Laser Specialist Dermatologist Recommendations?

Does anyone know a dermatologist that specializes in lasers? I am currently looking for a dermatologist who can help me with a few little veins under my nose and on my legs, and also some random age spots sprinkled on my body. I have had one doctor burn me a year ago under my nose while zapping one of the little veins, leaving a little hypopigmented scar. Because of this, I'm very cautious in finding the most qualified, knowledgable person.
