Dr. Mel stayed open for me beyond normal hours for an urgent visit. I called just before closing and he stayed for me. I appreciated this so much as he is a very kind Dr. and gave me great comfort. Showing me the EKG as it was happening. He has taken care of 3 of my Grandchildren as they have asthma issues. Yes it was expensive, but well worth it and I had zero issues with the time frame for billing. The staff was so nice over the phone, asking if I was feeling better and even the off-site billing agent wrote a note and said "Hope you are feeling better".
