Professional Experience
Carmel & Naccasha, LLP
- Current
At Carmel & Naccasha, my practice is split between litigation and transactional matters. I represent a wide range of clients including public agencies, local corporations, and individuals in business and employment litigation, real estate transactions, and business transactions.
Senior Associate
Goldman, Magdalin & Krikes
I assisted GM&K in developing a civil litigation practice at its San Luis Obispo County office. Although I enjoyed my time and the firm and worked with very nice and talented people, my time at GM&K was brief because I was presented with the opportunity to help Carmel & Naccasha expand its already growing litigation practice.
Court Attorney
San Luis Obispo County Superior Court
At the SLO County Court, I was fortunate to work directly with the County's judges and, particularly, our judges assigned to the civil calendar. I assisted the judges on law and motion matters by researching and preparing memos with recommendations on contested law and motion matters. I also sat pro tem on occasion when judges or commissioners were away, hearing law and motion calendars, case management calendars, and small claims.
Senior Counsel
Pacific Telesis Group
At Pacific Bell legal, we kept most litigation in-house and I worked on a variety of cases from complex business litigation to simple personal injury and property damage cases. On larger cases, including class actions, I also worked with outside counsel to ensure that the company's interests were protected.
Senior Associate
Haight Brown & Bonesteel
At HBB, I was fortunate to work in a litigation department with some of best trial attorneys in the state. I was also given tremendous autonomy from the start and allowed to run cases from start to finish. While there, I learned a tremendous amount about the practice of law and life in general from partners like Bill Baumgaertner and Peter Ezzell.
