    Rest In Peace Bill. I hope they have bikes and 'copters and tools for you wherever you are. I didn't know you for very long and truly wish I had known you much sooner, I'm sure I could have learned a lot from you. In the little time I did know you one of the greatest impressions you made were of your mechanical skills and discipline in carrying them out. I will lift a Coors Light or two in your memory. My sincere condolences to Betty, Cathy, Mike and family. From Roger the Brit

what our families say

Tiffany Foster went out of her way to fulfill all my requests, talked me through problems I was facing, and tried to make me feel as comfortable as possible when I was a wreck, totally crushed, and I thank her with all of my heart for that.

The professional manner of the staff made a difficult time a little easier.

Lynda R. | July 2020

Services provided for both parents were perfect, on time, and no issues. Brenda is awesome and strong!

Michael M. | July 2020

Skyler was absolutely amazing. She was so caring and helpful through this whole process. She even went above and beyond to meet with us in DeForest and even to make a stop at our home to drop off or pick up anything needed. While it was a small gesture, it was so helpful and greatly appreciated.
