About This Firm

Thompson & Colegate LLP traces its history to 1915 when the firm was known as Craig, Sarau & Thompson. These partners took office space in downtown Riverside, California. In 1916, Hugh Craig was appointed to the Riverside County Superior Court bench. Sarau & Thompson remained together for another 30 years, until 1947, when the firm took its present name of Thompson & Colegate.

The firm has played an active role in the legal life of the Inland Empire for over 95 years. It was instrumental in the growth of the desert communities such as the incorporation of the City of Palm Springs in 1938 and the formation of the Desert Hospital District.

Thompson & Colegate LLP is proud of its history of contributing members to the judiciary. Hugh Craig was the first alumnus of the firm to become a judge on the Superior Court bench of Riverside County. Hilton McCabe, Warren Slaughter, Robert Dauber, James D. Ward, Sharon J. Waters, Sherrill A. Ellsworth and Mac Fisher followed him from the firm to the judicial bench. Similarly, former firm alumni James Bishop and Joan Ettinger presently sit as Commissioners in the Riverside Consolidated Courts. Hilton McCabe and James D. Ward went on to appointments as Justices of the Court of Appeals.

The firm also has a long tradition of involvement in esteemed professional organizations. Tommy Thompson, Don C. Brown, Arthur W. Kelly, Bob Allen, and Don G. Grant and John W. Marshall were elected as Fellows of the American College of Trial Lawyers. Several members of the firm have also been elected to the American Board of Trial Advocates: Don C. Brown, Don G. Grant, J. E. Holmes III, John W. Marshall and Michael J. Marlatt.

Today, many members of Thompson & Colegate are active in the Association of Southern California Defense Counsel. Don G. Grant, J. E. Holmes, III, John W. Marshall and Michael J. Marlatt have served on its Board of Directors. Diane M. Wiesmann and Gary T. Montgomery are currently members of the Board of Directors. John W. Marshall served as President of this prestigious organization in 1996.

Thompson & Colegate LLP is an icon among Inland Empire civil litigation and business transactional law firms. Tommy Thompson and Roy Colegate have long passed on, but their firm is proud of its distinguished historical background and its ties to the Southern California community. True to the vision of its founders, the firm continues to provide its clients with the highest quality legal services and to maintain an unmatched reputation for professionalism and integrity within the legal community.

About Client Rating
About Peer Rating

Welcome to Martindale-Hubbell® Client Review, a new ratings service that allows you to view and provide feedback on a lawyer or law firm on service and relationship qualities such as Communication Ability, Responsiveness, Quality of Service, and Value for Money.

Determining a Rating

The Client Review Rating is determined through aggregation of validated responses. This compilation of Client Reviews translates to a numerical rating and associate descriptive term on a scale of 1 -5. 1 being lowest as "Rated" and 5 being highest as "Preeminent".

  • 4.5-5.0 Preeminent
  • 3.0-4.4 Distinguished
  • 1-2.9 Rated

Martindale-Hubbell uses a third-party resource to validate that the respondent is a living person, but cannot confirm the lawyer/client relationship, which in many cases is confidential. Clients must affirm that they are a client of the lawyer or firm identified for review at the time of the completed Client Review.

The Reviewers

Those who complete Client Reviews are clients of law firms who hired a lawyer within the last year, whose matter is not pending, and want to share their experience of that lawyer or law firm with other potential clients. Reviewers can be of any type from in-house counsel, corporate executives, small business owners to private individuals, and even sometimes another lawyer in a different jurisdiction.


Client Reviews are anonymous and reviewers' identities are not published; however a summary of basic demographics will be part of the display of responses.

Why do we collect demographics as part of the review?

Those who are researching a lawyer or law firm like to see that there are other clients who might be "like them". This is valuable information contributing to the decision-making process of hiring a lawyer.

Martindale-Hubbell's role

Martindale-Hubbell facilitates the process of Client Review by gathering responses, validating them and aggregating results for display online. The content of the responses are entirely from reviewers, the clients of the firm or lawyer.

It is important to note that Martindale-Hubbell does not undertake to develop Client Reviews for all firms and lawyers. Therefore, the fact that a firm or lawyer has not been reviewed should not be construed unfavorably. Prior results do not guarantee a similar outcome and Martindale-Hubbell accepts no responsibility for the content or accuracy of any review over which Martindale-Hubbell exercises no editorial review or control.
