Meet Mark Larkin
Your local guide to exceptional real estate across the Southern Wisconsin lakes.

As a lifelong resident of Southeastern Wisconsin with over two decades in Lake Geneva, Mark provides his clients with the unique insight of a true local rather than just a market analyst. Representing Berkshire Hathaway HomeServices Starck Real Estate, he excels in residential, luxury, and commercial sectors, consistently ranking as a premier regional agent through his data-driven strategy and bespoke client care. What sets Mark apart is communication – he picks up the phone, answers questions, and gives his time freely every day of the week, supported by a full-time licensed assistant. Outside of work he's with his family, enjoying the lakes, or pursuing his lifelong passion for competitive swimming.
