Ratings & Reviews
How was your appointment with Dr. Fischer?
Dr. Fischer is an excellent doctor. He really cares about his patients. Will take the time to answer your questions, explain options & procedures. However, because he does care about his patients, he very often runs over. I've personally waited almost 2 hours to see him. However, the staff does not alert you to his lateness when you check in to ask if you'd like to reschedule. The only time I've gotten in too see him on time, is when I get the 1st morning appointment of the day.
