Allegiance Research Specialists - Milwaukee's Premier Independent Clinical Trials Site.

Whether you explore our site, complete our Volunteer Interest Form, visit our office, or speak with our experienced and passionate team of Leona Heffelfinger, Dr. Samuel Idarraga, Dr. Andrew Kim, or Melissa Voigt, you will have your expectations of service and care redefined.

We believe research must be conducted by professionals who are invested in more than just the work - It must be conducted by those invested in the outcomes and stories of the people who benefit from the resultant therapies.

We are honored to be your committed partner and tireless advocate.
