5 Stars  I was very pleased with Dr Biltz and his staff. They quickly put you at ease and he was very polite. He was not presumptuous and asked permission before he examined any part of my body. It’s very daunting to have someone scanning your body with their eyes but he made sure I felt comfortable which I greatly appreciated. –
