Please advise me how to attract customers for my mom's dental clinic?

Hi friends, my mom is a dentist and she's extremely hardworking and caring, and our dental clinic is of high quality and very near the center of the city. The problem is that many others had been opened quite a long time before ours, so though they're not so good they have a large customer base. My mom's sad and I really wanna help her. Already read some marketing books, thinking of re-designing the clinic, creating a website, and distributing leaflets. Any comments and suggestions will be deeply appreciated!

See a small percentage of kids with no dental insurance at an affordable rate for the Parents. That in itself won't bring much profit, but the goodwill shown to the community will bring many rewards in the future.
