Mark von der Burg, the Founder of VDB Compass and the Founding Broker of Compass Seattle, has built a reputation on expertise, innovation, and commitment, earning him the respect and admiration of clients and fellow Realtors alike. They fondly refer to him as “Uncle Mark.” A fierce competitor and faithful advocate, with a confident, steady manner, Mark’s success lies in his ability to read a target audience, interpret market data, foresee emerging trends, and respond appropriately. He is especially skilled at preparing and marketing the perfect home and negotiating the impossible deal, earning the highest rate of return for his clients. Their success and his family are his pride and joy. 

The VDB Team is an impressive group of established professionals who have proven their ability to get the job done. 

The entire broker team, including Brokers Erin Harper and Porter Balke, are longtime PNW residents specializing in local luxury markets. Erin is a leader in her field and the community. Her business savvy, solution-driven approach and dedication to success have earned her clients’ trust and a reputation for achieving great outcomes. Porter brings local expertise and years of mortgage experience to the VDB Team. He is a trusted advisor knowledgeable in lending practices, laws and strategies. 

Portfolio Director Kelsey Lesefko supports clients in bringing their homes to market and keeping them up to date throughout the listing period. Her experience studying art and architecture while traveling abroad helps her flourish in cultivating interpersonal relationships with VDB clients. Executive Managing Broker Roberta Weresh oversees operations, provides team support and manages transactions. Her sense of detail and design is highly refined, the result of her background in interior design, retail store management and staging business ownership.
