Training classes are great. However the root of the problem is the greeter. Wether it is A family member or a guest, they need to be informed of the proper way to greet him. There is no need to be insensitive about it, just inform everyone that this is in the best interest and for the mental health of the animal. Over time you will find much more enjoyment from the animal. I have not had this problem with family members but have had friends who felt that getting the dog all wound up was the proper way of showing affection. This always set my training back quite a bit. Oh and don't forget the classes, take the girls with you. There is always something new to learn. Good luck.
