“First I would say that CSRS is highly professional. This includes meticulously evaluating various options for the research along with their associated costs. Interviewer training and supervision are also a big part of their professionalism.  A third aspect of CSRS professionalism is the quality of the data I have received. Verbatim responses were detailed; the SPSS file faithfully adhered to the questionnaire.  The sample disposition data were comprehensive.

CSRS in general, and Ken Gross particular, is very much a research partner. The various studies I have worked on with CSRS began with creative discussions about sampling alternatives and measurement issues. In my experience it has been very common for CSRS to anticipate situations and response that never occurred to me.”

“The California Survey Research Services (CSRS) is an outstanding group of professionals who conduct telephone interviews for the purpose of gathering research data. The California Survey Research Services utilizes the latest computer assisted survey technology and provides culturally competent interviewers. My experience with CSRS has been most gratifying. The personnel at CSRS assisted us from beginning to end in tailoring our telephone surveys with the highest scientific rigor. The quality of the data and their timing in the delivery of the data was outstanding. What is most important was the accessibility to Mr. Ken Gross, president of CSRS, who was of great help in solving problems or making needed changes to the surveys.  Also, the cost of working with CSRS was significantly lower than other similar outfits in the region. I give CSRS my highest recommendation without reservations.”

“CSRS is a team of highly qualified professionals who are affable and possess extensive survey research knowledge and skills.  The team is led by an extremely well organized and compulsively thorough individual with more than 30 years of experience in the field.  CSRS has the manpower and the material to implement small to very large surveys in a short timeframe.  As an assistant professor at a medical and health professions university, I have engaged CSRS to conduct surveys and have been extremely impressed and totally satisfied with the quality and timeliness of their work.  I would highly recommend CSRS to anyone in need of survey research.”

“I would describe CSRS as extremely reliable, creative, understanding of the needs of scientists, healthcare professionals, and the demands of the federal bureaucracy, meticulous, professional in every way. Our dealings with CSRS could not have been better. Deliverables were on time, and working with everyone there, bottom to top, was a joy.”
