A Message from Our Leader

Dear Residency Candidate,

The mission of the AdventHealth is to Extend the Healing Ministry of Christ, which continuously strengthens our commitment to healthcare. Our pharmacy team exemplifies this mission daily through teamwork, excellence in patient care, and continuous quality improvement.

Our PGY-1 residency program is in the pre-candidate status for the American Society of Health-System Pharmacists (ASHP) residency accreditation and we grow closer to our goal of full accreditation every day. We are one of the pilot programs selected nationwide to work with ASHP to determine best practices (i.e., early intervention, consultation) for implementation of a successful program.

Our residency offers a variety of clinical experiences to develop and further strengthen residents’ pharmacy knowledge, critical thinking, communication, and time management. We are proud of the clinical accomplishments of our pharmacists; most notably through our consultation services. Our antimicrobial stewardship program advanced significantly this year. We anticipate the addition of TheraDoc™ will further enhance our clinical practice capabilities. We are excited about the growth of our clinical services for TPN management, emergency medicine, and pain management. We are also excited to expand our transitional care services as we opened our new outpatient pharmacy.

Residents in this program will assist with improving current practices and have the opportunity to implement new processes. Upon completion of the program, residents will have the skills necessary to become independent and confident clinicians.

We appreciate your interest in our PGY-1 Pharmacy Residency program at AdventHealth Sebring. Please feel free to contact us with questions at any time.

About Our Program

AdventHealth Sebring is part of AdventHealth located in the heart of central Florida. It is comprised of 205 total beds across three campuses in Sebring, Lake Placid, and Wauchula. The Sebring campus will serve as the primary practice site for the residency program. The Sebring campus is the most active emergency room and the only Heart, Vascular, Stroke, and Chest Pain Center in Highlands County. We are a full-service medical and surgical acute care center with birthing services. Wauchula, a restricted access skilled nursing facility, is the area’s only transitional care unit and Hardee County’s only emergency department. We work very closely with providers to continually offer exceptional healthcare services to our community. Clinical pharmacists are integral members of multidisciplinary teams and are heavily involved in the inpatient management of pharmacokinetics, anticoagulation, and glycemia. Pharmacy is also represented on multiple system committees including corporate antimicrobial stewardship, P&T, Stroke, Code Blue, Readmissions, and Falls.
