Yes, Dr Koester was awesome!! This was my husband & my 1st visit with Dr Koester, after my husband's cardiologist for 20+ yrs retired. We were not expecting the same level of care that we had received. Boy, did Dr Koester prove us wrong!! Dr Koester took the time with each of us to assure we were comfortable, and understood what he was saying. We look forward to the same lasting professional & friendly relationship with Dr Koester as we had!! Thank you!!

Dr Koester was very cordial and thorough in his demeanor in communicating with me about my Afib condition. His respect and care for me as a 90-year old patient was not only exceptional but reflects his excellent breeding. He took my arm and personally escorted me back to the waiting room & to my friend.

Dr. Koester is kind ,compassionate,and is a very good listener. I trust him because he aways comes up with a reasonable plan,even though I can be high maintenance at times. I hope he never loses that compassion that is so lacking in some doctors nowadays.
