I'm going on probably 15 years of working with Product Safety Labs on various projects, some small and some very big, and by no means is the following meant to be an oversight of the pleasurable dealings that I have had with the various employees at PSL. Everyone has been both courteous and professional with every Email and phone call that I have made. However, I would feel quite guilty if I didn't single out the assistance Jennifer Durando has been to ###### over the past several weeks. In a nutshell, we have several studies to complete and submit to the EPA quickly. Not an impossible task, but very difficult considering the testing required and the limited amount of lab space available. As difficult as it may seem, I was set to run a pivotal study starting next week, until it was decided that we needed to run additional tests before the formula for that study could be selected. In a panic, I called PSL and Jennifer was chosen as the person to deal with the hysterical client on the other end of the phone. Once I explained our situation, she said not to worry and if she received the samples within the week, we would have our results in time for our next study. She also advised us to run the studies GLP in that if successful, we wouldn't need to rerun in the future. We were able to get the samples down in time, Jennifer got the study up and running last week and as promised she was able to provide us with the results this morning. Granted, this project still has quite a few hurdles left, but without Jennifer (and yes I realize that there were others involved - and to them I also give my deepest gratitude) this project may have been delayed for another 6 to 12 months.
