"I can always count on Robert for help with complex criminal matters. I appreciate the personal service and long hours he's invested in my cases."

Michael Phillips, Attorney at Law

"I've been a criminal defense attorney for 30 years.  My practice is focused on serious and complex trial litigation.  I've exclusively used Mr. Beresford as my investigator for over 17 years.  Quite simply, I wouldn't trust anyone else.  I have referred him to several colleagues and the response has always been the same - they are impressed with his work ethic and professionalism.  Robert is very diligent and detail oriented.  Once we start working on the case, he is a self starter, and time and time again he finds things that I never thought of. However, I think what I appreciate the most is his assistance at trial.  Whether it's finding witnesses, running background checks or creating trial exhibits.  And when he's testified, he is always extremely well-prepared and juries find him very credible and professional.  Bottom line, Robert is a top-tier investigator who is committed to helping you succeed."

Thomas Daly, Attorney at Law

"Robert has demonstrated extreme patience with even the most difficult clients. He has also provided thorough investigation results and well written reports. No stone is left unturned."

Jennifer R. Walters, Attorney at Law

"Whether criminal or civil, I can always depend on Robert to deliver the information I need to obtain the best possible result for my clients."

Ken McCormick, Attorney at Law

"I'm a retired Contra Costa County prosecutor who is now an owner of a law firm in Walnut Creek.  On a number of occasions, I have hired 'Beresford Investigations' to interview people and collect information about civil and criminal cases.  Mr. Beresford has done an excellent job for me.  His reports are clear and concise.  He understands the issues, he is smart, and respectful to the witnesses.  Yes, I recommend him as a private investigator."

James Granucci, Attorney at Law

"Robert conducted a months long investigation regarding a felony battery case in which a father and son were charged; multiple teen-age victims were alleged.  A lengthy trial followed and the jury acquitted both. Robert has also assisted me with a murder investigation and other complex criminal matters.  His witness interviews are thorough and he has demonstrated a high level of attention to detail."
