With involvement in over $3 billion of transactions across all asset classes, I have worked with investors of all types including institutional investors, high net worth private clients, developers and financial institutions in South Florida.
Prior to joining Colliers, I served as a Principal of Avison Young and member of its Florida Capital Markets team. Prior to that, I held senior leadership positions with Newmark Knight Frank, Amerivest Group, Savills Studley and JLL.

As a Director, my focus is primarily on investment sales and providing the highest level of service to my clients throughout the South Florida region. I am proficient in valuating assets of all property types and implementing financial analysis through Argus Enterprise and Excel. During my tenure at Colliers international, I have been involved in deals exceeding a combined value of $1 Billion. I have also engaged in select landlord representation, which has only enhanced my experience and ability to fully valuate and transact both income-producing and distressed assets.
My professional accomplishments include researching and analyzing historic and current data for the retail, office and industrial sectors in each submarket and creating individual, detailed reports for all three sectors in the tri-county area of South Florida. I also earned my Argus Enterprise certification to further enhance my skills, while earning my Bachelor’s Degree in International Business from Northwood University in 2015 and my Master of Science in International Real Estate from Florida International University in 2016.
I was born in Munich, Germany, where I have family ties to Colliers International. My family founded the Munich office and I subsequently completed an internship before moving to the USA. My time in the Munich office only made me eager to further my experience in the industry and drove my decision to move to Florida to pursue my degrees, while working in the Palm Beach Gardens office.
