    *Dr. Shannon O'Connor is brilliant and compassionate, I could not wish for a better doctor! I love her!
    *Dr. O'Connor is an excellent doctor. She is very knowledgeable, professional, and very easy to talk to.
    I asked specially to see *Dr. Shannon O'Connor - waited 20 mins. in patient room, and the doc that showed, acted stressed and note: I asked receptionist BEFORE coming in to see *Dr. O'Connor! Doctor wanted to quickly get through my visit. I came because I have had IBD since 2010, and I was showing symptoms of "bleeding." I was very concerned w/my situation and my "flare ups" and wanted another "colonoscopy" to check my conditions. INSTEAD she sent me a "brush kit, fecal immunochemical test???" I am seeing another doctor AT "O_____ Care," who is open to researching my concerns & conditions.
    We are VERY lucky to have chosen *Dr. O'Connor as our primary care physician. Her attention to our needs proved valuable because in the subsequent visits to her referred doctors, they have discovered important health issues to deal with now.
    Met w/*Dr. O'Connor only once, but was thoroughly satisfied. Got referral I needed ASAP. Per visit w/PA also email. Got _____ I needed.
