Bryan F. Read, a longtime Dulaney High School athletic trainer who was known and respected by coaches and athletic directors throughout Maryland, died Tuesday from colon cancer at the Gilchrist Center in Towson. The Parkville resident was 36.

“The word I use to describe Brian is pro. He was a real pro,” said Brian M. Perez, operations manager and head athletic trainer for the University of Maryland’s Towson Sports Medicine, who was Mr. Read’s supervisor and employer.

“I had complete faith in Bryan’s operation at Dulaney, where he had been a rock star for 12 years. Dulaney was his element. It was his world. He did everything to serve the school, community, and the kids,” said Mr. Perez, a Parkville resident.

Richard “Rich” Reed, athletic director at Dulaney, worked very closely with Mr. Read.

“This is a tough one because Bryan was beloved,” Mr. Reed said. “There isn’t a coach or student that hasn’t been affected by this loss. He was the utmost professional every day and was the most diligent person I’ve ever known in my life. We have a huge void to fill right now.”

Bryan Fulton Read, the son of Robert C. Read, an actuary, and his former wife, Mary Elizabeth “Chip” Rouse, an associate professor of business communication at Stevenson University, was born in and raised in Towson.

Mr. Read graduated in 2002 from St. Paul’s School in Brooklandville, where he was an outstanding athlete, playing basketball, football and lacrosse.

He continued playing lacrosse at Hofstra University, where he studied athletic training as a Provost’s Scholar. When he earned his bachelor’s degree in 2006, he was named Outstanding Student Athletic Trainer and was the recipient of the NCAA Colonial Athletic Association Commissioner’s Award.

While earning a master’s degree in athletic training from the University of Virginia, he served as graduate assistant athletic trainer at Fork Union Military Academy in Fork Union, Virginia.

After graduating from Virginia in 2007, he accepted a job from Towson Sports Medicine and was assigned to Dulaney, where he remained working until his death.

“The graduate level program at Virginia is probably the premier program in the country,” Mr. Perez said. “He was Dulaney’s athletic trainer for a very long time, and for a lot of people, he was synonymous with Dulaney.”

While at Dulaney, he was concurrently an athletic trainer for the old Crystal Palace football club at the University of Maryland, Baltimore County, Elite Tournaments, Breakers Club Lacrosse, Cal Ripken Senior Baseball League and Caringi Soccer Camps during the summer.

At Dulaney, Mr. Read provided athletic training services and medical coverage yearly for a 45-team program with approximately 700 athletes. He also regularly taught care and prevention of athletic injuries and cardiopulmonary resuscitation for Baltimore County coaches’ certification.

“Bryan was a veteran when it came to athletic training throughout the county and state. So many relied upon his opinions and teaching,” said Mr. Reed, a Hampden resident. “He was a major part of the athletic program in Baltimore County. Hundreds of coaches have come through his training. It’s a testament to his teaching and work.”

“Bryan spent so much time with his teams and was always the last one off the field and the guy who closed the gym,” his mother said.

“He was a teacher and a front-line coach, and the kids always felt they were in good hands when Bryan was around,” Mr. Reed said.

“We didn’t realize how much he did for us until he got sick,” Mr. Perez said. “If we needed something done, he was the first guy to put up his hand and then he’d grind it out. He took a lot of pride in his work and he was a valuable person to have on your staff. We got along well because our personalities fit each other’s.”

Mr. Perez described Mr. Read as a “quiet and private person who had a wonderful dry sense of humor.”

After being diagnosed in February 2018, with the cancer that eventually claimed his life, he returned to work.

“Bryan eased himself back into work. He’d go for a radiation treatment at St. Joe’s and then would go back to work at Dulaney,” Mr. Perez said. “He wanted things to keep going. He fought really hard, and like some people in his situation, never said ‘I’m done.’ He was tough as nails and wanted to serve his kids. And whenever you asked how he was doing, he’d say, ‘I’m OK.’ ”

“After the diagnosis, he continued to work despite the pain and treatment,” said an uncle, Alfred W. Barry III of Homeland.

A scholarship for a graduating senior athlete at Dulaney was established in Mr. Read’s name in 2018, and the first award was presented this year.

“We started a scholarship in his honor last year, and he was very proud of that,” Mr. Reed said. “We will continue to honor Bryan that way.”

Because of the nature of his work, his mother said, he didn’t have a lot of time for hobbies, but he was an inveterate Orioles and Ravens fan.

A Mass of Christian burial will be offered at 11 a.m. Friday at St. Joseph Roman Catholic Church, 101 Church Lane, Cockeysville.

Mr. Read is survived by his mother, of Lutherville, his father and stepmother, Clare Read, of Ellicott City; and many aunts, uncles and cousins. An earlier marriage ended in divorce.
