He began his medical journey as an AmeriCorps volunteer at the VIM clinic in Eugene, in 2006. The following year, he worked at Jasper Mountain/SAFE Center (residential and crisis treatment for psychiatrically complicated youth), and stayed there until 2009 when he went to New Haven, CT for medical education. After graduating from Yale he returned to Oregon, and was the first PA to join the psychiatry service at Asante’s Rogue Regional Medical Center, in Medford OR. For the first two years he focused on acute adult psychiatric inpatient care, often seeing patients after suicide attempts, or floridly psychotic during exacerbation of schizophrenia or schizoaffective disorder, or during severe manic or depressive episodes. Dan’s service expanded to outpatient treatment, emergency department evaluations, and Consult – Liaison work with other units, especially the Intensive and Intermediate Care Units. In 2016, Dan became a preceptor for Physician Assistant students from OHSU’s PA program, and felt very fortunate to provide his students in 4 weeks with so much exposure to different patients and conditions across the spectrum of Psychiatry. He leaves Medford on a high note, and is excited for this new chapter at OPP in his very favorite city, Eugene.
