The founders of Greylock Press, Mark Danderson and Beth Johnson have worked in medical publishing for over 30 years. Their work together began in the early 1990s at the New England Journal of Medicine (NEJM). Beth and Mark were responsible for establishing the International Sales and Marketing Division at NEJM. Collectively they have over 30 years of experience selling to the pharmaceutical industry on a global scale.

After their work together at NEJM, Beth and Mark’s careers took separate paths. Beth was the co-founder MD Conference Express the first peer-reviewed medical conference highlights report. While Mark went to work for a publication owned by the Chinese Ministry of Health developing medical educational programs for Chinese physicians.

Fate reunited them in early 2015. While sitting around the table at the Langer family farm located at the base of Mount Greylock in Western Massachusetts (the inspiration for the company name), discussions turned to the difficulty of keeping up-to-date on the latest developments in medicine in general and in the pharmaceutical and medical device industries in particular. Ironically, in many ways, the internet has made keeping up-to-date more difficult. Our lives are busier and we are flooded with information, but we have less time to digest that information making it nearly impossible to discern useful knowledge from clutter.

From this discussion was born our first idea – the Pharma Development Digest (PPD). The impetus for PPD  is simple yet innovative. As experienced sales people, Beth and Mark understand the importance of having timely information that imparts useful knowledge about the factors that drive pharmaceutical marketing efforts. A credible source of concise, timely, market intelligence would lead to more focused, strategic, and productive sales efforts. From this simple concept PDD  and the Greylock Press motto were born:

Knowledge | Strategy | Prosperity

PDD  provides only the information that is germane to pharmaceutical product development. The concept was to design a time saving product that would provide concise, accurate information about where the industry is currently focusing its efforts and how individual company efforts fit into the industry as a whole. Conserving the time, efforts, and expense of sales and marketing staff by assembling the information in a format that allows the reader to quickly discern which products are priorities for their clients and in which market segments efforts should be focused.

Our mission is to distill and organize market intelligence related to the healthcare industry, providing products and services that transform information into actionable knowledge to help our customers and clients realized their strategic objectives and achieve prosperity.
