Seymour, a native of Delaware, Ohio, was a three-year member of the Olentangy Liberty High School cross country team and received the Patriot Award from his team as a senior in 2006. His personal best time in a 5-kilometer race was 18:36. A good student in the classroom, Seymour was also a two-year member of National Honor Society.

After graduating from Olentangy Liberty in 2007, Seymour delayed attending college as he chose to serve his country by entering the United State Air Force. For basic training, he went to Lackland Air Force Base in San Antonio, Texas. He graduated from Lackland with honors as he distinguished himself in the top eight percent of over 600 graduates. He also finished 13th out of around 2,000 runners in the 9/11 Run at Lackland as he posted a 19:30 in the 5K race.

From Lackland, Seymour was bussed immediately to Biloxi, Mississippi, to begin his tech school training at Kiesler Air Force Base. During his nine months at Kiesler, he completed the equivalent of an associate’s degree in Ground Radar, Communications, and Electronics. His most significant achievement while at Kiesler was being awarded the Red Rope, which placed him in charge of a squadron of over 600 airmen. He was given special honors by a Chief Master Sergeant, a Lieutenant Colonel, and a Brigadier General during his year of training and also had the honor of being selected to escort Brigadier General Moss during the Veterans’ Day Parade at Kiesler. During his time at MVNU, he will be promoted from Senior Airman (E4) to Staff Sergeant.

"Jameson is a dedicated and hard-working athlete who will be a great fit for our young program,” said MVNU head coach Chip Wilson. "I recruited him out of high school a year ago, but he decided to serve our country. He was a strong runner in high school and his year in the military should prove to help make him an even stronger physical runner as well as a stronger mental runner. He is joining a great group of guys who know how to prepare for an 8-kilometer race, and his work ethic will fit well into our program. I look for him to have a strong freshman year.”

"There are several reasons why I chose MVNU,” said Seymour of his college choice. "I wanted to run cross country and I like the Christian atmosphere. I have a lot of friends already there and plan to meet new ones. I am away from home, but still pretty close. I also plan on majoring in two majors that MVNU has to offer (Business Administration and Criminal Justice), and I look forward to all the professors there.”

The MVNU cross country program was reborn in the fall of 2006 after not having a program since the 1979 season. After a competitive first season back, the Cougars continued to improve in 2007 by finishing sixth out of 12 teams in the American Mideast Conference/NAIA Region IX race and tenth out of 22 at the National Christian College Athletic Association meet.
