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 ,

Karen has been my provider for years, she LOVES what she does. She's passionate about her patients, and utilizes her practice to educate new nurse practitioners in training. She calls me out when I need it, but gives me grace and compassion when I struggle with my disease process. I would recommend Karen all day, but realize you will always get the hard truth with compassion and care
