About PDF Sages

Widely recognized as one of the leading experts in the field of PDF document processing, Leonard Rosenthol has formed a company to apply his unsurpassed experience and skills toward the growing need for custom PDF-related development. Leonard has also brought with him the services of many of experts in the field.With more than 30 years of combined experience in the computer industry and 10 years of that time dedicated to PDF, PDF Sages can smoothly handle the most demanding development work.

"At a time when Adobe Systems has achieved a 41 percent annual growth with its Acrobat® business, the need for PDF consulting services has never been greater. In my opinion, Acrobat is a monolithic product -- navigating the thousands of pages of PDF developer documentation requires either a crystal ball, or better, someone who can both talk and walk PDF. Leonard's detailed knowledge of all things Acrobat and PDF -- at the highest and lowest levels -- has rightly earned him the title of guru at PDF-focused industry conferences and more importantly, labelled him as someone to whom others should -- and do -- listen. I would recommend them without hesitation to anyone looking to embark on a PDF project." Karl De Abrew, CEO of BinaryThing/Planet PDF.
