"I've been a patient of John Vainder's for many years. He has, during our long association, performed diagnostics, regular maintenance care and monitoring procedures, and during one extremely frightening period, ICU acute care. During my own career, prior to retirement, I was a clinical nurse researcher, over which time I developed the criteria by which I personally 'graded' clinical care for my patients, my family, and myself. I hang my hat on them to this day. My estimation of expert medical care orbits around two specific areas--that of art and that of science. The science aspect I look for is that which surpasses competence--it is about brilliance of mind, thinking out of the box as second nature, in practice, and staying on top of prevailing and new research. Dr. Vainder continues to fulfill all of these criteria in his care of me; it is what brought me into his care. What has since KEPT me in his care and perpetuates my loyalty to him is the art. My experience with Dr. Vainder is pure art which is of the utmost importance to patients in general, and to me specifically. It is his honest, down to earth demeanor, compassion, humor, and respect toward those of us he cares for. It is his depth of understanding of OUR experiences that is the standout attribute of his art : it is my opinion that brilliant scientific care in combination with authenticity and kindness, makes a superior caregiver. I believe the expertise John Vainder brings to his practice in both domains sets a high standard, and is the expressed epitome of this most gifted physician's dedication in his practice of medicine. Best regards, Harriett Wittert"

"I have had a few colonoscopies performed by Dr Vainder over the past number of years. During these procedures, I only had a brief pre-op conversation with Dr Vainder until the sedative kicked in. And of course I hardly ever remember his post-op comments since some of the drug residual affected my memory! I did receive a very thorough written follow up with the results of my procedures. However, I recently needed a procedure to check out some acid reflux issues. During my pre-op office consultation and follow up office visits, I finally got to spend some time with him, unencumbered by drugs etc! I found Dr Vainder to be very personable. He talked to me like one of my friends in trying to determine a solution to my issues. I didnt have to listen to a bunch of "medical school speak" that I probably couldnt understand. After he reviewed op results and with input from me, he proposed a plan for a 60 day period and we would evaluate afterwards. No speeches, no lectures, no big medical terms...just a simple straight forward plan. I really appreciated his honesty and genuine interest in solving my problem. I highly recommend Dr Vainder and have been very pleased with his services."

"I went to Dr Vainder 20 years ago for an issue, and he was great. Then my husband and mom went to him for routine colonoscopies . I recently went to him again for an issue, Because I was dissatisfied with a previous Gastro I saw last year. He saw how nervous i was as soon as he walked in, and sat right next to me looking at some results, and called me down immediately. He was so kind and compassionate and obviously knows his stuff. He gave me some medical advice for my issue, and continued to Calm me down and ask me about my life, why am I so stressed out? He spent so Much time with me, even trying to get me to laugh. Bedside manner is everything to me. I will never mind if I have to see him again! And I am afraid of doctors! He is amazing , and his staff is very nice too. I told him he is not allowed to retire any time soon!"

"Dr. Vainder is an amazing listener...He spends a good deal of face to face time, asking asking about your condition, never sitting at a computer desk. (I don't even think there's a computer in the exam room.) He thoughtfully explains and problem solves with you, and seems genuinely pleased to send you away with a plan that will work. I think he's a wonderful doctor."
