Anthony is the absolute best! He is such a joy to work with, and my dog is completely obsessed with him. She literally cries at the door when he leaves! He is incredibly knowledgeable when it comes to dog training and understanding their behaviors, but what really sets him apart is how approachable, patient, and helpful he is.He is always available to answer questions and offer guidance, which means so much. After having a difficult experience with a previous dog, I can’t tell you how reassuring it is to work with someone who truly understands dogs and knows how to help and offers the best advice that actually works. We are so grateful for Anthony and couldn’t recommend him more!

Thank you so much Mary Kate! I enjoyed working with you and Tess. She was so much fun to work with and has grown so much! I can't wait to see her continue to grow and develop into an even better family dog then she already is.

As a professional trainer, I was interested in expanding my skillset and getting hands-on experience in a few specific areas. I had already completed several well known online courses focused on the theory behind different approaches, but I wanted the opportunity to put that knowledge into practice with my own dog. I reached out to Anthony, and he was extremely open to working with us. We focused on improving my dog’s off-leash skills, including recall around distractions like dogs and prey, as well as building more ease around passing other dogs without planting to greet them. Some of the concepts were new to me and pushed me outside my comfort zone, but Anthony was super supportive and nonjudgmental throughout the process. He’s incredibly knowledgeable and patient in his coaching, while also knowing when to give you that little push to keep growing as a trainer! I really appreciated the opportunity to learn from him and would highly recommend him to anyone looking to expand their skills!

Thank you so much for the kind words Kate! You and Bandit have done such great work and I am honored to have had the opportunity to work with the two of you. I look forward to seeing you both continue to grow. AND I look forward to seeing more of Bandits off leash adventures!

Anthony is a gem! He couldn't have been more patient with us and our puppy. With his help we were able to curb some bad behavior from our pup and build great habits as dog parents. I highly recommend him for anyone considering his services. You won't be disappointed.

Thanks so much Jordan! I appreciate it. Glad things have worked out well. I looked forward to hearing how things continue to go as she continue growing and developing. Reach out if you need anything.

When we first started working with Anthony, our Giant Schnauzer rescue was just a year old and struggling with severe anxiety around people because of his experiences before we adopted him. Fast forward five years later, and the transformation is nothing short of incredible. People who knew him then often comment that he's a completely different dog today.
What sets Anthony apart is that the focus was never just on changing our dog's behavior. It was on teaching us how to better understand him and create an environment where he felt safe, comfortable, and confident enough to build positive relationships with new people. That perspective completely changed the way we approached his care and made all the difference.
Anthony also helped us prepare for one of the biggest transitions in our lives: bringing home our daughter. The guidance we received gave us so much confidence and helped ensure a smooth, positive introduction for everyone.
Even years later, whenever we have a question or concern, Anthony is always quick to respond with thoughtful advice, practical strategies, and genuine care. It never feels like a transaction. It feels like having a trusted partner who truly wants the best for our family and our dog.
The greatest lesson we learned is that successful dog training is often less about training the dog and more about training the owners. That insight has been invaluable and has strengthened the bond we have with our dog in ways we never imagined.
We are beyond grateful for the patience, expertise, and ongoing support we've received. Watching our once-fearful dog grow into the happy, loving, and confident dog he is today has been one of the greatest gifts. We cannot recommend De Marinis training highly enough.

Samantha and Marianna, Thank you so much for this review. It is so great to see five years later that things have only continued to improve, especially as your family has grown. You are so right that training half the time is more about teaching the dog owner rather than the dog!
Thank you so much for the kind words and so happy to hear from you both many years later. Keep me posted and I will continue to look out for the instagram updates that I see from time to time. Wishing you and the family a wonderful summer!

We had a great experience working with Anthony. From the very beginning, he was patient, knowledgeable, and genuinely cared about helping us and our dog, Bruno. He took the time to explain everything clearly and provided practical techniques that were easy to implement at home.
We’ve seen a noticeable improvement in Bruno’s behavior and confidence, and we feel much more equipped as owners because of his guidance. Anthony’s positive approach and dedication made the entire process enjoyable and effective. We highly recommend Anthony to anyone looking for a skilled and compassionate dog trainer.

Anthony has been working with our 10 month old golden doodle since Chester was eight weeks old. I don’t know what I would have done without Anthony. He taught us so much and we’ve been dog owners our whole lives, but he taught us things we never even thought of. My spirited dog is very well behaved all because of Anthony but he’s more than a trainer. He’s become a great family friend.

Carrie, Thank you so much for the review and the kind words. You guys have done such a great job with Chester! And I can't wait to continue helping you and working on some of your continued goals. Keep up the great work!

My wife and I have been training with Anthony since Aug 2025. I find Anthony an exceptional dog behaviorist. He has been able to train my wife and I on how to address our 3 year old mutt that is reactive to other dogs while on leash. We have worked individually and with groups of other similarly challenged dog parents. Anthony is able to customize the training needs to specific behavioral issues, which is very valuable when dealing with different types of dogs. I’ve seen his personal well behaved dogs, and other dogs he has worked with. Anthony is worth the time and money to help new and older dogs and their parents.

Highly recommend training with Anthony if you are looking for a knowledgeable dog trainer! When we first started training with Anthony, our puppy struggled with leash manners so long walks were a struggle. After one session with Anthony, he helped us to understand our dog’s needs and now walks are a breeze! Anthony truly cares and takes his time to get to know each dog he works with. Anthony has taken the time to get to know what our dog needs and is always open to trying different ways to help reach our goal. He’s helped us work through separation anxiety, basic obedience, boosting our pups confidence and has taught us how to strengthen our relationship with our dog. We are constantly learning something new each time we train with Anthony. We are so thankful for him and highly recommend training with him if you need professional guidance with your pup like we did!

Natalya, thank you so much for the review. I am so happy Rocco has improved and made so much progress. He is such a cool dog! Keep it up as you both have made so much progress. Cannot wait to see him continue to do great things!

Before working with Anthony, walking with our dog Kent was extremely stressful. He struggled with leash pulling, and leash reactivity which made even short walks feel overwhelming. We love going to breweries with him, but his reactivity when other dogs came in made it unpredictable.
From the very first private dog training session with Anthony we saw improvement — not overnight, but in a way that actually made sense. Anthony took the time to explain why Kent was reacting the way he was, pointing out his body language, triggers and stress signals. The lessons were clear and realistic and were super easy to apply in our walks and outings.
We worked through different leash and collar combinations to find what works best for Kent. This has made him more confident, focused and less reactive.
After we started training, walks are calmer, more controlled, and genuinely enjoyable. We were able to be transitioned to a group class where we are able to see so many more improvements. We really appreciate the training not being a one size fit all approach. The transformation has been incredible. Anthony is an amazing person to work with!
If you’re struggling with leash pulling or reactivity or other behavior issues and feel stuck, Anthony is absolutely worth it. This training didn’t just change Kent’s walks — it changed our relationship with him.
Response from the owner · 10 months ago
Stephanie! Thank you so much for this review and your kind words. It is insane to see how much progress you and Kent have both made! He was so vocal before lol! You have put in the work and it shows. You have done a really nice job at understanding your dog and knowing how to handle him in certain situations. I can't wait to see him rocking it at a Brewery and I look forward to seeing him continue to thrive in group class. Keep it up!
