I was worried about new spots on my skin and received a quick appointment. Ashley found the spots on nose were just broken capillaries- phew, not cancer! The spots on chest was pre cancerous and she froze that. So happy my worries were promptly addressed!

Ashley is great. She doesn’t rush so she’s sure she’s not missing anything and she’s very thorough which, to me, means everything. Some doctors make you feel like they’re trying to make a quota but she’s not like that. She’s always able to answer any questions and she is friendly and kind. This practice is lucky to have her.
