Welcome to Escentia Ltd. I'm Paula Tully. There couldn’t be a more poignant moment to write my first blog for Escentia. I am sitting in a hotel in New York, entering year 4 of running Escentia.  The main view from my hotel is the Pfizer HQ and I start to think about how many times I proudly walked along 42nd Street to enter its doors, working with the best of the best in mind and in heart.
