Mrs. Tiffany Grimes

I am a lifelong seeker of knowledge and new experiences who was born, but not raised, in Texas. My oldest son graduated from PSHS in 2017, and my youngest son is a 2019 PSHS graduate. I received a BS in Zoology from Texas Tech University in 1991, and earned my teacher certification in 1996. I have taught multiple scientific subjects since then. In my free time, I enjoy traveling with my family and friends to both exotic and not-so-exotic locales.
