Nancy K., Director of Strategic Planning, Anderson DDB Health & Lifestyle

Over the past 20 years, I have worked with Sarah Greenberg as a client, a colleague, and a fellow supplier. On every occasion, Sarah has been exacting and committed to excellent client service. She's one of those people who will exceed your expectations every time; you will want her to handle your most important projects. It's no accident that some of the best people I've worked with in research in Canada were trained by Sarah Greenberg.

Anik K., Principal, Rank Research Group Inc.

I've worked with Field Source on many projects over the years. They are always very conscientious and do great work. From the hardest to find respondents to insane turn around times Field Source always seems to manage it.

Benjamin, Global Operations Manager

Since the very initial establishment of our business relationship, Sarah Greenberg and Fieldsource have played an integral role in supporting Frost & Sullivan's custom research unit's data collection needs. No matter whether it is for fieldwork end-to-end solutions, support with hard to reach respondent groups or complete process outsourcing. Based on our experience, Fieldsource is probably one of the most reliable and flexible partners in this industry.

Gray H., Director, BrandWright Inc.

I've worked with Sarah Greenberg for over 20 years. She's our project manager for major surveys & focus groups. Sarah's driven by her intense passion for market research. She stays abreast of industry knowledge and always adds valuable ideas to our process. She delivers on-time and on-budget.

Ruth L., President, RML Research

I have known Sarah Greenberg for more than 20 years -- in her capacity as Field Manager for large suppliers and as an independent field supplier. She has delivered a consistent and high level of service regardless.
