Mrs. Shaina Costello


I was born in Bridgeton, Missouri. I graduated from Pattonville High School in 2003. I earned my Early Childhood Education degree from Webster University in 2007. I was a student athlete (and still have a slightly competitive side). I learned the importance of organization and multitasking, to keep up with the endless demands of being a full time student and athlete.

I love my family and friends! You can catch us BBQ-ing, playing yard games, camping, exploring the Zoo, or searching for the best ice cream in town, just about every weekend that the weather will allow. I have an 11 year old dog named Cash, my husband and I will be married 6 years this September, and we have a 3 year old boy and 6 month old girl. I am always looking for opportunities to make memories with my little family.

I started working in the field of education as a substitute teacher. I later took a position as a teacher's assistant, and then a specialized support staff, focused on the areas of math and reading intervention. During the 2011-2012 school year, I became part of the Hamilton family! #HamFam  

In 2015 I decided to pursue some of my own educational goals and jumped back into a desk at Webster University.  In 2018 graduated with a Master's Degree in Reading and Literacy, and Missouri Reading Specialist Certificate.
