Care options beyond insurance

Five reviews come from anxious patients who felt at ease here, and nine mention having things explained before they were done. Gentle treatment gets six mentions. The office closes by 4:30 pm on weekdays, 2 pm on Friday, with no weekend hours, so it is harder to fit around a 9-to-5.
