I have used David’s services as a contract researcher for over 10 years and he continues to be one of the most professional and capable people I work with.  David is great about his attention to detail with protocols as well as providing input on how to improve my trial protocols.  He has always managed each trial perfectly.  With all that said, my favorite thing about working with David is that not only does he do a great job with the trials, he also provides a high level of professional and market insight about the crops and materials I am working with.  This has proven to be invaluable.  I really appreciate David and honestly look forward to seeing which trials I will be able to work together with him on each year.
