David Hammack is a Good listener, patient, professional and pleasant!

04/13/2026

Outstanding! Dr Hammack listens then he tells me what he suggests and then he follows up without me having to call back. For example I needed to see a specialist once I leave the office I have a million things on my mind within a couple days the specialist office is calling to set up an appointment because Dr Hammack did what he said he’d do. Another ex: I had a discomfort in my lower back before for months Dr Hammack stayed on my Insurance company until they approved my MRI after they denied It. I ended up having a cyst in my lower back. I would recommend a friend, a foe, a cat and a dog (I know he’s not a vet) to receive the best care from Dr Hammack who doesn’t rush you and most importantly hears you and follow through every time. I’m very grateful 😊

04/13/2026

I have been with him for years. We've established a relationship. He knows me well. He understands my health issues and he usually gets ahead of them before I can even ask a question. I am happy with him
