When it comes to handling students, the teachers, administrators and faculty members at South Huntington school district have a new mantra these days: WWAD, or “What Would Altebrando Do?”

It’s a tribute to a man who, as a physical education and special education teacher and renowned varsity wrestling coach at Walt Whitman High School for the last 15 years, consistently went out of his way to make students and student-athletes’ lives better — particularly the “underdogs” that struggled in and out of school.

Vincent Altebrando was somebody who once bought a tuxedo and prom ticket for a wrestler who came from a broken home and couldn’t afford them, and then dressed in a tuxedo himself, picked up the teenager and chauffeured him to the big event. He was a beloved local whose nine-hour wake service last month drew a crowd of 3,000 people, where hundreds more had to be turned away.

The renowned coach, a Miller Place resident who died April 20 at Stony Brook University Hospital after being diagnosed with HLH, a rare autoimmune disease, at 51, had a big heart and an infectious laugh, an affinity for belting out Beatles songs, and a tough-love competitive spirit that not only put the district on the map athletically, but helped his players beyond the sport. There really was nothing he wouldn’t have done to help his students, according to those closest to him.

“He was always about the kids,” his wife Kristie Altebrando said. “He was always doing things for them. And just when you thought it was enough because his plate was full, he found more room on it. He’s changed a lot of lives.”

Both in school and at home, she pointed out, referring to their four daughters, each of whom compete in sports, from lacrosse to volleyball and field hockey.

“With his attitude, grace, helpfulness and encouragement, it’s all made them who they are,” she said. “I just hope he’s looking down, knowing that while he was alive he was doing all this for people.”

Robin Rose, Walt Whitman’s head varsity football coach and childhood friend of Vincent Altebrando’s, said the wrestling coach had a myriad of accolades. He won the sportsmanship award at this year’s Suffolk County Wrestling Coaches Association ceremony.

 “The best compliment is that Vinny turned athletes into state winners and he helped non-athletes become winners themselves,” Rose said. “He’s a guy this district can’t replace.”

Altebrando also played a large role in launching adaptive physical education and a Special Olympics program for the district’s special needs students.

“It’s an amazing void that he leaves in the school,” fellow Walt Whitman physical education teacher and childhood friend Scott Wolff said. “He was this big, tough, sweet guy; this big center of life in the building and that’s gone now, so we’re all trying to fill a little piece of it — just by building up spirits, being nicer to each other, spending more time with the kids who are struggling. I can already feel the effects.”

Wolff and Altebrando, who was raised by his mother and older brothers after the death of his father at a young age, both went through the Middle Country school system; graduated from Newfield High School a year apart; and were hired at South Huntington Elementary School on the same day in 1994. According to Wolff, Altebrando has been the same since he first met him.

“Vinny was always the best guy to be around — fun, humble and knew how to make everybody feel comfortable and special,” he said.

Terron Robinson, 19, knows that about the coach perhaps better than anybody.

The 2017 Walt Whitman graduate first met his coach as an eighth-grader as a budding wrestler. Robinson said he’d long been cast aside by teachers and other students at school due to his family background — two of his brothers had been to prison, and he thought everybody assumed he’d wind up there as well. He lost his mother at a young age and by the time he was in ninth grade, his father and a brother died, too. It didn’t take long, however, for him to have somebody to turn to.

“In my eyes, that man [Altebrando] was like my father,” said Robinson, who, under the guidance of Altebrando, was a state champion wrestler by 11th-grade. “He saw the good side of me when nobody else did. He was always there for me no matter what. Without him, I’d probably be in a jail cell.”

Altebrando made sure Robinson always had food and clean clothes. He pushed him to do well in school and treat everybody with respect. He took Robinson to the doctor when he was hurt. The coach would even take it upon himself to drive every morning from his home in Miller Place to where his student-athlete lived in Mastic Beach, pick him up and take him to school in South Huntington — where the two of them often worked out together before classes started.

“There was no greater bond I’ve seen between coach and player than the one they had,” Walt Whitman high school athletic director Jim Wright said. “Vinny just saw him as a kid with potential, as a wrestler and also as a person. He brought out the good qualities in Terron and turned him into a citizen.”

Altebrando graduated from Newfield High School in 1984. He was a star athlete on football and wrestling teams, the latter being a somewhat lackluster sport in the district before he came along.

“Then it became an event to go to,” Wolff said, laughing.

Altebrando went to Springfield College in Massachusetts, where he wrestled and received a degree in physical education.

It was during a hectic commute from his first teaching job in Brooklyn that Altebrando bumped into an old familiar face — his future wife — from his high school days.

“We took the train home together and we were engaged within a month,” Kristie Altebrando said. “He was my lifeline, my go-to guy … and it’s overwhelming to see the outpouring of love from so many people for what he’s done and see how many lives he’s touched.”

Natalia Altebrando, 13, a North Country Road middle school student and goalie on a travel lacrosse team, said her father taught her on and off the field how to find courage and strength, and to be kind to others.

“He made such an impact on my life,” she said. “This has broken my heart in a thousand pieces, and the only one who would [normally] be able to fix that for me is him.”

Altebrando’s oldest daughter, Anjelia, 17, will be following in her father’s footsteps and attending Springfield College in the fall.

“He was my role model and really pushed me to work hard for what I want,” she said. “He let me know that anything is possible.”
