Our Mission

Mockingbird Preschool Kids

The mission of Mockingbird Early Childhood PTO is to connect families and foster relationships between young children, parents, and the school community. The organization hopes to support the neighborhood schools with needed resources and funding to further support our thriving neighborhood.

Our Leadership


Katie Balderston

I'm Katie and I am a momma to George, who is in Kindergarten, and Colin (Entering Kinder in 2023). My husband, Dan, and I knew we loved East Dallas and our neighborhood, but starting this Early Childhood PTO has opened up a whole community to our family that we never knew was right outside of our door. We've enjoyed the new friendships we've made through play dates, parent's night out and organized sports with Mockingbird-bound families. 


When I'm not working on all things ECPTO or chasing my boys, I'm still working with young children! This is my 12th year in education, currently the Director of Curriculum and Professional Development at Saint Michael Episcopal School with past work in the classroom  teaching Pre-K teacher and 3rd grade in HP. Dan works in Wealth Management. We love to travel, watch OU football and sneak in date nights when we can. 

I am excited to see what our organization continues to become in our community and look forward to getting to know you! 


Mary Dryden

Vice President

Hello! I am Mary Dryden and have been honored to serve as a founding member of the Mockingbird Early Childhood PTO. I am a proud mom to Thompson, 5, and Lila, 3, and a proud stepmother to John, 16. My husband, Robert, is a Dallas native and I grew up just down the highway in Fort Worth.


I was drawn to East Dallas after living in Denver for several years. There are few neighborhoods like ours where you can walk to your favorite restaurants, bike to nearby parks, and spend time with friendly neighbors who have a key to your house and not only know your kiddos’ names, but also their birthdays, schools, and friends.


Robert is an engineer at Weidmuller and I am a psychologist. We are excited to get to know you and your family!

Lindsey Siglin


Hello friends!  My name is Lindsey Siglin and I am a mom to Sawyer, 5, and Emory, 2.5, and wife to Joe.  We have lived on Vanderbilt since 2012 and just love our neighborhood!  I am originally from New York and moved to Dallas in 2010 to be closer to my sister.  I have worked in education for the past 15 years.  I previously taught 1st and 3rd grade at Hyer Elementary in Highland Park ISD (with our president Katie), as well as 1st grade in Spencerport, New York.  Most recently, I privately home-schooled a family in University Park for four years.  


Our daughter, Sawyer, is in kindergarten at Mockingbird. Emory will start in 2023.  I now work part-time as a wine consultant for Scout and Cellar, and my husband is a commercial real estate broker for NGKF. We love traveling, checking out new restaurants, being outdoors, and just spending time with family and friends!  I can't wait to get to know you and your family, and bring our community together to support Mockingbird Elementary!
