The Defiance location is the original home of Sorenson Kennels and the foundation of everything we are today. Established in 1954 by legendary trainer Tom Sorenson, this facility has grown into one of the most respected dog training and boarding operations in the country. For over 70 years, generations of families have trusted this property as their go-to destination for world-class training, reliable boarding, and the kind of care that only decades of experience can produce.

Set on 50+ acres of natural countryside in St. Charles County, our Defiance property provides dogs with an unmatched environment to learn, explore, and thrive. From spacious fields and wooded trails to the expansive outdoor training areas, every part of the property was designed to support our programs—from obedience training to long-term boarding. Dogs who train or board here enjoy daily enrichment, structured outdoor time, and the kind of real-world training scenarios you simply can’t replicate in a traditional indoor facility.

As our flagship location, Defiance is also home to our full team of experienced trainers, staff, and support personnel. This is where our methods were developed, refined, and perfected over decades, and where our long-standing commitment to excellence continues every day.

Whether you are looking for obedience training, specialized programs, or premium boarding services, Sorenson Kennels, in Defiance, remains the go-to place for all families in St. Charles and St. Louis counties.
