Meet the Owner

Andy Stellpflug, owner of Renewal by Andersen of Wyoming, Renewal by Andersen of Montana and now Renewal by Andersen of Rapid City, was born and raised in Wyoming on what is now a four-generation ranch with more than a century of history. The youngest of five children, he grew up in a loving family and was taught all the values that are so important here in Wyoming and beyond: hard work, dedication, honesty, loyalty and an unbreakable bond to family and traditions. He has a love of the outdoors and is an avid hunter and fisherman, and actually grew up riding horses and working cattle — still does to this day, in fact.

He is married to his high school sweetheart, Theresa, and together they have seven beautiful children, the oldest of which are involved in the family business as well. Andy started out in the window business more than 15 years ago and has continued to grow his business skills to acquire a reputation as being honest, fair and hard working. He is dedicated to his customers and his staff, seeing each job through to completion with a focus on customer satisfaction and exemplary service for customers in the great state of South Dakota. You are choosing the best of both worlds, product and service, when you choose Renewal by Andersen of Rapid City.


"We recently replaced all of the windows in our home. I was most impressed with the friendly staff who knew what I wanted before I did. They seemed to be able to find the perfect window for each one we replaced. We are very pleased with the result. From beginning to end they were professional and helpful. I would highly recommend Renewal by Anderson."
