I have been seeing Dr. Kassar for over 10 years. I used to see him when he was 15 minutes from my house. But his office moved one way and I moved the other way putting us over about an hour apart. I see him twice a year for Type IShow moreI diabetes and hypothyroidism, and the drive to see him for the continuity of his care is WORTH it to me!!! Love this doctor!!!
