Dr. Klancar hello it's Anita Toal and thanks to you I am a 10 year survivor today. I can't tell you how I thought about you today. You treated me and my husband Brian Taylor with so much care. I lost him in 2011 but know he is in a better place. I just wanted to let you know I am so grateful for you and all you did for us. Living in California with family Amen
