Ms. Sierra St. Valentine
Speech-Language Pathologist for Sam Rosen
I am so excited to be back at Sam Rosen for a 3rd year! I grew up and still live in the small-ish town of Azle, Texas. I graduated from Stephen F. Austin State University (Axe ‘em Jacks!) in 2011 with my Bachelor’s degree and 2014 with my Master’s degree. I enjoy training for triathlons, shopping, dancing and spending time with my husband, Stephen and daughter, Cecilia.

I am the Special Education Inclusion & Resource teacher. This is my 3rd year at Sam Rosen and my 8th year in education. I graduated from Texas Woman’s University with a Bachelors degree in Kinesiology. I live in Fort Worth with my 2 daughters Brooke and Peyton. When they are not keeping me busy, I enjoy working out, reading and going to concerts and sporting events with friends. I’m looking forward to a great year!

Mr. Glenn Omar
Special Education Inclusion Teacher
I am excited to be part of the Sam Rosen Elementary School family. I have been an educator for fifteen years, eleven of those being a Special education teacher and four years as an administrator. I was in the military before I became an educator. I have a bachelor's degree in Aircraft Technology and a master's degree in Education. I am happily married with three beautiful children, and I play the guitar during my spare time. My philosophy of education is “children are individually unique, and a positive stimulating environment is a must in order for them to reach their potential and be productive not only academically, but in life as well.”
I know that Sam Rosen commits to world class education and to a strong partnership with parents and community as it values each student’s potential and character. Truly an excellent place to educate and serve our children.
