Mark is amazing to work with. He is so good at what he does, he makes his classes fun and easy to understand, he ensures both owners and dogs fully understand what is taught in each lesson and is willing to communicate during the week if you have any questions. We have completed the basic course offered at LCOT and I can't say enough good things about it, especially after doing other courses with other trainers and seeing little to no progress in our pup, it wasn't like anything we had done before, Mark actually took the time to work with the dog and us instead of reading material from a book and expecting you to teach it to your dog with no demonstration. The positive reinforcement technique Mark uses is so effective, my pup, Brant responded very quickly to everything that was taught and we are continuing to grow on his skills in the intermediate course. The positive reinforcement technique and many other positive reviews Mark has recieved are the two reasons we decided to contact him and work with him. Most trainers use shock/e-collars, prong collars or choker chains, to me, that isnt't training, that's forcing a dog to do what you say so they don't feel pain, because of positively training Brant, he WANTS to listen to us. I would 200% recommend Mark.
