Managing Director, Research & Client Services
As the Managing Director, Research & Client Services, I oversee all aspects of our Client Service offerings, including Research, Marketing, Graphics, Financial Analysis, Lease Administration, and Client Service Coordination. I ensure that our brokers are providing superior service and deliverables to existing and potential clients. At the same time, I assist brokers with pitch preparation and delivery, while continuing to push the Colliers brand via best-in-class research reports, thought leadership, and contributions to numerous panels, media, and industry events throughout the city.
I collaborate with every team at our firm and wear many hats: in-house economist, advisor, consultant, thought leader, strategic business analyst, presenter, and, of course, researcher. My team and I manage the information and intelligence in our proprietary database, which, dating from the late 1980s, includes detailed property statistics on nearly 220 million SF of office space as well as on lab properties in the Greater Boston area. We also track more than 150 million SF of industrial properties in our market.
Communication is integral in my work. I write our quarterly Market Viewpoint series, internal submarket and lab reports, and Colliers In Focus thought pieces. I offer market insight as a monthly guest on Bloomberg Radio’s Baystate Business, and I’m a frequent resource for Bisnow, Banker & Tradesman, The Boston Globe, Boston Business Journal, The Real Reporter, and other publications.
Before joining Colliers, I spent 11 years with Property & Portfolio Research (PPR), now CoStar Portfolio Strategy. There, I advised institutional clients on their commercial real estate investment strategies across property sectors and also spoke at industry events, quarterly CoStar webinars, and in front of client audiences. I also led and directed a team of economists who monitored property markets across the United States. Near the end of my tenure, I helped establish a new business unit at CoStar, leading in the hiring, training, and coaching of a team of 50 market analysts.
Outside of the office, I like to cheer on my children’s extracurricular activities. I also hike, travel, relax at home or at the lake, or plug away at one home project or another. Last but not least, I’m an avid fan of Boston sports teams.

Director - Business Development & Content Strategy
In the Director of Marketing role, I work collaboratively on behalf of and alongside representatives from each of our service lines to simultaneously promote the depth of expertise Colliers offers and support teams’ individual and/or collaborative marketing efforts. Building upon a great five-year experience working almost exclusively with the Suburban Brokerage leasing team, I now enjoy ongoing opportunities to cross departments and meet and support my colleagues who bring a wide array of industry expertise. This unique vantage point has given me a strong appreciation and respect for the high level of cooperation, transparency, and camaraderie between groups.
Prior to joining Colliers, I spent four years as an associate with a real estate brokerage firm in Harrisburg, Pennsylvania, working with an elite industrial brokerage team in a true distribution hub market. I developed an interest in and appreciation for supply chain decisions and logistics management, learning that there is much more than meets the eye with what most would perceive as “gritty” warehouse buildings. This experience also afforded me opportunities to learn about different aspects of real estate above and beyond just leasing and disposition, including, but not limited to, property management, development, marketing and research – all invaluable exposure as I now interact with departments within Colliers specializing in each of these disciplines.
In this high energy, competitive industry, I strive to maintain a strong work ethic and calm temperament in my pursuit to provide the highest level of service and support to clients and colleagues. Beyond the office, I enjoy relaxing with family and friends, traveling, and tackling an ever-growing list of home improvements.
