About Us

Opened by Dr. Armstrong in January, 2021, Immaculate Heart was founded with the mission to provide outstanding primary care services in a way that models the historic vision of Catholic healthcare. 

In February, 2022, our mission was further enhanced with the support and guidance of Bishop Thomas Olmsted, a partnership formed with the Religious Sisters of Mercy of Alma, MI, and Sr. Edith Mary Hart, DO joined the practice as our second family practice physician. Later that year Sr. Maria Crucis, RN joined us as well allowing us to provide an advanced level of care coordination and care delivery usually not possible in independent private practices. 

Immaculate Heart offers comprehensive primary care services to individuals of all ages. From newborns to the elderly, we will serve anyone in need of general medical care. We provide convenient appointments, same day availability, telemedicine appointments, and excellent customer service. Both Dr. Charles Armstrong and Dr. Margaret Hart (also known as Sister Edith Mary Hart), perform a broad variety of personalized medical services, common office procedures, and preventive health screenings, well-child exams, chronic disease management, and much more.

Feel free to schedule an appointment with us today. We want to help you achieve total wellness so you can feel your best!
