This guy is a money gauging crook. I had a pretty nasry wart on my hand. After months of painful freezing and hundreds of dollars with no change in treatment he finally admitted there are significantly better options to remove a wart of that size however he does not have the equipment. I asked multiple times b4 if there were other options he continued to say there it nothing better until it was evident he couldnt remove it effectively.
After 1 treatment at arizona derm my wart was gone. And it only cost me a fraction of what i dumped into Dr. R's practice.
Do yourself a favor. Go somewhere else. I've been to several dermatologist over the years, some good so not so good. He is without a doubt the worst Dr i have ever encountered.
