I have been working in the field of reproductive medicine since 2004 and joined Kettering Reproductive Medicine in the fall of 2011. I love reproductive medicine because it allows me to study complex physiology while expanding my advanced practice nursing skills every day. Nothing is more rewarding than helping couples build their families, and the best moments are when patients come back to introduce us to their babies - that's what keeps me hopeful and working towards success for every couple I meet.
