Yes, I have been a patient of Dr. Palacios for many years and he has given me outstanding medical advice, any other term that you want to use. I've referred him many times to other people. My only regret is that Dr. Palacios, like myself, is getting along in years and I don't know how much longer he would choose to practice. And I don't know what I'm going to do without him. That's the end.
