Brittany Behenna Griffith serves as Lexiam Heart Foundation’s Board President. She found a passion for helping families affected by Congenital Heart Defects after her son, Liam, was diagnosed with several critical heart defects in utero. On May 17, 2015 Brittany and her husband, Brady, experienced the wonderment that came with welcoming their firstborn into the world, and sadly experienced the heart wrenching loss of their son just 21 short hours later. Brittany has made it her mission to keep Liam’s name alive by raising awareness for the 1 in 100 diagnosed with CHD’s and to provide support for New Mexico families and their heart warriors.

It is Brittany’s great joy to be mom to three-year-old, Clara Layne, and newborn son, Preston Kyle, while she continues to hold a most certain hope of one day being reunited with her precious Liam.  She teaches early childhood special education in a classroom of three- and four-year-olds for Santa Fe Public Schools.

Leslee Schneider serves as Lexiam Heart Foundation’s Vice President.  Leslee was born and raised just south of Albuquerque, New Mexico. She attended Texas Tech University with her husband, Jason, and got a degree in early childhood education with an emphasis on bilingual education.  She currently stays home to raise her 3 children: Levi (May 2011), Alexis “Lexi” (September 2013) and Caleb (March 2016).  Lexi was diagnosed at 24 weeks gestation with Hypoplastic Left Heart Syndrome.  The family relocated to Denver for her birth and first surgery.  She has had three open heart surgeries and is officially done with the three required surgeries for HLHS, all done in Denver.  Lexi will eventually need a heart transplant, but as of February 2018 she isn’t listed yet.

Starting the Lexiam Heart Foundation realizes a dream to spread awareness and help other families going through very similar situations to what her family has experienced.  She has always had a passion for helping moms, and helping heart moms is even better.  Together, we can build a strong heart community in New Mexico and spread awareness of CHDs.
