About Diana

For Diana, real estate isn’t just a job—it’s a way to share the Northwoods life she loves. After moving to the area 24 years ago to escape the city hustle, she turned her passion for the region into an award-winning career and has dedicated herself to helping others find their own slice of paradise. Diana’s commitment to excellence is proven by her track record: a Multi-Million Dollar Producer for 10 consecutive years and a consistent top-tier performer among Century 21 agents in Wisconsin. More importantly, she is an 8-time recipient of the Quality Service Pinnacle Award, a testament to the high level of service and impeccable attention to detail that keeps her clients coming back. A lover of nature and a keen photographer, she brings a unique creative perspective to property listings. Diana lives in Iron County with her husband, Frank, and spends her free time tending her perennial gardens, photographing local landscapes, chasing waterfalls, and enjoying the shores of Lake Superior. Whether you are buying or selling in Iron or Vilas County, Diana is ready to help you make your Northwoods dream a reality.

Choosing Diana to be our broker was by far the best decision we made in selling our mothers house. She was extremely knowledgeable and helpful with every aspect of preparing and selling the house and exceeded our expectations at every turn. We highly recommend Diana as a broker to anyone looking to move a property in the Mercer area. On a scale of 1-10 she is a 100

Diana does an excellent job marketing and pricing Raw Land. The parcel I sold had been in my family for over 60 years and trusting Diana with the sale was important to me. Thank You for all your excellent photos and your hard work getting the deal closed.
