What kind of care can I expect from the general surgeons at Greater Regional?

When you make an appointment with our general surgeons, Dr. Heather Osterbrink or Dr. Amy Hynek McFarland, their philosophy of care stands out. 


As a surgeon, it is my goal to provide exceptional care to each of my patients. This starts with educating people about their diagnosis and the treatment plans available. Together we discuss benefits and risks associated with each option. I do my best to assist patients in creating a treatment plan that will meet and hopefully exceed their goals.

My impact on my patients is that I want to be able to provide them with reassurance. Needing surgery can be stressful and scary time in people's lives. Because this isn't a huge hospital, we have the luxury of making patients feel they're not just a number and reassure them that they're going to receive the best care possible.
