    The best. Patient with questions. I’m loaded with issues due to a disease that calcifies my hips, shoulders, back, thoracic spine... it’s a very painful disease. He gets me to see the best specialists and is great with internal medicine. Everyone knows him when I mention his name to specialists, even physical therapists. Great demeanor. Calm and takes time to explain. A specialist recommended him. My lucky day.
