Meet our Staff


Marilyn Tolbert, Ed.D.

I am thrilled to be the Director of this wonderful school. I have been in education for the over twenty years – teaching and being an administrator. Prior to my coming to KinderFrogs, I was the Education Director for River Legacy Living Science Center and their Nature School.

Purple blood truly runs through my veins. I received my B.S. in Education, my M.S. in Administration and my Ed.D. in Educational Leadership from Texas Christian University. I have an early childhood endorsement, a Gifted/Talented endorsement and an English as a Second Language endorsement, as well as a Principal certification. I am a member of Kappa Delta Pi (International Honor Society in Education), NAEYC (National Association for the Education of Young Children), ASCD (Association for Supervision and Curriculum Development), DEC (Division of Exceptional Children), ACEI (Association for Childhood Education International), CEC (Council for Exceptional Children) and NSTA (National Science Teachers Association).

I serve on the board of Kauffman Leadership Academy, the board of the Green Oaks School, is past president of the Down Syndrome Partnership of Tarrant County and is on the board and holds the position of First Vice President of the National Down Syndrome Congress. When I am not advocating for and on behalf of children and their families, I love to travel, read, and spend time with family and friends.


Libby Middleton, M.Ed.

Hello! My name is Libby Middleton, and I am honored to be the lead teacher in the toddler classroom at KinderFrogs. I love what a warm and inviting environment this school offers to both families and the university. It is a place where learning occurs on every level, and individuals work together seamlessly to provide high quality instruction.

I have been teaching at KinderFrogs since 2008, and taught in public schools for four years before starting here. I graduated in 2003 from Texas A&M with my degree in Interdisciplinary Studies and in 2011 with my Master’s degree from TCU (Go Frogs!). My husband, Brandon, and I live in Fort Worth with our two girls. We love being a part of the TCU community, and more importantly, the KinderFrogs family. As a teacher, I cherish all the teachable moments that occur throughout our days. I love watching my little friends learn, grow and exceed even the highest expectations.


Kaitlin Kountz, M.Ed.

I am thrilled to be the lead teacher in the Pre-K class at KinderFrogs. I have served in a variety of roles here, including volunteer and KinderFrogs Associate, and I feel like this is where I am meant to be. I know what a truly special place this school is, and what an encouraging environment it provides for all its students and families.

I taught in public schools for two years prior to coming to KinderFrogs, in self-contained classes and co-taught, inclusive Pre-K settings. I graduated from Texas A&M University in 2012 with a degree in Interdisciplinary Studies and in 2014 with my Master’s degree from TCU. My husband Zach and I live in Mansfield with our two dogs. We are both excited to be part of the KinderFrogs family.


Kristen Adams, Ph.D.

I have taught Special Education for eighteen years, both in public and private settings. In 2003 I received my M.Ed. in special education, as well as my administrative certification, from TCU. I have taught in the Toddler and Pre-K classes and am currently in my sixth year with the L.E.A.P. class. My husband James and I have been married for twelve years, have four children, and live in Fort Worth. I am currently pursuing a doctorate in Educational Leadership and feel privileged to be a part of the team here at KinderFrogs.


Vivian Unger

Before coming to KinderFrogs I worked in administration in the public schools in Decatur.  I have been fortunate to have been at KinderFrogs since 2002.  In 2006 I received my Child Care Administrator’s Credential. I continue to be amazed at the wonderful strides we make each day with our students and the support that we provide the families and appreciate the love and the support our families show us. I have been married to my husband for 38 years and I commute from Decatur where we live. We have two grown sons, no grandchildren but looking forward to that day. I love gardening, the beach and hanging out with my friends and family. It is a pleasure serving this school and our wonderful students.
