Dr. Mares listened to all I had to say and then explained what he assessed the problem to be. He was very assuring in his assessment that I would be fine very soon. I felt confident in his assessment of my condition and of his prognosis.

The care I received was excellent and stream-lined. I went directly from X-ray to my room where my doctor was waiting right outside. He did a thorough exam, explained my X-rays and diagnoses, and then I was immediately seen by the DME provider for my prescribed equipment and also to a trainer who explained my home exercise program. I was very pleased with the car provided.

Dr. Maers always professional, puts me at ease and listens to my concerns and answers all my questions. Half the battle is the relationship with your provider and I can't not say enough about how happy I am with Dr. Maers.
