Meet Our Staff

  • William W. Callahan


    Equal parts mind reader, genius-savant and dynamic problem-solver, Will Callahan is both the figurehead and leader of Callahan & Co. Demonstrating a prodigious talent for anticipating, managing and exceeding client needs and expectations in the Private Client Service realm, Will relies on a vast career of top-level executive communications, team-building and industrial and commercial construction projects. Acknowledging the fact that it may sound like an oxymoron, Will combines the ability to be supremely detail-oriented while also being socially adroit. His leadership and intelligence in coordinating the right individuals for high-end specialty projects reflects these sensibilities and he instills in both clients and co-workers the Callahan & Co. ethos and philosophy. Will’s previous experiences include a 10-year stint in luxury real estate development and construction in Connecticut; marketing of industrial and commercial construction services for JWP, the world’s largest electrical and mechanical contractor; COO of a leading national team building consultant; and founder and president of ImpleMax Equipment Co., Inc, that created and manufactured a new market segment of compact construction equipment for Caterpillar, CASE/New Holland and others.

  • Carlen L. Carney

    CPA, Controller

    A financial virtuoso in every sense of the word, Carlen brings more than 25 years of fiduciary expertise to the team at Callahan & Co. A thorough understanding of accounting processes, organizational redesign, operational goals, information systems implementations and cultural change initiatives inform and direct every decision that Carlen makes on behalf of our very selective clientele. All of which means that she is able to adeptly steer property financials through the complexities of project data, client requests and numeric variances with utter finesse. Carlen’s years of pecuniary expertise include time spent at KPMG Peat Marwick; and roles as Manager of Finance and Reporting, Competitor Analyst and Controller, all at Weyerhaeuser, where she oversaw and was responsible for a worldwide budget in excess of one billion dollars.

  • Terry L. Bridges

    Senior Project Manager

    Combine dedication, experience, operational foresight and engineering acumen and you get a glimpse into the mind of Terry Bridges. As a Project Manager, he balances critical systems analysis against client expectations to define and implement the very best outcomes in a world of constantly changing circumstances. The idea of controlling risk, managing resources and overseeing all aspects of real-time facility operations and trades management while representing unique owners’ interests may seem daunting, but not for a man accustomed to a 24/7 role as the Captain and Chief Engineer of a 400-ton commercial fishing vessel. Terry excels at the tasks mentioned—and numerous others—with a sense of calm and situational awareness that belie the layers of involvement and complexity these take. Terry has more than 30 years of experience in facility engineering, construction, development and operations in fields ranging in diversity from aquaculture to running the back of house as Director of Engineering for a Five Diamond Resort, as well as the aforementioned role on a 400-ton fishing facility.

  • Keith Leenders


    As fanatical about details and follow through as he was about his collegiate football career, Keith Leenders is hands on, to say the very least. Driven by a passion for seeing things through to the last detail, Keith is the kind of Operations Manager that routinely double and triple checks everything, just to ensure that nothing falls through the cracks. He’s not obsessed, but close to it, in the best possible way. A fan of HGTV, Keith regularly stays on top of industry trends in the worlds of architecture, home construction and cutting edge renovation by getting his hands dirty and making sure he understands the intricacies of each and every project from the ground up. His insatiable curiosity and need-to-know attitude fuels his ability to apply critical thinking to even the smallest project-based issue. The newest member of our team, Keith interned with Kiewit Construction, focusing on vendor requisition processes and lien monitoring for industrial projects. Seeking an opportunity at a smaller company where he could be more hands on and assume a wider scope of responsibility, he jumped at the chance to join Callahan & Company.
