In 2010, he and his wife Francine helped start a girls high school team in Stamford, then co-founded the Connecticut Barons, the first youth hockey program to play out of Norwalk, in 2013.
Now the man of many hats has taken on a new endeavor -- developing a girls program that will be modeled after the Connecticut Oilers, who are in their third season.
The Lady Oilers' teams will begin play next season at the under-14 and under-19 levels in the Eastern Junior Elite Prospect League, the same league in which the Oilers' U-14, U-16 and U-18 boys teams compete.
Serving as the head coach for both clubs will be Melissa Hawkins, who also is in charge of the Wilton-Norwalk-McMahon girls team and coaches a Pee Wee squad for the Barons.
Since she's taking on added responsibility, Hawkins is not sure what her role with the Barons will be next season.
"Melissa and I decided let's go out and try to build a really elite girls program around here," said Ehrlich, the Lady Oilers' general manager. "We're trying to find some of the best girls in the area and we think we can build a pretty good team."
The Lady Oilers complete their inaugural season in the Connecticut Girls Hockey League on Jan. 11, but are switching to the EJEPL because it's a more competitive brand of hockey.
"It's going to be one of the top leagues," said Hawkins, who also is coaching the team in its first season.
"That's why it's going to be really important in the offseason to try to get a good selection of girls to come in for tryouts so we can get that top-notch team."
They will continue to play under the Oilers' banner because of the name recognition and use of the SoNo Ice House as their home rink.
The U-19 girls' EJEPL is Tier 1 with five current teams (Lady Bulldogs, Quakers Hockey, Lady Islanders, New Jersey Rockets and Westchester Wild) while the CGHL is Tier 3 and more recreational.
According to Ehrlich, the closest tier one girls' programs in the area are Mid-Fairfield, which plays out of Shelton, and the Simsbury-based Connecticut Polar Bears.
"The Oilers' name carries a lot of weight and this should be exciting for girls to play for a team where they don't have to travel so far," he said.
Like Eric Lind and Ryan Hughes with the Oilers, Ehrlich and Hawkins will stress skill development with the ultimate goal of getting players into NCAA Division I, Division III and college club programs.
"The best girls have been going to prep school to play," Ehrlich said. "It's the same concept as the Oilers. Instead of paying $50,000 a year to go play prep school, come play for an elite tier one team here and get to play for your high school.
"It's the best of both worlds at the fraction of the cost to play on this high level team. That's why we think we can do it because it'll keep some of the girls home rather than going off to prep school."
The Oilers hierarchy welcomes a girls program with open arms.
"When we envisioned the SoNo Ice House in 2008, we envisioned girls hockey being a huge part of our development," said Ryan Hughes, Oilers President. "The Oilers are looking to grow at all levels and there is a huge demand in the girls market. We hope we can provide the opportunity to girls so they can get to the next level, be it prep school or college or whatever."
The U-19 roster should be comprised of a number of players from the Wilton-Norwalk-McMahon and Stamford-Staples-Westhill high school teams because of the Oilers' ties to those programs.
While Hawkins has an obvious connection to the former, Eli Williams, who coaches the Oilers' U-16 American team, previously guided the Stamford/Staples/Westhill program.
Still, Hawkins wants to cast a wider net and would love to develop a program that is on par with the Polar Bears and Connecticut Ice Cats, a Tier 2 association based in Darien.
"I think next year we're going to try to reach out to a couple other schools," Hawkins said. "I'm going to try to get some New Canaan kids to come and play, kids from Amity up that way, maybe a few kids from the Polar Bears will come down and join us."
Hawkins points to the success of the Darien youth program, where girls join at eight-years-old and stay through high school.
"If we can start to do that here with the Oilers and Barons, I think that would be huge for Norwalk and the girls in general," she said.
The U-14 season will run from September to March while the U-19s will play a half season from August to November with the possibility of added select games later.
According to Ehrlich, the reason for that is because he doesn't want to over-burden players with too much hockey once they re-join their high school teams, though the CIAC does allow dual participation for girls.
Depending on the demand, Ehrlich said the possibility exists of fielding Tier 1 and Tier 3 teams next year.
"With the Oilers' name and Melissa coaching, I think we're going to attract a little bit higher level of talent than we have today," he said. "We will support as many teams as girls who come to play.
"If we have a high level tier one team and a tier three in the CGHL, we're happy to have that at the same age level. We want to support the growth of girls hockey."
The way Ehrlich and Hawkins see it, the more kids playing hockey, whether they be male or female, the better.
