Allison Kirsch: Broker - Owner - Realtor

Welcome to O'Sullivan Real Estate! My name is Allison Kirsch and I have specialized in the listing and the sale of waterfront and golf course properties since 2001.

I began my career as a real estate agent in 2001, followed by becoming a licensed real estate broker in 2007 and purchasing O'Sullivan Real Estate in that same year. My passion and commitment to my clients when selling their property is achieved by customizing and crafting a marketing plan that is best suited for that particular home. I also truly enjoy representing buyers in their search and purchase of that special home, where memories will be created with both family and friends.

I am actively involved in the St. Joseph County Association of Realtors and have served as a director on the association board. I have also served on the Klinger Lake Association Board since 2011. My involvement with these associations allows me to stay connected with the latest trends on both the waterfront and with golf course properties. Mark and I proudly support the Habitat for Humanity in St. Joseph County.

My family and I relocated to the Sturgis Michigan area where my husband grew up, in the summer of 2001. Our home overlooks the Klinger Lake Country Club golf course, with the front nine in our backyard and the back nine in our front yard. We are also just steps from the pristine 840-acre spring fed glacier lake, Klinger Lake.

The Kirsch Family has been a part of the rich history of the Klinger Lake and Klinger Lake Country Club for five generations. My husband Mark and I have three daughters that are sprinkled around the country chasing their dreams. Our daughters love coming back to lake any chance they get to be on the lake and visit with family and friends.
