Meet Me!

Hello!

I thought you would like to know a little bit about your ridiculously cool new teacher, so here is some information about me. I am the oldest of 3 children. I have one brother and one sister that I love very much. I am married and have 6 nieces and one nephew on the way! I have 3 pets: a chihuahua named Stosa, a chihuahua terrier mix named Pokey, and a bearded dragon named Jasmine. On my off time I enjoy crafting, painting, building things and playing strategy games. I love math and always have. My passion is teaching; I love witnessing children learn new things. This career brings great satisfaction and I couldn’t imagine my life without it.
