Mr. Ingalsbe is one of the firm’s senior litigators with over 42 years of experience in the courtroom. Although he specializes in public and private construction law, he also has tried numerous general business and civil cases, including large, complex business disputes, employee wrongful termination, and personal injury cases. He has litigated and tried cases in both state and federal courts throughout California and other states, as well as matters before state and commercial arbitrators.

In recent years, Mr. Ingalsbe has actively represented concrete suppliers in major sulfate and mold litigation and participated in the first sulfate trial in California. In 2005, he was the defense trial attorney in the Orange County, California case known as Castron v.

Mr. Ingalsbe’s extensive experience in construction and construction defect litigation has made him a nationally sought-after speaker. He has participated in seminars and workshops for such groups as the National Ready Mixed Concrete Association and the California Construction Material Association, as well as for numerous private and corporate sponsors. He continues to speak, both nationally and to local industry associations, on issues facing the construction industry as a result of recent court decisions and newly enacted legislation.

As a well-respected trial attorney, Mr. Ingalsbe has earned the reputation as a tenacious lawyer, who has the proven ability to manage and try large and complex cases. He has gained the respect of his peers, receiving an “AV” rating by the Martindale-Hubbell Law Directory.

Mr. Ingalsbe is a member of several professional organizations, including the Orange County Bar Association and the Legal Advisory Committee of the Associated General Contractors of California. He is admitted to practice before all state and federal courts in California and both the Ninth Circuit Court of Appeals and the United States Court of Federal Claims.
