The Professional Development Network (PDN) program was implemented to enhance mentoring and learning opportunities for dietitians at a multisite health care organization. Program development, implementation, and evaluation were carried out by a Professional Practice Council composed of dietitians in the organization. An exploratory evaluation was conducted after the first year of PDN implementation. Evaluation data were collected from an online survey containing open- and closed-ended questions and PDN documents submitted by dietitians. Data were analyzed with descriptive statistics and thematic analysis. Survey results indicate the PDN provided a mechanism for dietitians to learn from each other, apply learning to their career development, reflect on their strengths, and connect with others in the department. Analysis of PDN documents showed that dietitians pursued learning related to clinical practice, technology, private practice, and research. Mentoring interactions were also described by participants within PDN documents. Findings from this study demonstrate how multiple frameworks from academic literature can be integrated to create a professional development program in a dietetics practice environment. Evaluation results from this study may provide useful insights for others interested in implementing professional development programming.
