  • "I have used TASA for the last five years for locating an expert for many personal injury cases. On each and every occasion, TASA was able to find me more than one qualified expert. With such a variety of experts, I was able to select one who met my client's needs in prosecuting these claims. I found the experts TASA referred not only qualified, but available on a moment's notice. Your fees are reasonable and fair, and I will continue to use TASA for the remainder of my career."


    Robert Oushalem, Esq., The Law Office of Robert Oushalem, San Jose, CA

  • "I recently used TASA for the first time to locate an expert to testify in a case requiring rather unusual expertise and where there were no applicable regulations or standards for guidance. TASA referred an expert in California who was everything a lawyer looks for in a forensic expert. He was promptly available for consultation, efficiently prepared for deposition and trial and very persuasive and credible with the jury. TASA's administrative services and assistance in locating this expert were excellent, and we would certainly use both the expert and TASA in the future."


    Theodore Phillips, Miller Hauser Law Group, LLP, Placerville, CA

  • "TASA has always given me first-class service, but in a recent matter, TASA found the 'needle-in-the-haystack' expert witness we feared didn't exist.   We needed an expert for a very narrow and limited issue in a very narrow and limited industry.  Because TASA has an extensive expert witness database, it was able to give us a referral almost on the spot.  It's why I always turn to TASA first."   


    Kathleen A. Herdell, Law Offices of Kathleen A. Herdell, St. Helena, CA

"Thank you for your quick response and the names of the two proposed experts. The situation that gave rise to our search for these experts has resolved and we will not need to retain them. However, we will continue to keep TASA in mind as these needs arise from time to time as your breadth of coverage for experts of all types is unparalleled, in my experience."

Bart W. Brizzee, County of San Bernadino, San Bernadino, CA

"We were involved in a case pending for more than five years with seven parties from three states. Three mediations failed before we looked to TASA for an expert. TASA referred an expert who clearly understood the complexity of the project and could effectively support his opinion. If it weren't for his expert advice and deposition testimony, the case would not have settled. Interestingly, the case settled within 90 days from the date this expert began."

Renee Colbert, Esq., Corporate Counsel, W.G. Tomko, Inc., Finleyville, PA

"Special thanks to our TASA referral advisor for her quick response to our initial request—we were extremely happy with how fast TASA was able to assist us! Your group does excellent work, and it is always my first stop when looking for an expert."

Susanne K. Sullivan, Senior Attorney, Southwest Airlines Corporation, Dallas, TX
