Welcome to SonBob Farm


Located in the rolling hills of scenic East Amwell Township, SonBob Farm offers a friendly atmosphere, fine facilities, and proximity to one of the best trail systems in Hunterdon County.


The Owners

SonBob Farm was started by Bob Petrolino in the early 60’s in Upper Saddle River, NJ! Bob started in the horse industry with Appaloosa’s proudly training and standing an Appaloosa stallion named Haigs Buttons. Bob moved the operation to Ringoes, NJ in 1968 where we are today, and in 1971 began specializing in AQHA bred horses. Bob enjoyed a wonderful and challenging career training horses, standing stallions, hosting clinics & shows at SonBob, and showing client horses all over the US. Bob specializes western training and trained horses for all disciplines. Bob retired from breeding and training for the public around 1995, but remains passionate to share his knowledge should anyone have a question. Bob still enjoys riding his current reining bred AQHA stallion, Almost Whizzin’ by Whizard Jac x Luck’s Doll, bred by Bob and Jane. Jane “borrows” Whiz every once in a while as he is a very talented jumper, and has even evented him!!

Jane came on the SonBob scene in the late 90’s. Jane enjoys eventing and trained SonBob bred horse If I Was Your’s aka “If” an AQHA gelding by Mito Commander to participate in 3 East Coast Eventing Championships. Jane has a degree in Food Science from Clemson University and has worked in the food and animal nutrition industries for many years. Jane has an active interest in breeding quality Hanoverian and Dutch (KWPN) warmblood horses for both dressage and jumping enthusiasts. We are a small breeder that focus’s on quality and we are fortunate to have many happy owners enjoying horses we have bred all over the country. Jane loves her mares and adores riding her favorite sassy mare named Hyacinth by Contango. She enjoys training 2 horses she bred- a Hanoverian gelding named Rotterdam Z (TJ) by Royal Prince and a KWPN mare named Magnolia T by Uno Don Diego. Jane is also passionate about Great Danes, and Great Dane rescue. If you see a Great Dane, Jane is generally nearby!

The Facilities

SonBob’s main barn houses 24 horses with an 8 stall barn behind the main barn. All but 3 of these stalls are 12 x 12 stalls. There are 3 “foaling” stalls that are 12 x 16. All stalls are matted with a tamped quarry screening underlayment as a base. Our turnout areas are generously sized and we practice solid pasture management procedures. All fields are fertilized on a regular basis, and fields are mowed regularly. Our mare field is 15 acres and there 2 fields where geldings are turned out are 9 acres each. All fields are cross fenced with the RAMM Polypropylene fencing for safety. We are on the AVTA trail system.

SonBob has 5 rings for everyone to enjoy. All rings are maintained on a regular basis unless they are frozen in winter. We are firm believers in the first step to a sound happy horse-beyond good care of course-is good, maintained footing. The indoor has a dedicated tractor & drag that lives in the indoor year round for grooming. The outdoor rings have a larger, specialized drag for maintaining the footing. All rings do have lights to accommodate both early birds and late night riders. We have standards & poles in the indoor and jumping rings.

Large Outdoor Ring: 250’ x 400’ with a sand based footing

Large Regulation sized Dressage Ring: Sand based footing

Dedicated Jumping ring: 75’ x 175’ with a quarry screening & sand based footing

Indoor Ring: 80’ x 150’ with a sand based footing

Indoor Round Pen: 40’ x 40’ with a sand based footing

The Environment

Our atmosphere is best described as a fun, laid back facility that isn’t fancy but provides excellent, knowledgeable care. Bob and Jane live on the property with a birds eye view of the barn and pastures. We enjoy a wonderful mix of trail riders, folks who ride in the ring for enjoyment, boarders who enjoy western riding & reining, a group that participates in low level dressage and jumping, and we have several owners board retired horses with us. Having been around for so many years, we are fortunate to have served as a boarding facility to almost every breed and riding discipline!

We do not have a professional trainer that is based out of the barn, but do allow instructors in with appropriate liability insurance. As there is no lesson program at SonBob most of our clients are adults, but we do welcome children should a family wish to board a horse here. We do not have “hours” so we can accommodate the schedule or commute of every owner. We have closed the farm twice for 3 days since 1968…..to pave the driveway!
