In short, Marc is a miracle worker


"All of my years of schooling in animal behavior didn’t begin to compare with Marc’s experience with challenging dogs.  He knew immediately the best way to deal with Heidi’s issues and we are all much, much happier now.  I can’t thank him or recommend him enough.  If you have problems with your dog, take him/her to Marc!"
