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!!
