I have worked with Donna Hartzfeld, Ph.D. at several companies and have found her to be professional, knowledgeable, and very proficient in medical device manufacturing practices. At Biomerics, she offered consulting services to prepare us for a combination medical device/pharmaceutical product. Her knowledge was useful in creating a gap analysis for quality system implementation. At MedPlast, She was invaluable in writing quality system documentation and improving our quality system. She was very thorough and professional in handling difficult situations and personalities. She also produced excellent quality work in a short period of time, which aided us in meeting our system deadlines. At Katecho she performed our ISO/FDA internal quality audits. She was flexible in handling our audits with very little notice and identified key areas to address our quality system deficiencies.

Dr. Donna Hartzfeld is an experienced consulting professional who has effectively led many teams in the areas of quality systems development, validation, and warning letter response. I have worked with Donna on multiple past projects in the medical device, OTC, and pharmaceutical industries and I would work with/for her again without reservation. She is a valuable asset to any project requiring technical knowledge, regulatory knowledge or skilled leadership to meet critical task deadlines.

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.

Donna has been both adviser and regulatory consultant to Mission3. In both capacities she has been professional, knowledgeable, and thorough. Her ability to find the right answer and do work with incredible level of quality makes her an incredible asset to any team. She is personable and easy to work with
