"Dr. Bligh is a wonderful doctor, one of the best in our area! She will be honest, even if it’s difficult to hear. She has an ability to catch and treat what other doctors miss or brush off."
— Patient testimonial for Dr. Sarah Bligh (CNOS website)"First, Dr. Bligh was wonderful and professional... However, the nurse... had a very strong accent and was very rude... she dismissively said she had to 'cover the whole clinic today' and didn't have time."
— Patient review from LocalityBiz"He's my favorite doctor! And I have had many in my life. He's got a great, upbeat personality. He's done two colonoscopies for me and everything went great!"
