Dr. Michelle Gilpin Lopez

“Wherever the art of medicine is loved, there is also a love for humanity”(Hippocrates). I believe this quote captures the heart of family medicine as it should be; its roots firmly planted in a love for humanity, a love for human life from conception until natural death.

As a family medicine physician, I believe in a multifaceted approach to caring for the wholeness and uniqueness of the individual human person, I have furthered my traditional allopathic training with training in other areas including NaProTechnology, the Walsh approach to assessing and healing mental health difficulties. I have participated in research in the past, taught resident physicians and continue to research and problem solve for my current patients.

I believe in today’s healthcare climate, individuals need a healthcare advocate. As a family medicine physician, I both teach and advocate for my patients as they navigate the complexity of disease and seek to both achieve and restore optimal health.

It is a privilege and an honor to serve others as a physician of family medicine. I hope and seek to care for individuals as I would care for my own family. However, I truly believe it is ultimately the Divine Physician who heals each one of us and we as physicians are only His instruments here on earth, figuratively entering: “Into whatever houses (he/she) may enter...for the benefit of the sick.”

Dr. Michelle Gilpin Lopez is a board certified Family Medicine physician with over 20 years of experience and with additional training in NaproTechnology, Walsh Nutrient therapy approach to mental illness with applications in the treatment of Autism, Alzheimer’s and Parkinson’s disease. Dr. Michelle is currently completing fellowship training in herbal medicine. She has participated in research and has received the following awards: “Distinguished Teacher of Family Medicine” from Valley Baptist Family Medicine Residency Program in Harlingen, Texas and “Teacher of the Year” from Mosaic Family Practice Residency.

Dr. Edward Bayer

"What is a pediatrician? A medical practitioner specializing in children, treating their diseases, and promoting health. I became a doctor as I was fascinated by the human body. What God created was incredible. What can be accomplished through it is amazing. However, our bodies must be nourished appropriately: physically, emotionally and spiritually.

I became a pediatrician because children are our future. I felt I could make the most impact during this time in preventative health. It is a blessing to get to follow a child's development from birth to adulthood. I enjoy working with and helping teach parents how to instill healthy habits that their children can carry on into adulthood as preventative strategies for maintaining health.
To be an extension of the Divine Healer is a humbling honor to try to uphold. I always try to follow this philosophy: "I will always treat your child the way I want my children treated." The doctor/patient relationship is a sacred one. My job is to offer recommendations for you to then decide what is best for your child. I look forward to working with you."

Dr. Edward Bayer attended both undergraduate and medical school at the University of Wisconsin. Following medical school, he completed his residency in Pediatrics at Vanderbilt University Medical School in Nashville, TN. Following his residency at Vanderbilt in 1997, Dr. Bayer began practicing at what is now known as Ascension Medical Group (previously LaSalle Medical Group and Affinity Medical Group).

He was Department Chair for Affinity Health System Fox Valley from September 2005-06. He served as Lead Physician for Appleteon Pediatrics of Affinity Medical Group from 2005-2015. He has been a member of the UW Health Pediatric Advisory Council since 2005. He is also a member of the Children’s Wisconsin Fox Valley Community Physician Advisory Group.
