I am so pleased to begin my 9th year here at St. Gregory’s Preschool! I have been in early education for over nineteen years and I received my Child Development Associate Certification w/ a focus on Preschool in 2008. I started teaching at St. Gregory's in 2011. I became the assistant director in 2014. I am so happy to be able to continue my career in education as the Director here since 2015. I hold both my Texas Director's Credential as well as my National Administrator's Credential. I have been married to my loving hubby for almost 17 years, together we have two beautiful daughters: Gabriella is a junior at Mansfield Early College highschool and Mikaela will begin there as a freshman this year.  I am so grateful for the opportunity to work with you this year as we foster your child's growth in education. I'm looking forward to an outstanding year together with your family!
