"My philosophy of care is to treat each patient and family with respect and compassion – the way I want to be treated."

About Me


When I was growing up, I loved to babysit my nieces and nephews, and one of my nieces had a rare genetic disorder that required extra care and attention. It took a long time for her to get a diagnosis, and I was curious about the critical thinking of medicine.

My career at Cincinnati Children’s started as a patient care assistant, and I decided to continue my career as a physician assistant (PA) here. As a PA, I provide advanced practice provider (APP) support for six surgical specialties: orthopaedics, pediatric surgery, urology, gynecology, plastic surgery and ENT (ear, nose and throat).

I love the surgical specialties, where I can utilize my first-assist skills and procedural skills when needed. But most importantly, I was drawn to the outcomes that many surgical patients experience. Surgery can improve their conditions, and we get to see the positive impact surgeries can have on their lives.

My philosophy of care is to treat each patient and family with respect and compassion – the way I want to be treated. I try to take extra time to provide the best care and make improvements in patient safety. I’m always excited to see what my patients can teach me through our interactions. I received the Cincinnati Children’s Highest Orthopaedic Patient Experience (HOPE) Award in 2013.

I’m the APP lead for PA Practice. I work closely with the APP lead for PA Education and APP leadership, which provides support for all the physician assistants at Cincinnati Children’s.

When I’m not helping patients, I like to spend time with my kids, doing whatever it is they love or want to do! This usually involves playing in our yard, on the swing set, at the pool or at the park.
