Petersen Johnson Legal Team

Petersen Johnson Legal Team

Petersen Johnson Attorneys

Petersen Johnson was founded in 1996 by personal injury attorneys Ron Petersen and Brad Johnson. The firm was built on the premise of providing the attention and devotion of a small firm with the resources and capabilities of a large one. Clients get to work directly with a partner on every case, but the entire team at Petersen Johnson provides support and is dedicated to helping personal injury victims get a fair settlement. Each team member has dedicated years of service and is fully committed to upholding our mission and values.

Bradley K. JohnsonPartner/Founder

Brad, a founding partner at Petersen Johnson, has practiced auto accident and injury law since 1990. He is a champion of the underdog and receives a tremendous amount of satisfaction from helping people after a traumatic accident. His passion for personal injury law is evident in everything he does, from his tough and direct negotiation style to his commitment to his clients. In fact, Brad championed our pledge to get clients in front of a lawyer within two hours for initial meetings.

After growing up in Illinois, Brad went to Arizona State University for his undergraduate before getting his Juris Doctor Degree from Creighton University. He is a member of the Arizona Bar and a Board Member of the Happily Ever After League, a network of support services for moms with cancer. Outside the office, Brad spends much of his time with his wife, Marla, and their two children.

Ronald D. PetersenPartner/Founder

team Ronald

Ron is a founding partner of Petersen Johnson and has been practicing law since 1980. His fascination with the legal field began early in his life when he realized knowing the law allows a single individual to stand on equal ground against even the biggest institutions. This led him to choose accident injury law, as he could help protect individuals and their rights against large insurance companies. He received his Bachelors and Juris Doctor degrees at the University of Nebraska-Lincoln and is a member of the Nebraska and Arizona Bar.

Ron’s commitment to client service is the driving force for many of the extra benefits Petersen Johnson brings to its clients, including the 25 percent discount fee. When away from the office, Ron enjoys spending his time with his wife, Jennifer, and their three children.

Lisa West

Hard work and passion is what has driven Lisa to where she is now. Starting out as a receptionist, she has experience as the first point contact for clients needing legal representation. Her drive opened doors for her to become a legal assistant, and eventually, a negotiations assistant. Her top priority is the bottom line for our clients. She makes sure to dot the I’s and cross the T’s to ensure that at the end of the day, clients are happy and know we made every effort to get them the best possible outcome for their case. Outside of the office, this Arizona State alum prides herself on being a true, diehard ASU Athletics fan. Sun Devil for life!

Susan West-McGraw

Susan has more than 20 years of experience in the legal field and has spent most of that time as an employee at Petersen Johnson. Susan works closely with Brad on some of the more complicated cases and helps him with the intake process. As a social butterfly by nature, Susan loves working with clients because it gives her a chance to meet and speak with new people on a regular basis. Her personal life is dedicated to her husband, three children and two grandchildren, but she also recently became scuba-certified and plans to enjoy her new hobby as often as possible.
