(Select your rating)
Dr. Kastoon is an amazing doctor. He is responsive and listens to his patients. He treats his patients not as a set of numbers but takes care to respond to their many concerns. He is also careful and his diagnosis instincts are strong. I have been very impressed by his compassion, care and medical instincts.
