Linda Specht, J.D.                                       

Interim Chair, Accounting

Photo of Linda SpechtI began my professional life as a CPA with one of the Big Four firms (KPMG), shortly after graduating from Texas Tech. I also later practiced law with the San Antonio office of Fulbright & Jaworski. I am proud of both affiliations, and the quality of practice of both firms is exceptional, but I was drawn back to teaching (which I had been doing intermittently since graduating from Texas Tech). I have been a part of the Trinity community since 1988.

Although I have mainly taught in the areas of accounting and auditing, I have had the opportunity to develop several courses on subjects about which I have been rather passionate: ethics, environmental accounting and auditing, and corporate social responsibility. I currently teach a course on the economy of communion, a model of corporate social responsibility and social entrepreneurship. I developed the course several years ago and teach it once a year. My research has centered on auditing, professional practice, accounting education, and corporate social responsibility.

Julie Persellin, Ph.D.

Director, Master of Science in Accounting Program

Photo of Julie PersellinMy professional career began as an auditor in public accounting for one of the large international firms. It was an incredibly valuable learning experience that sparked mydesire to educate myself further regarding the complexities of the financial accounting world. While in graduate school, I had the opportunity to serve as a teaching assistant for an undergraduate auditing course. That experience would prove to shape the trajectory of my professional career. I have been teaching for over 20 years, and still look forward to the new faces, as well as the challenges that each semester brings.

Bringing structure out of chaos, both in terms of teaching and my research, is a cornerstone of what I do as an academician. I encourage students to embrace the notion of inquiry as that is the foundation of learning. Having a sound base and structure allows us to think and be constructively creative.
