Professional Summary

I specialize in all aspects of buying, selling, and leasing commercial real estate. With a background in investment management and commercial construction, I bring a unique and practical advisory approach to each real estate transaction.

Being a part of the Colliers team, coupled with my local market knowledge, gives me access to an extensive amount of resources and collaboration with experienced professionals in every aspect of commercial real estate. This allows me to best serve my clients.

Prior to joining Colliers, I was a sales associate at Cardente Real Estate where I began learning the many facets of transactional brokerage. Before beginning my career in commercial real estate, I was a financial advisor at Royal Bank of Canada and later at James Lamb & Associates, where I managed $100M+ in client assets. Prior to entering the financial industry, I worked with Hanlon Construction (now NH Custom Builder) specializing in the construction and management of residential and commercial projects within southern New Hampshire and a large multi-unit development in Chelsea, Massachusetts.

I hold a bachelor’s degree from Eckerd College in Marketing and Management with a minor in International Business, focusing on Asian markets.

I grew up in Vermont and currently reside in Portland with my wife, Laura.
