Dr Kristo is a very good listener and very thoughtful in his responses to your needs and questions. Its rare to find a physician these days who will take the time to do this. i could not be more pleased. i have worked with Dr Kristo for several years now so Im coming from a lot of history and truly know that he is consistently good and very thorough.
