"I can truly say I have my dream job. I work and live in a wonderful community, where I interact with my friends' and neighbors' children. Watching these kids grow up has been a joy, and I hope someday I will take care of those patient's kids! Now that I have kids of my own, I really enjoy the conversations with my patient families as we raise our kids together. I think of it as an on-going conversation we will be having for the next eighteen years."
Dr. Rose-Stine's husband, Matthew Stine, is a family physician in Willow Park. The couple met in college and married in medical school. They have one daughter and one son. Dr. Rose-Stine enjoys being outdoors, reading, running, and chocolate.
