Welcome to Door County, Wisconsin! Please allow me to introduce myself as a Broker Associate and top producer for an exceptional boutique real estate firm in Door County.  I work with The Kellstrom-Ray Agency, which has been in business since 1948.  Our office even has a water view (and great sunsets over the Bay).  I'm an annual multi-million dollar producer, a top producer for the Door County MLS, and a former Senior Associate for Coldwell Banker The Real Estate Group, where I was also the recipient of the coveted Pinnacle Award.  From 2016-2023, I have been the top producer for my brokerage, The Kellstrom-Ray Agency, Inc.  I am also consistently ranked as one of the 5 top ranked agent for the entire Door County Multiple Listing Service for listings and sales.  After my family (which includes our Labradors), my customers and clients come first--we all have a mutual respect for honesty, integrity and hard work. Many of my customers and clients have become like family to me over the past decade, and I have made many close friends.  Contact me to talk about YOUR Door County dream property and lifestyle.

A little bit about me:  active in the northeastern Wisconsin community, a former Legal Assistant (member NALA), I decided to enter real estate sales full time in 2003.   I am a full-time Broker REALTOR, and a consistent top sales producer for the Door County Board of REALTORS. I am also an Accredited Buyer Representative (ABR), an honor proudly designated by REBAC under the National Association of REALTORS, as well as a Certified Residential Specialist (CRS), a designation earned by listing and sales volume, as well as assisting numerous buyers and working with specialized skills for clients and customers.  I have been a member of the Door County Board of REALTORS Honors Society since 2005, have been awarded the Excellence In Professionalism honor and was named Door County REALTOR of the Year in 2008.  During my service with Coldwell Banker The Real Estate Group, I was a consistent top producer and was been named to the Chairman's Circle in 2010, 2011, 2012, 2013, 2014 and 2015.  Providing Pinnacle-Award winning services, I joined the expanded Kellstrom-Ray agency in 2015 to increase my services to my customers and clients. I became a Senior Associate and the Top Producer at Kellstrom-Ray from 2016-2022 with hundreds of millions of dollars in sales production.  I was also named President of the Door County Board of Realtors for 2017, and served as a Director for the Door County Board of Realtors from 2005-2009 and 2018-2023.

When not assisting the customers and clients of our brokerage, I work ceaselessly at a local level representing various non-profit organizations, including a term as the vice president of People, Land and Community Economic Solutions, a task force dedicated to the study of attainable housing. I have served as both a Liberty Grove Supervisor and Planning Commissioner and have served on both Liberty Grove's and the Village of Sister Bay's Economic Development Committees.  I have been a frequent contributor for real estate information at our local school district, Gibraltar Area Schools, which my two daughers attended.

When choosing a Broker or Realtor, choose an EXPERT.  I am your Door County expert.

Door County Properties--known as the "Cape Cod of the Midwest", I actually had a friend visit Cape Cod and come back to Door County having been disappointed by the real "Cape Cod".  He said Door County is much more pristine and truly lovely!  We are a county with more lighthouses than any other in the United States, and nearly 300 miles of shore, with Green Bay, Lake Michigan, and several inland lakes.  I special in waterfront  and view properties throughout the Door Peninsula, and have had some record listings and sales for the State of Wisconsin, but I work in all price points, throughout the Door Peninsula, to better assist my customers and clients.  From residential condominums to luxury waterfront properties to starter homes, I provide knowledgable, ethical and thorough service.  Door County Properties range from quaint cabins in the woods, to luxury townhomes on the water, to equestrian estates, to inland farms.  We are sheltered by both Lake Michigan and the Bay of Green Bay, and are a waterfront community at every turn.  Lake Michigan is the quiet side; buffered by sunsets over the Bay of Green Bay.  I am your embassador to Door County, and I take my responsibilities seriously. Vacations turn into traditions here.  What is YOUR Door County dream?
