About Us


After treating a large number of Amish and Conservative Mennonites in his practice,  Dr. Edwin L. Nirdlinger, PhD, MD, became aware of the difficulty these patients had obtaining quality care at a reasonable cost.  In 2002, with the idea of helping Anabaptist communities, Dr. Nirdlinger along with Wolfgang Dresher, JD, LLM, formed the non-profit organization Immergrün, Inc.

At the present time, Immergrun is working to help Anabaptists obtain quality and affordable care near their homes. Establishing a working relationship between medical providers and the Anabaptists has proven beneficial to both parties. The Anabaptists leaders are very interested in working with and supporting their local providers and facilities.

There are several benefits for providers:

  • One entity to deal with
  • Immergrun pays 100% of contract allowed amount to the provider
  • Immergrun  handles patient inquiries
  • Directed patient care.  Immergrun patients are easily identifiable by the Health ID card they carry
