Mark is fantastic! Our dog, Loki, was fear aggressive and very timid. He wouldn’t mind, wouldn’t obey basic commands, barked at everything and would lunge at people. Mark took him for 30 days and brought a totally different dog back to us!! And when he brought him home, he spent over an hour teaching us the proper way to handle Loki. I would HIGHLY recommend Mark if you have issues with your dog!! He is patient, gentle yet firm and shows a true love and understanding of animals. He is just an awesome trainer!! Mark went the extra mile and gave Loki a “birthday party” because he turned 1 year old while he was with Mark for training. That was above and beyond and will never be forgotten. Loki loves Mark and that says a lot, because Loki doesn’t like most people!! Thank you, Mark, for doing such an awesome job with our boy!!
