Dr mellish takes the time to listen and answers questions in terms that you understand. You don’t need a medical degree to understand his diagnoses and results of any tests you’ve had done. And he also has a sense of humor. He’Show mores tops in my book!!

Dr. Mellish is the best doctor I have ever had. He listens to my concerns and addresses them accordingly. My husband and I both use Dr. Mellish and followed him from Elliot. And if he ever leaves SNHIM, we will follow him again.

Dr. Mellish provides good advice and his office is run efficiently - very little waiting, easy referrals.

Todd D. • January 30, 2025

Dr. Mellish was his usual, attentive, concerned, doctor self today. A model doctor he is! He checked me out thoroughly. Made the arrangements for blood tests and determined that I am doing great after checking all my vital statistics. He was very pleased with my current appearance. He arranged for my next visit in four or five months and gave me the paper work for blood tests I need to have done in 4-5 months. He keeps very close tabs on me given the heart attack Ihat I had in December of 2023. Given my age, 86, he keeps very close tract of a number of other issues concerning my overall health as well. He's definitely a 10! He is equally attentive concerning my wife's health as well.

Edward D. • January 30, 2025

Dr. Mellish is the best. He is extremely professional and cares about your well being and health. I have been a patient of his for over 20 years. Strongly recommend him.
