Patient verified via Press Ganey

Dr Mamelak discussed the results of the MRI of my pituitary in detail. We discussed potential solutions and decided the best was to watch and have another follow up in one year. I am pleased with his thoroughness and recommendations. He is kind and thoughtful and provided information in a way that I understood. I am comfortable with his recommendations and much relieved after my appointment.
