Keith Caldwell’s name went onto a draft list long before it went onto an executive biography. In January 2006, the Colorado Rapids selected the Brown University forward and midfielder with the 33rd pick in the MLS Supplemental Draft. A young player from Braintree, Massachusetts, had a chance to make a professional roster. It was an invitation to prove himself all over again.
Twenty years later, Caldwell leads H2O Care Partners, a Boston-based network of local water treatment businesses. The connection between those jobs is less obvious than a business biography might like. One involves a ball, the other acquisitions, payroll and service appointments. Yet both raise a question that follows Caldwell through his career: what happens when capable people get the support to work together?
His current company has a particular answer. Buy into established businesses. Help with the machinery of running them. Keep their local identities. For a chief executive, it is an interesting exercise in restraint. Getting bigger usually supplies plenty of opportunities to put your own name on things. Caldwell’s business depends on the value of names that were there before he arrived.
The phone call from Colorado
At Brown, Caldwell played for Mike Noonan. His 2004 season included five goals and two assists, enough to tie him for second on the team in scoring. He received All-Ivy honorable mention, then received the distinction again as a senior. The record is of a productive college player, with the goals and recognition to explain why a professional club would take a look.
The draft still caught him by surprise. “It was a great surprise,” he said at the time. He had spoken with the Rapids, but a conversation and a selection are different things. On January 26, Colorado picked him in the third round. By the following Monday, he was in Colorado, preparing for a two-week training camp and a decision about whether he would stay.
He did not make the Rapids’ roster. That detail matters. Being drafted can harden into a convenient piece of executive shorthand, suggesting a professional playing career with its awkward edges removed. Caldwell had earned the opportunity; the opportunity did not become a place on the team. His soccer story continued anyway, in coaching, competitive play and eventually the business of the sport.
There was plenty of soccer around him. His father, Larry, had played for the Hartford Bicentennials. His younger brother Scott would play for the New England Revolution, and his sisters Amy and Andrea played in college. Keith became a mentor to Scott. In that household, a conversation about the game could have required a fairly generous dinner table.
Still finding the net
Soccer did not become merely an anecdote for Caldwell to tell in meetings. In 2016, playing for GPS Omens, he scored 20 goals and led the Bay State Soccer League in scoring as the team won the title. In May 2017, he scored the opening goal when Omens beat Boston City 2-1 in the U.S. Open Cup. That summer, he joined Boston City himself.
The club’s account records a wonderfully specific contribution: one appearance, a start, 55 minutes in a 2-0 home win over Kingston Stockade at the end of the regular season. There is something pleasing about that level of precision beside the broad claims of an executive résumé. Fifty-five minutes is a contribution you can picture. It also establishes that Caldwell was still competing, rather than simply dining out on a draft selection from eleven years earlier.
He had also moved into coaching. As director of coaching at Scorpions Soccer Club, he helped guide the program to a Soccer America top-20 national girls’ club ranking. Samantha Mewis, who went on to win the World Cup with the United States, was among the players he helped develop. The work extended his relationship with the sport from his own performance to other people’s progress.
A bigger playing field
Caldwell earned a B.A. from Brown and an MBA from the University of Michigan. At Boston Consulting Group, he became a project leader and worked on strategy with sports organizations. His assignments included supporting the United Bid Committee for the United States, Canada and Mexico in its successful bid for the 2026 FIFA World Cup.
A tournament bid is a different sort of team effort from a college match. Countries, cities and organizations have to assemble a shared proposal. Caldwell’s place in that work gives his career an unusual scale: the same biography contains a local club’s 55-minute appearance and a consulting assignment connected to a three-country tournament. The contrast makes the career more interesting than a tidy sequence of promotions.
In January 2020, he became CEO of Global Premier Soccer, responsible for its business operations and strategic initiatives. “My entire life has revolved around soccer,” he said on taking the job. Here was a role that joined his playing and coaching background with his business training. The appeal was easy to understand.
The tenure had a difficult ending. In June 2020, Caldwell confirmed that Global Premier Soccer would close and that Chapter 7 bankruptcy proceedings were expected. Parent company Legacy Global Sports had made the decision. The appointment and the closure belong in the same career account. A title can describe responsibility without supplying a happy ending, and a short tenure should not be polished into a success story it cannot support.
A company with a name worth keeping
The next chapter began with an established Massachusetts business. In 2021, Caldwell met Mark St. Hilaire, the founder of H2O Care. A year later, Shore Capital Partners announced the formation of H2O Care Partners and its first strategic partnership with St. Hilaire’s company in Middleton. H2O Care also had locations in Stow and Lakeville.
This was a business with a history of its own. The team had been operating since 1989 and had more than 12,000 filtration and softener systems installed across New England by the time of the announcement. St. Hilaire would remain president. Caldwell would lead the new organization, with David Trompke and Eric Handsman among its founding team members.
The distinction between the two companies is useful. H2O Care supplied an existing operating business, local relationships and years of work. H2O Care Partners supplied a structure for adding resources and bringing other businesses into a network. Caldwell was helping build a new organization around something that already worked. The starting point called for curiosity about an operator’s business, along with an acquisition agreement.
“Our goal is to build on that versus take anything away.”

The practical appeal of fewer chores
The support offered by Caldwell’s company is quite concrete: accounting, payroll, recruiting, training, marketing, technology and capital for expansion. These are ordinary business needs, which is precisely why they matter. A founder can care deeply about customers and still spend an afternoon sorting out administrative work. Enthusiasm for the trade does not automatically confer enthusiasm for every task required to run a company.
Consider Alamo Water Softeners. Its leader, Trevor Townsend, wanted help growing the business and creating opportunities for his team. Within the first month of the partnership, the sales team had a fleet of vehicles. Townsend had considered that a longer-term ambition. A fleet makes the promise of financial support rather more tangible than a slide describing it.
Or consider Jamie Reynolds at Reynolds Water Conditioning in Michigan. He was approaching retirement without an identified successor. He met Caldwell, the two got along, and Reynolds chose a partnership intended to let the team carry on after he stepped away. The question in that case concerned continuity: who would help the business keep going when its owner was ready to stop?
Rob and Sue Frey of Guthrie & Frey approached the prospect with questions of their own. They wanted the opportunity to improve the business within a group focused on their industry, while easing the burden of being responsible for everything. These examples help explain Caldwell’s role. He has to make a partnership useful to people whose ambitions, timetables and attachment to their companies differ.

Thirty-four partnerships, many local histories
By September 18, 2026, H2O Care Partners had completed 34 partnerships and operated across 20 states. Its latest announcement described additions in Washington, Michigan, the Southwest and Florida. American Pump & Drilling brought well drilling and pump services; Beauchamp brought a Michigan family’s long involvement in the trade; Universal and Superior operated across several western states.
The company also appeared on the Inc. 5000 for a third consecutive year in 2026, at number 402. Caldwell holds a board seat at Alliance Markets & Vending as well. These are markers of the scope of his present work. They do not eliminate the everyday challenge underneath it: keeping an expanding organization useful to each business that joins.
Caldwell has described his ambition as making H2O Care Partners an employer of choice in its industry. It is an ambition that fits the recurring subject of his career: people finding a place on a team, and finding room to develop once they get there. His own route took him through a draft camp, coaching, consulting and a difficult CEO assignment before this one.
For the local founders now working with him, the test is closer to home. Does the support arrive? Can the team keep serving its customers? Can the business continue beyond its founder, or grow beyond what the founder could manage alone? Caldwell’s next chapter will be written in those answers, under a collection of names he did not invent.
