As soon as I was recommended to see Dr. Marella by a hospital many months ago, I immediately knew I wanted him to by my permanent doctor. He is very attentive to every question I have and addresses all of my concerns. He also explains and teaches me the differences between everything that I am going through and always sends me to the best specialists if there is something he is not too sure about. I would highly recommend Dr. Marella to anyone looking for a trustworthy, caring, respectful and kind doctor.

I went to Dr. Marella in search of a new Primary Care Physician 4 weeks after Open Heart Surgery. Dr. Marella was highly recommended by my Cardiologist.
What a neat, neat guy this is. So smart, very careful, completely thorough, and he expertly laid out a plan to help me with my specific issues post CABG as well as plans for overall good health.
His manner, conversation and interest were awesome, and he addressed/exolained-to both me and my spouse equally... which was nice.
I'm grateful to be introduced into his care.
