Dr. Kumar did my pacer replacement surgery. It was an unorthodox treatment due to an injury on my left side, causing them to have to install it on my right, a significantly harder procedure, i was on the table for 3+ hours, and he did an amazing job. I know it was very difficult for him and he preformed the work flawlessly. Yes, the office is VERY busy, but the turn around is generally less then an hour in and out, depending on your personal health and mobility. the staff is extremely busy and attentive, so while it may seem a bit... flustered and calling may be a bit of a challenge, they are a small staff and they do very good attentive work. Everyone is kind and they never rush you, the congestion at the office is the sign of a quality physician and specialist, so yeah... not the most pleasant office, but you're there for the care not the ambiance, the services they provide deserve a better rating. they could use a little more staff or a new, larger office, sure. none of that matters when you're on the table or in the hospital though, so they deserve five full stars for their hard work.
