Good GP's in Tullamore?

I've a friend who's looking for her own GP. She was attending Dr. Quinlan's (to see one of the lady doc's) but she's gone and a few weeks ago she was really sick and was only able to see Dr. Aisling since she was the only one with an available appointment for the day and she couldn't wait. She did not like her at all, and she ended up needing to go back down a few days later because she was getting worse. But again, the only doctor she could see was Dr. Aisling. Again, she didn't like her and she got worse and she ended up in the hospital for a week. Now she's worried if she gets really sick again, she'll have to go back to her because she's usually the only one with an appointment available now when you ring on the day. So she would love some recommendations for GP's. I can't help her as I've always gone there, so I said I'd ask here and pass the answers on. Thanks!
