I was extremely disappointed with my appointment with Dr. Fenoy. He spent the vast majority of the time talking about his own issues with insurance, rather than listening to my concerns. He also seemed completely uninterested in helping me find a way to get the treatment I needed. Thankfully, I was able to find another doctor who was able to help me.
