What Sets Greenleaf Apart From the Pack?
Our Luxury Facilities
Our two properties are both outfitted with private, glass-walled suites for each dog so we can give them their space while keeping a watchful eye. Our Millstone facility is located on an idyllic, 56 acre blueberry farm with extensive space for dogs to roam and explore, while our Oakhurst location is in a suburban area ideal for convenient pick-up and drop-off. From tension-reducing floors to protect their joints, to climate-controlled indoor and outdoor play yards, we’ve considered every detail of our facilities with your dog’s comfort and safety in mind.

Our Proprietary Training Method
Pioneered by co-founder Shelly Leibowitz, and developed over the course of 40+ years, our method for training dogs is unlike any other. We use short bursts of training based on a dog’s maximum attention span– interspersed with periods or play, rest, and enrichment so your dog is having fun the entire time. We teach dogs good behavior solely through positive reinforcement and attentive kindness, and work with your family to keep reinforcing what your dog has learned once they’re back in your home. Through this highly effective method, our trainers have successfully trained even the most “untrainable” dogs at Greenleaf.

Our Knowledgeable and Attentive Staff
When your dog stays at Greenleaf, they’ll have round-the-clock attention from our staff to meet their every need. We take pride in providing personalized care for every dog that steps into our resort. Every dog’s idea of a great vacation varies based on their temperament, age, and medical needs, and at Greenleaf we pay close attention to each and every one.
