Mel Riegsecker

Founding Partner

Mel Riegsecker, the eldest son of an Amish family, was born in LaGrange County, Indiana, and grew up on the family farm his parents purchased 2 1/2 miles southeast of Middlebury. Like many Amish families, in addition to farming, Mel’s father had a second occupation; he made and repaired harnesses for the local community. With no desire to go into the family business, Mel went to work in the RV industry.


Drawing on his background, Mel developed a hobby of making miniature horse-drawn vehicles complete with horses and harnesses. Mel’s creations became highly sought after collectibles. In 1980, his hobby became a business. Mel left his job in the RV industry to create the horse-drawn models on a full time basis. June, his wife, was involved in the business from the very beginning.  In addition to being a full time mother with two preschool-age children, she also made the clothing for the models on her home sewing machine.


After starting in the garage, a small building was built for the “horse operation”. In 1984, an old factory building was purchased in Shipshewana and given a face-lift. In May of 1984, the Riegseckers moved the horse operation into what is known today as the “The Shipshewana Craft Barn”.  June opened a small gift shop in the front of the store where quilts and other handmade items were offered for sale.


From this humble little store, the business grew to encompass the 750-seat Blue Gate Restaurant and Bakery, 350-seat Blue Gate Theatre, 154-room Blue Gate Garden Inn, 3 retail stores, a custom cabinet company, a horse and carriage business, and a catering division.


Mel and June have been married for 43 years and have two children: Kathy (married to Phil) and Ryan Riegsecker (married to Jodi). They have 7 grandchildren. Both children and their spouses are involved in the business.
