Amber Freeman - Principal
My name is Amber Freeman and I am the proud principal of Dr. Winn Murnin Elementary School. I began my education here in Northside, attending Locke Hill Elementary and William P. Hobby Middle School. I graduated from Floresville High School and attended The University of Texas at San Antonio. I earned a Bachelor of Arts Degree in Interdisciplinary Studies and a Master of Arts Degree in Education from U.T.S.A.

I began my teaching career at Paul W. Ott Elementary School. I taught 4th grade for six wonderful years before moving into administration. I served as the Vice Principal at W.Z. Doc Burke Elementary for five years. Since 2015, I have had the privilege of serving as the Principal of Murnin Elementary.

I live in Northside and have two boys who attend Northside schools. My husband also works in Northside as a Head Boys Coach. We feel blessed to be part of such a great community.

I look forward to building relationships with all of our students, parents, staff and community. At Murnin Elementary, we believe all students can and will learn at high levels.

Please feel free to contact me if you have any questions, concerns or comments.

My name is Laura Sheffield and I am the Associate Principal of Murnin Elementary. I attended The University of Texas at San Antonio, where I earned my Bachelor's degree in Interdisciplinary Studies and my Masters degree in Educational Leadership.

I was fortunate enough to be a part of the Murnin family when it first opened in 2006. I taught third grade for fourteen years. I was a Math Specialist and instructional coach during my last year at Murnin. In 2002, I left Murnin to work in Central Office in the Office of Teaching and Learning. I am so grateful that I was able to come back to Murnin this year as the Associate Principal.

I look forward to reconnecting with staff, families and our Murnin community. I truly believe that Murnin is a great campus and it is what brought me back. I have three children and all of them have attended Murnin and still remember this as being a great school. I am excited for the new adventure and the school year!

Please do not hesitate to reach out with any questions you may have.
