Meet William

I have been a family nurse practitioner since 2017 and been with Mercy since 2021. I see a wide range of health concerns. I reside in rural Defiance. I love working with my hands doing construction. My biggest passion is anything bow hunting and being outdoors.

PA Billie was very good about answering my question and him asking me questions. He explained what tests he wanted me to take and why I needed them. He had me wait at radiology to get the tests done. ...Show more
