Patient
I met Dr Callister in the late 90's while working as a Paramedic. I was floored with his cast knowledge in Cardiology. Fast forward to 2018. He's now my cardiologist. I have pulmonary htn and right side heart failure. He has such a genuine heart for his patients. Since 2018, he almost has me off oxygen and has weaned me from several medications. Certainly in the top 5 in my book!
