During the last year, our practice made the bold attempt to integrate full psychiatric care for our patients. Also during this time, several community practices closed and Trinity inherited many new patients. Therefore, the combination of adding a new specialty to the practice along with managing a tremendous increase in medical patients has created many unforeseeable challenges to the practice. This has been extremely difficult to navigate and at this time, it has been mutually decided that our psychiatric services will be referred to a specialist team of providers. This also means that Linda Olivere, PMHNP-BC, our psych provider, will be moving on as well. She will be heading to Christiana Care Concord to provide ongoing psychiatric care. That site also has a primary care practice for those patients that choose to have all services in one setting. Patients desiring psychiatric care may call Christiana Care after August 9th to schedule appointments beginning September 6th with Linda Olivere. The number to call is 302-320-2100. We wish Linda all the best in her future endeavors and thank her for the commitment she has shown to the Trinity patients in providing exceptional care.
