I met Jeff at a dog training meet up group that he held for free for people with dog problems, or those interested in dog training.  Jeff was so generous, worked with all the many dogs.  I was amazed b/c after 5 minutes of Jeff working with Ozzie I no longer recognized my dog.  He was sitting and staying on command.  I was sold, and since Jeff has been a god sent once a week  for me and my dogs, and my dogs and I, are thrilled!
