You don’t often think about your doctor until you get sick. Mercy Clinic Family Medicine and Obstetrics - Grande Center wants to change that. Being well between visits is just as important. So we focus on education and answering your health care questions and concerns, enabling you to take an active part in your health care. And Mercy Clinic Family Medicine and Obstetrics - Grande Center is part of Mercy Clinic – thousands of primary care and specialty care physicians in multiple states linked by a sophisticated electronic health record system. Everyone involved in your care will know your health history, past treatments and more.

Our doctors also offer MyMercy+, an app that allows you to view test results, make appointments, and send secure messages to your doctor and more –anytime and anywhere.

 
We've made it easier to reach us.

Our new, extended phone hours: 
M-F | 7 a.m. - 7 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.
