      From the very first appointment, he was professional, knowledgeable, and genuinely caring. He took the time to thoroughly explain everything, answered all of my questions without rushing, and made sure I felt comfortable with the treatment plan.His bedside manner is exceptional, and his skill and expertise truly stand out. The level of care I received went above and beyond what I expected. There really needs to be a "phenomenal" box to check on the survey because "very good" simply doesn't do him justice.
