The ASHP-accredited PGY1 pharmacy residency program at Corewell Health William Beaumont University Hospital has been training residents since 1977. Each year, the department of pharmaceutical services accepts six new PGY1 pharmacy residents into the program. Our department also offers a 2-year non-traditional PGY1 residency program (started in 2013) to pharmacists who have been employed with the department for a minimum of 1 year. The PGY 1 program strives to meet the needs of the resident based on previous experience, pharmacy practice interests and individual goals of the candidate. The 54-week program begins in mid-June and ends the following June.
A PGY1 Residency at Corewell Health William Beaumont University Hospital will provide residents with:
Corewell Health William Beaumont University Hospital is ranked No. 2 in the state of Michigan with 9 national rankings, one high performing specialty, and 21 high performing procedures and conditions by U.S. News and World Report in their 2025 - 2026 Best Hospitals rankings.
The purpose of the ASHP-accredited Corewell Health William Beaumont University Hospital post-graduate year one (PGY1) pharmacy residency is to build on doctor of pharmacy (Pharm.D.) education and outcomes to contribute to the development of clinical pharmacists responsible for medication-related care of patients with a wide range of conditions, eligible for board certification, and eligible for postgraduate year two (PGY2) pharmacy residency training.
The PGY1 residency program at Corewell Health William Beaumont University Hospital will foster the development of competent and confident pharmacists. As a member of the health care team, residents will be responsible for providing direct patient care to multiple populations. They will exercise skill in educating health care professionals and patients on medication related topics. Residents will solve practice-related problems in a time sensitive manner through critical thinking skills. Residents will demonstrate professional maturity by following a personal philosophy of practice, monitoring their own performance, exhibiting commitment to the profession and exercising leadership in improving the safety of the medication use system. Lastly, residents will possess the knowledge and leadership skills to promote the advancement of the practice of pharmacy.
The 54 week long residency program is divided into eleven one-month experiences following a six-week orientation dedicated to operational areas and clinical services. Refer to the "rotations" section for required, selective, and elective learning experiences. PGY1 Residents at Corewell Health William Beaumont University are also required to complete a number of longitudinal requirements.
*Program requirements are subject to change at the discretion of the residency program director and RACS
*Approved financial support for travel to conferences is at the discretion of the organization.
Our inpatient pharmacy department utilizes an integrative practice model, where pharmacists have responsibilities for both distributive and clinical functions. Advancement of our practice model includes the incorporation of state-of-the-art technological systems and a comprehensive electronic medical record.
Ambulatory care pharmacy services include: anticoagulation, diabetes, transitions of care management, pharmacist clinic (collaborative practice agreement to provide medication management for patients with diabetes, hypertension, hyperlipidemia, asthma/COPD, smoking cessation, etc.) and infectious diseases clinics.
Our residency preceptors are actively engaged in practice, education and scholarship. The majority of preceptors hold adjunct appointments with Wayne State University, Eugene Applebaum College of Pharmacy and Allied Health Professions, the University of Michigan, and/or the Oakland University William Beaumont School of Medicine and enjoy productive collaborative relationships with these key partners.
In recognition of their accomplishments, members of our pharmacy team have received external recognition of excellence at the local, state, and national level. Our preceptors hold fellow status within national professional organizations as well as discipline-specific and specialty board certification.
Additional awards include:
The PGY1 residency program at Corewell Health William Beaumont University Hospital consists of seven required learning experiences, at least 1 selective learning experience, up to 3 elective learning experiences, and several required longitudinal learning experiences. Residents may repeat any learning experience as an elective (with the exception of orientation and internal medicine).

Program extension may be considered, and residency training plans may be modified to accommodate licensure delays, including but not limited to, adjustments to staffing, on-call and rotation schedules. If the resident is not licensed within 120 days after the program start date, the resident will be dismissed from the program.
