Donald A Porter


Don Porter has handled a variety of defense litigation over his 25 years with the firm, primarily personal injury related and involving everything from hot air balloon and power line accidents to the always changing field of vehicle and casualty litigation. He especially enjoys technical expert issues and "junk science" challenges to experts' testimony. Recently, he is changing his focus to develop greater efficiency in eDiscovery and lower costs to clients. These "technical" changes significantly lower litigation costs - at times making the difference between litigation being a viable option.

After graduation from the Universities of Notre Dame (B.A. Government) and South Dakota (law degree) he practiced as an Assistant US Attorney before joining Costello Porter Law Firm. He has been active in the State and Pennington County Bar Associations and a long time member of the defense bar associations in South Dakota and the national DRI. Always an advocate of efficiency gains through the use of technology in the law office, he has promoted office implementation of good networking and communication technologies.

Outside the office Mr. Porter and his family spend lots of time raising their three children and trying to stay physically fit so that they can keep up with their three children.
