Announcement to Our Patients!

Starting April 29th until early-mid September, there will be construction on Lawrence Drive which will cause detours to and from the St. Gianna Clinic. The City of De Pere will be reconstructing both the north and south bound lanes of Lawrence Drive. Stage 1 will be April through June and will begin with the north bound lane.

See what our patients have to say!
I've been a patient of the St. Gianna Clinic since its opening. I can say without a doubt, they are TRULY excellent and ALWAYS faithful!
I endured a very complicated and risky pregnancy with my ninth child. Dr. Madeleine Guevara of the St. Gianna Clinic took the best care of me. At 23 weeks and 4 days, she urgently delivered my son and meticulously ensured safe medical care afterwards for both of us. I have no doubt that St. Gianna Clinic saved both my life and that of our then preborn son. My husband, children, and I continue to be grateful to the St. Gianna Clinic that my son and I are here today!
It has been a long, long time since I really felt like I was getting care by a doctor/team that genuinely had my best interests in mind. Unlike the medical system most people are stuck in, St. Gianna is progressive, engaged, and genuine.
Thank you for being there.
My needs are taken seriously, both as a Catholic and as a patient. I don't have to question the advice that I'm given; they won't just put a bandaid on the problem, but will help you find real healing. They genuinely love and pray for every person that comes through their doors.
I have never had a bad experience at the St. Gianna Clinic. It's such a peaceful place, and the staff and physicians have the professional knowledge and openness to the Holy Spirit that allow them to offer the best care you're likely to experience anywhere. If you haven't yet, come and see this place for yourself.
My husband and I went 3 years with no answer to our question. We asked God, "Will we ever get pregnant?" Due to the unique care plan, progressive medical science, and specialized guidance from the St. Gianna Clinic, we welcomed baby John to the world September 19, 2018. Since then, we have welcomed Kathryn, and Olivia. We are expecting our fourth miracle baby due at the end of February 2024.
Our kids see Dr. Bayer... He's a superman doctor. Words of my kids. In our eyes he is the best of the best... Thank you St. Gianna for getting him as a doctor. Thank God people can have a pediatrician like Dr. Bayer.
Everything about the practice has been amazing. It took years for me to find and obgyn that aligns with our values while also PROVIDING excellent care. From the moment you make an Appointment until you walk out the door, you are well cared for.
