“Mary, you are literally a miracle worker. I just wanted to say thank you, as [the cat] is like a whole new cat while they are gone. Loving, playful, sweet, wanting lots of pats and rubs and attention. She’s been grooming (which I’ve actually never seen her do before), blinking, her tail is always up and she seems happy. She’s getting lots of play time and I’m going to buy new toys for her today (especially a cat dancer, as she loves to follow things now). She’s been following the stick up onto chairs, the table, all around, and doesn’t even take the treat half the time! She just loves the play. 😊 THANK YOU!!!!!!”

“My husband and I are so happy to have been referred to Mary. Our pup, Gus, was 3 months old when we first started working with her and so much of what she taught us in the beginning had us smacking our heads and saying “duh!”, but as first-time dog owners we just didn’t even realize so much of the stuff we were supposed to be doing with him! Whenever Mary would walk in our door Gus would get so excited, which is exactly the response you want your dog to have to a trainer. Gus is such a better puppy and we owe it all to Mary. Couldn’t recommend her enough.”

—Leslie Buller and Jeff Hoffman and Gus

“When to call in an expert?? I’ve had cats most of my life. Growing up I had a cat “Jellybean” who had a few litters of kittens. But now having a cat who is 18, two kids and deciding to add two kittens to the mix made me think – this is a new scenario and I wanted to set all of us up for success. Nirvana Tails LLC was my first call. Mary has such a gift for training cats, dogs, kittens, puppies and PEOPLE. My kids listened to every word and ran with it. Now I hear, “Mary said …” all the time! We have a ways to go, but we all feel prepared!”

“Mary approaches her consults in a very professional manner and works to a high standard. She is well prepared and very knowledgeable but not rigid in her views and always open to considering other viewpoints or new scientific findings. She uses her knowledge and skills to custom tailor her methods/consults to the need of the owner, and does that in a very gentle way, which is a pleasure to observe. I have already recommended her to friends in the NYC area and will certainly continue to do so.”

–Irene-A. Zimmer​​, Dr.med.vet., MRCV

“Mary exemplifies everything a professional dog trainer should be. She has a wonderful understanding of dog body language, behavior and training, and a strong commitment to continuing education. Mary also has the gift of being able to explain this information in a way that people can understand. When I get requests from people looking for canine behavior help in NYC, Mary is a trainer I strongly recommend.”

“I just wanted to follow up and say that you’re a great advice and training work! [sic] Naomi slept on my bed last night for the first time! She is jumping all over the place upstairs and seems to be really happy. She still a little skittish and scared but we did the hard part and she will calm down now–we did it! Thank you so much!!!!”

–Stephanie Wade and Naomi, New York NY

“My husband and I were so pleased with the dog training provided by Mary for our Papillon, Sandrine. Mary gave us so many suggestions and techniques to help us deal with our dog’s fear of other dogs and skittishness around people. She also helped us train our puppy to do basic commands and make the walks in our busy neighborhood less stressful and more enjoyable for all of us! One of the most useful tools Mary gave us was fantastic follow-up emails and handouts after each session to review what was taught and explain in greater detail each command or strategy and ways to expand on it. We keep these in a folder and refer to them often. Overall, I highly recommend Mary as a dog trainer who uses only positive training methods and gets the desired results.”

–Lisa Seacrist and Sandrine, Forest Hills, NY

“Jackie and I wanted to say HUGE THANK YOU. This training has been a life saver. If we didn’t start the good behavior training early I don’t know if we would have survived this first week [with a new baby]. I’m so so so relieved and Morgan seems relieved too to be honest.

​You genuinely may have saved and kept a family not only together but happily under one roof in the most stressful times. We can actually enjoy these precious moment without worrying excessively about Morgan.”
