Mark Sims graduated from L.V. Berkner High School in Richardson, Texas, in 1980. He earned an associate degree from Richland Junior College in Dallas in 1982 and a bachelor’s degree from North Texas State University in 1984. In 2001, he completed a master’s degree in educational leadership at Stephen F. Austin State University.

With more than 40 years of experience in education, Mr. Sims began his career in 1985 with Galena Park School District. After earning his master’s degree, he joined Channelview Independent School District in 2001 as an assistant principal at Channelview High School. In April 2005, he was appointed to lead the Endeavor program.

Mr. Sims believes Endeavor provides students with more than the opportunity to earn a high school diploma—it can make a lasting difference in the lives of students, families, and staff throughout the Channelview community. As he puts it, “If we Focus Our Commitment to Unlimited Success (FOCUS), our students will thrive in any endeavor they choose. I want the students at Endeavor High School to believe in themselves, recognize the importance of education, and become productive members of the Channelview area.”

Mr. Sims and his wife, Marsha, have been married for more than 40 years and have two sons, Clay and Reid. For more than 45 years, he has also been involved in local church music ministries and cover bands. He enjoys playing in bands with his son Reid, a guitarist.
