    Dr. Kohlbrenner was very professional, courteous, knowledgeable and well experienced. He clearly answered all my questions and helped me review specific risks/benefits of the PAE procedure specifically applicable to my case based on CT scan and other data.

    This was a textbook excellent telehealth visit. This was as good as any In-office visit I've ever had - all points, questions, risks and options were thoroughly covered. I never felt rushed and felt respected throughout.
