A native of the Greater Boston area, I began my career in commercial real estate in 2015 at CoStar in Washington DC and working in the research department, covering the Indianapolis, Cleveland, and Washington, DC markets. I then transitioned to the institutional sale comps research group and was responsible for preparing sale comps for the Boston/New England markets and worked out of our Richmond, VA office. After working at CoStar for a total of 5.5 years, I relocated to the Greater Philadelphia region and joined Colliers, working in research supporting our Logistics and Transporation Group out of the Conshohocken, PA office. 

In my spare time, I enjoy passionately rooting for every Boston sports team, reading, spending time with family and friends, playing lacrosse and ultimate frisbee, and trying new breweries.
