Dr. Kastoon is an amazing doctor. He is responsive and listens to his patients. He treats his patients not as a set of numbers but takes care to respond to their many concerns. He is also careful and his diagnosis instincts are strong. I have been very impressed by his compassion, care and medical instincts.

Dr Kastoon is a great doctor listens to your problems and wants to do everything to fix them. The office help on the other hand is awful they will put you on hold and forget your there it is so annoying. We as patients have emergencies at times and need to get a hold of the doctor or at least an answer! I really hope they will fix this problem because I will continue to see dr. Kastoon in spite of this problem because he cares I just wish they did.

I met Dr. Kastoon for the first time last year. I was referred to him by GP for my Diabetes. Immediately I felt a warm disposition about him and didn't hesitate to share my story. Dr. Kastoon clearly earns high marks in my book, for treating his patients as humans! Thank you doctor; I hope to visit again soon!

We have been going to Dr. Kastoon for many years now and he is tremendous. The only issue we have is that the Admin staff is super sloooooww, but he is worth the wait, I assume the time is slow because he spends a good amount of time with each of his patients. Good luck getting in touch too since the phone line is almost never answered and appointments are hard to get. Again not his fault but I would recommend figuring out a way to run the Admin side better.

Doctor Kastoon is the best Diabetic Doctor I've ever known. He takes his time with you and doesn't just treat you like another number. He's caring, thoughtful and has compassion for you. I'm very very hard person in controlling my sugar levels, but he won't give up on you. I highly recommend Doctor Kastoon!!

I really like Dr Kastoon, he's been my doctor for a year and a half now. He listens carefully to you, working with your concerns, answers your questions without an attitude that many doctors have when you ask them questions, and he remembers you even after months between appointments! He's a great, caring and knowledgeable doctor, willing to go the extra mile to help you, and I recommend him to all! :)
