Many of you know Peter Roslow from his days on the client/media side. His experience as a buyer and user of research — in addition to many years as a research supplier — makes a difference. RRG provides a perspective that is valuable in survey design as well as in interpretation and application of research results.

Peter Roslow

Peter Roslow

Peter Roslow joined RRG in 1993, after tenures at Telemundo (as Vice President, Research) and Univision Television Group (VP, Sales and Marketing). Joining Telemundo at its birth, Peter built their research department and helped develop a number of syndicated services for the Hispanic market.

From 1983 to 1987, Peter was the Managing Director of Information & Analysis, Inc. (I&A), a research and consulting subsidiary of AGB. In addition to being Hispanic-market-specialists, I&A served a number of broadcast and cable clients.

Peter started in the marketing and research business in 1971 (No, it’s not a typo!) at The Pulse Inc.; and from 1978 to 1983 was a Senior Vice President at Strategy Research Corp. He has consulted for a number of public and private organizations and also currently serves as an adjunct Asst. Professor in the Marketing department at Hofstra Unjiversity.

Carmen Castro

Vice President

Carmen has been with RRG since 2002. Prior to joining the firm, Carmen worked in the publishing field (her specialty is art history); and worked for the Community Action Council (organizing classes for Hispanics; educating about social services and how to cope with living in the U.S.).

As a function of her interest in art history, Carmen has taken numerous classes at FIT and Adelphi and is also a Holistic Health Counselor. [Yes, she DOES try to get us to eat healthy and “live right” …but with limited success!]

Carmen oversees RRG qualitative projects, supervises fieldwork on several of our quantitative projects, and handles many of RRG’s questionnaire design and translation assignments.

Carmen is originally from El Salvador, having moved to the U.S. as a teenager.

Andrea Ospina

Research Associate

Andrea joined RRG in 2001. Originally from Pereira, Colombia, she holds a Bachelor’s degree in Graphic Design (plus an associate’s degree in Marketing) from the Universidad de Periera. Prior to coming to the U.S., Andrea had her own graphic design firm in Colombia.

Andrea started at RRG as a part-timer, handling phone-interview & editing/coding assignments. With this “hands-on” background, she now not only supervises our editing and coding departments, she also helps train new interviewers, and assists with project management.

Samuel Roslow

Director of Account Services

Sam brings many years of experience in marketing, sales and management to RRG; with particular emphasis in the financial services industry. He handles client relations and marketing, as well as managing selected research projects.

During his school days, Sam worked with RRG part-time in the data processing area. After gaining experience in the financial services industry, we were excited to have him back with us. He is involved in all aspects of marketing and account services, particularly in connection with financial services clients. Sam also helps with the design, set-up and tabbing of survey research projects.

Juan Carlos Maya

Juan Carlos Maya Consultant

Juan Carlos Maya joined RRG in 1998, after working at several major U.S. research firms (in addition to occasional stretches as a bartender and drummer in a Latin Rock band). His career as a marketing consultant and researcher began in Mexico …where — after attending Universidad de Cuautitlan Izcalli — he worked for Dueñas Galván y Asociados, a marketing consultancy in Mexico City.

Carlos has many years of experience with research project direction. He is also an experienced focus group moderator and assists with the data processing of RRG quantitative surveys. Another particular area of strength is his expertise with English-to-Spanish adaptations (i.e., for translating questionnaires and creative-concepts).

Marta Bethart


Marta Bethart is one of the most experienced focus group moderators in the U.S. She started in the marketing research field in 1980, and has been moderating Hispanic and general market focus groups for 20+ years now. Literally, she has conducted thousands of focus groups …on subjects as varied as home pregnancy tests and beer. An area of particular strength is with children and teen focus groups.

With her many years of experience directing projects and analyzing both qualitative and quantitative studies, Marta also occasionally assists RRG with overseeing other (non-qualitative) projects.

Marta graduated cum laude from the University of Miami in 1979. Born in Cuba and raised in the U.S., she is currently based in Miami, where she served for two years on the Board of the Florida Chapter of the MRA.

Cristina Bain Borrego


Cris is an independent consultant who — along with Marta Bethart — handles the majority of the focus-group/moderating assignments for RRG.

In our experience, the best way to learn moderation is to observe other moderators in action …both good ones and bad ones. As was the case with Marta, Cris started as a Spanish-to-English interpreter, observing thousands of groups over a 10-year period. Several years ago she made the transition from translator-to-moderator, and quickly became one of the best moderators we had ever observed. In the years since she began moderating, she has conducted many hundreds of groups: on subjects as varied as packaged goods, H&BA, automobiles, alcoholic beverages, politics, media and more.
