Establishing a relationship with a Mercy primary care provider, or internal medicine physician, is the most effective and efficient way to manage health care for you and your family. We treat adults of all ages, including geriatric patients. We look forward to working with you and managing your health care needs.

We've made it easier to reach us.

Our new, extended phone hours: 
M-F | 7 a.m. - 5:30 p.m.
Sat | 8 a.m. - noon

While our care team is still available to answer your medical concerns 24/7, we're extending our phone hours for non-medical needs, too. Call to schedule an appointment, request refills and more during our extended phone hours. Or use your MyMercy app or mercy.net anytime.

After-hours medical concerns?

Before you go to the ER, call your primary care office nights and weekends for guidance from a full Mercy care team.
