  • I highly recommend the weight loss program through Dr. Laurri's office. Working with Katherine Pierce, NP, I have finally found a program that works for me. Food choices are perfect. So far I have lost 30 pounds in 3 months, and that is without exercising, as I am unable to. Definitely a successful and easy program!

  • Dieting can be a daunting experience... but Kathy Pierce provided the support and encouragement along with an informed explanation and suggestions to assist in my efforts. Since my first appointment, I have lost 19 pounds in 5 months. I am taking it slow and steady, but succeeding!
  • I have tried to lose weight all my adult life and have tried every diet you can think of. None of them worked as well as the program with Kathy Pierce. I have lost 77 pounds in 9 months and couldn't be happier with my life right now. Kathy is so awesome, always right with you cheering you on through your weight loss.
