Dr. Stein retired as he was having health issues that forced him to. He is around 80 years old. He transferred all his patients over to working with Dr. Chad Oler who you can get in contact with here - Contact | Natural Solutions. I have been working with him for a month now and can say that he could be even better than Dr. Stein. He keeps better records and seems to be more receptive to patient ideas towards what I think is going on and what I think we should do next.
