Justin M. Gingery

Partner | Trial Attorney


Justin M. Gingery leads the litigation department of Gingery Hammer & Schneiderman LLP. Since passing the California Bar Exam in 1999, Mr. Gingery has represented clients in civil litigation matters with an emphasis on personal injury, wrongful death, product liability, civil rights, public entity and premises liability.

Mr. Gingery has been incredibly fortunate to have some of the best mentors in the legal profession throughout his career. One in particular taught him the importance of making the following commitments: You will be provided with his direct phone number and his email address so you can reach him whenever you need to. In the event you call him during the day and he is unavailable, he will return your call that same day, or first thing the following day. He will always do his best to get back to you the same day. If you have any questions or concerns about your case, he will spend whatever time it takes to make sure you get an answer that you are comfortable with. There are no stupid questions and no questions are off-limits: He wants to know what concerns or worries you. Unfortunately, his answers may not always be positive. As the client, you have the absolute right to know both the strengths and the challenges of your case. He believes that it is not enough for you to know what is happening, but also why. The law can be illogical and intimidating, and it is his job to help you toward an understanding of the legal and factual issues in your case. In dealing with your case, he will listen to your concerns. This is your case, and you need to feel comfortable that you are being helped by a lawyer who tries to understand what you are going through.

Daniel Schneiderman

Partner | Trial Attorney


Daniel Schneiderman was born and raised in Sacramento, California. After graduating from Jesuit High School he attended the University of California, Santa Barbara, where he worked as an intern for the Santa Barbara District Attorney’s Office and Attorney General’s Office for the District of Columbia. He would later graduate magna cum laude with honors with a major in political science and a minor in history.

Mr. Schneiderman earned his Juris Doctor at the King Hall School of Law at the University of California, Davis. There he earned a position on King Hall’s Trial Practice Honors Board while working as a law clerk for the personal injury law firm Dreyer Babich Buccola Wood Campora LLP. He would later work as a certified legal assistant for the Sacramento County District Attorney’s Office before being sworn in as a Deputy District Attorney in 2013. 

As a Deputy District Attorney, Mr. Schneiderman prosecuted criminal cases to jury trial while managing a rotating caseload of over 50 misdemeanor complaints. He eventually returned to Dreyer Babich Buccola Wood Campora LLP as an attorney, where he maintained and litigated 60 to 80 personal injury cases at a time as both 1st and 2nd chair in California state and federal courts. These matters included numerous complex, high-stakes personal injury cases, many of which resulted in six to eight figure trial verdicts, arbitration awards, and settlements. 

Today, Mr. Schneiderman continues to grow his practice, using his wealth of litigation and trial experience to represent and advise plaintiffs who have been wronged in personal injury disputes through mediation, arbitration or trial in both state and federal court. For his work, Mr. Schneiderman has been rated by Super Lawyers magazine as being in the top 2.5% of attorneys under 40 years old, receiving the Rising Stars Award for his performance in civil litigation and personal injury in 2016, 2017, 2018, 2019, and 2020. Mr. Schneiderman has and continues to work towards providing his clients with an open and transparent attorney-client relationship, an effort that has earned him a “5 out of 5” star average client review and rating of “10/10” on the attorney review website 

When Mr. Schneiderman is not working you can usually find him trying to get to the beach for a surf, hanging out with his wife Vicki and three pets, or laying in his hammock in the backyard. He continues to strive to offer the best possible representation in the field of personal injury throughout the San Diego, California, and federal court systems.

He has been involved in numerous serious personal injury litigation matters that have resulted in multi-millions of dollars for the victims. A member of the Trial Lawyers College, Mr. Allard is dedicated to representing and obtaining justice for those that are injured from the careless acts of others.

A former Sergeant in the United States Marine Corps, Mr. Allard served four years at Marine Corps Base Camp Pendleton serving as the Wire Chief for Marine Air Control Squadron 1.

Mr. Allard ultimately received his Bachelor of Science degree in Industrial Engineering from Oregon State University and was awarded his Juris Doctor degree from the Thomas Jefferson School of Law.

The one thing that resonates with all of these attorneys and what prompted Mr. Allard to ultimately decide to work with Mr. Gingery at the Gingery Hammer & Schneiderman LLP is that all of these men put their integrity first.
