Cornerstone health’s services are a refreshing experience. Unfortunately, this is not found many offices. Karen, (sunny) Ridenour cares about her patients, reflected in her competence, caring staff. Calls to their office are anShow moreswered or returned promptly. With all of my personal health issues Sunny manages to keep me going. She also realizes the importance of my psychological state when getting worn out with my many problems. I can’t give enough accolades to Cornerstone Health ,
