We recently worked together as part of a team to improve and reduce Lab Investigations for a client. Dr. Hartzfeld showed good problem solving skills and excellent technical competence in doing the Lab Investigations. Her communication skills in writing and verbally are very good.
Certainly when you retain a regulatory affairs consultant, you look for subject matter competence. Donna goes well beyond that, offering company-specific advice, understanding time sensitivity, and providing the care needed in a start-up environment. I strongly recommend her.
Donna has provided timely and effective quality management consulting to my firm over the years. She is both very knowledgeable and personable, making interacting with her productive and enjoyable.
Dr. Donna Hartzfeld, and her company QIS, have been consummate professionals in every task. She has proven not only to be extremely knowledgeable technically, but also an expert in client relationship management. Dr. Hartzfeld is the first person I call whenever I have need of a qualified and dedicated scientist.
