love traveling, sailing, and classic Fiats and are members of the Lake Conroe Sailing Association and the Fiat Club America. She also never misses a chance to see a Broadway show. They live in Spring with their boxer, Maia.

Mandy DaltonMandy Dalton

Mandy is an Assistant Program Director and came to CASA in 2012 after working a little over two years with Child Protective Services in Montgomery County. Mandy’s vast knowledge of the CPS system has been exceptionally beneficial to our CASA program. It is very important to Mandy that she is able to work in a program where she can make a difference. Mandy earned her associate’s degree in 2007 from Tomball College (now Lone Star College), her Bachelor’s degree in Criminal Justice in 2009 from Sam Houston State University, and her Master’s in Administration of Justice and Security from the University of Phoenix in July 2011.

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). Her grown daughter, Madison, lives in North Carolina and is pursuing her fitness career.

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.
