Jen Mills, Farm Manager & Owner of Jen Mills Horsemanship, LLC
(908) 432-7437 - Contact for All Horse Related Activities & Services


"Passion for horses" would be an understatement when it comes to Jen, who has spent over 30 years dedicated to studying the horse. As a youth she filled her days as a working student taking every opportunity to learn from many different horsemen in all the major disciplines. While obtaining a Bachelors Degree in Equine Science from Centenary College in Hackettstown, NJ, she enjoyed successfully showing horses on a national level in Hunt Seat Equitation, on the flat and over fences. She says her career has been a "wild ride" having been employed by an internationally acclaimed trainer as a manager, head groom, and assistant trainer, as well as a navigator and show groom for a Combined Driving Team, and managing many other horse farms in NJ.  "I strive to learn as much as I can from every horse person I meet because there's something to learn from everyone and one can never know it all!"
Now, in the laid back and non-competitive setting of Mortonhouse Farm, she offers her knowledge of horses, teaching safe & proper riding in the ring and on the trails, as well as all aspects of horse care, management, and training "naturally" with anyone who shares her passion. In addition to training and teaching others, Jen continues her education by riding with world renowned horseman, Buck Brannaman, Joe Wolter, and Greg Eliel, as well as Olympic judge and trainer Marilyn Payne.

John Crater, Farm Owner - Hay & Herefords
(908) 612-9174


John made Mortonhouse Farm his home in the mid 90's, the very land his ancestors established 300 years ago. He enjoys raising Hereford Beef Cattle and produces the finest quality Hay for public sale. His love for antique farm machinery is apparent to visitors as they stroll around the farm. When you see him, be sure to ask about the history of his land or anything about farming, as he is a wealth of information.
