Ron Dock exited the Yankees’ world this past week the same silent way he entered it in 1998.

If the name doesn’t sound familiar, it shouldn’t. As the organization’s intervention coordinator based in Tampa, Fla., Dock worked in the shadows and often underground, helping Yankees employees with addiction problems, family situations, depression and legal issues.

“It was my choice, time to move on. I went to Brian Cashman and thanked him and he gave me a hug. There are no regrets, I left on a high note,’’ said the 65-year-old native of The Bronx, who attended Evander Childs.

As an 18-year-old, he landed in Vietnam, where he was introduced to smoking heroin that was taken off dead Viet Cong soldiers.

“Then it was marijuana and alcohol until October 5, 1992,” he said.

Three years later, Dock met Dwight Gooden at a Narcotics Anonymous meeting in St. Petersburg, Fla. Three years later, Gooden introduced Dock to minor league head Mark Newman, who hired Dock after asking if he could help a minor leaguer with a major drug problem.

“He did a lot for a lot of players, coaches and families,’’ Newman said of Dock. “He is one of the most selfless people I have met in and out of baseball.’’

Cashman noted Dock’s knack for being always available.

“He is a caring and giving individual,’’ Cashman said. “He is someone who in difficult times was always there to help and support our players and employees.’’

Darryl Strawberry benefitted from Dock’s attention during Strawberry’s time with the Yankees, which ended in a drug suspension during spring training in 2000.

“He was very valuable for a lot of people. He saved young players from destroying their careers,’’ said Strawberry, who employs Dock in his two treatment centers in Orlando and Daytona. “He helped me out a lot.’’

Ray Negron, who was involved in Strawberry’s and Gooden’s recovery program when Dock arrived, praised him.

“He was the right guy at the right time,’’ Negron said. “He took Darryl and Doc to the next level. I was the Band-Aid, he was the surgeon.’’

Damon Oppenheimer, as the Yankees’ director of amateur scouting with an office in the minor league complex, had a front-row seat for Dock’s program.

“He was always available to help our guys out and a lot of our players benefitted from his caring and the time he spent with them,’’ Oppenheimer said. “He helped a lot of them get over the hump.’’

Outfielder Slade Heathcott often credits Dock for helping him escape the hell of addiction as a minor leaguer. However, not all of Dock’s work dealt with drunks and drug addicts.

“Kids were homesick, depressed, hurt, coaches and employees had problems that weren’t related to addiction,’’ Dock said. “Maybe 5 percent of it was working with substance abuse.’’
