What People Are Saying

I have had the distinct pleasure of working with Gualberto on several research articles on which we collaborated. He was an amazing source of therapeutic and clinical trial guidance expertise. He was immensely responsive with answering clinical questions on best practice, site ownership and patient recruitment. He is unique in that he is a physician entrepreneur, who has also served as a successful PI, and early phase innovator. He is my go to for complicated clinical research questions, for he is kind, professional and incredibly knowledgeable. He has helped me create content and contributed to several articles I have written. I look forward to every collaboration with him.

There’s always one guy that stands out when you look back and try to figure out who is a true expert in a given area, for me that is definitely Gualberto. When we first met, he was handling special populations and patient access more than a dozen years ago, and to this day I have yet to meet his equal…. compassion, in-depth understanding of R&D, experience and an analytical mindset, and rolled up with an immense passion for his line of work makes for a true innovator! Even though it has been many years since we have worked together for the same company, he is always (by far) the first one I will think of to consult with when challenges arise in his areas of expertise, a true asset to the field.
