  • Amazing knowledge, clear communication and plan strategy to solve the problem. Very capable of showing in the CT and the colonoscopy images the correlations that show the problem I have and the necessity to solve it fast because of the possibility of an infection in the abdomen ( peritonitis?)

  • I've been seeing Dr. Bleday for 20 years, even though I've moved away three times to where I used to live. I always come to Boston to see him. And he's been absolutely terrific. He's the most knowledgeable and skilled health provider I have. And he's been very personal. He knows exactly who I am. And I've stayed in touch with him over that 20 years. And when I said I wanted to get an appointment, I got it within an hour or two by writing him by email. And he asked for me to send admin materials. I had difficulty with that. He had his assistant reach out and I got that material to him and he used it. He was well aware of exactly where I stood. So he couldn't be better. He's a great doctor and a great human being in all respects.
