Peter Mahler
Mahler Sotheby’s International Realty is a boutique real estate brokerage specializing in representing the buyers and sellers of extraordinary homes throughout Wisconsin. Our consultative approach and clear focus on gracious service and exceptional results has made us unique from the North Shore to the western suburbs, Lake Country and beyond. Our association with Sotheby’s International Realty Affiliates LLC was born out of a desire to open up a new world of marketing channels and exposure—yet never outgrow our key mission to meet the uniquely individual concerns of each of our valued clients.
Our team members represent a diverse and inspiring variety of educational backgrounds and professional pedigrees—including commercial and residential cleaning, private staffing, construction, architecture, interior design, graphic arts, retail management, marketing, sales and finance.
With this collective resume and the broad real estate experience of our Managing Partners, our brokerage stands far beyond industry standards—deploying a combination of know-how, a preeminent global brand, leading edge technology and old school customer service principles.
A leader in providing exceptional real estate services, Mahler Sotheby's International Realty has established a corporate philosophy of giving back to the communities where we live and work. Our giving and the organizations we support come from a desire to expand our legacy of philanthropy in tandem with our dedicated agents and staff.
