Dr. David Bledsoe is an expert in all phases of veterinary pharmaceutical development and has spent the majority of his career leading clinical research products for FDA, Center for Veterinary Medicine (CVM) regulated products.  He is experienced in all FDA-CVM regulations regarding drug development, Good Laboratory Practices (GLP), Good Clinical Practices (GCP), Good Manufacturing Practices (GMP) and pharmacosurveillance.

​

​David’s career is a mix of working in Industry and in private practice as a veterinarian.  The later part of his career has been in Industry working for both large and small animal health companies before working as a consultant.  He currently consults with the Scullion Strategy Group and he is also the Managing Director of Qualitas BioSciences, LLC.  Prior to consulting, he was the Director of Clinical Research at Nutramax Laboratories, the Vice President of Specialty Practice at Animal Clinical Investigation (ACI) and was the R&D Project Manager at Central Life Sciences, formerly Farnam Companies. He also held field veterinary positions for companies such as, Bayer Animal Health and Novartis Animal Health.  

​

Prior to joining the veterinary pharmaceutical industry, he had had several roles in private practice in the state of New Hampshire in small animal and emergency medicine.

David has taken formal short courses in Veterinary and Comparative Pharmacokinetics, GLPs for Study Directors and Monitors, and managing Compliant Veterinary Clinical Trials (GCPs), as well as being media trained.  David enjoys writing, both professionally, as a technical writer, and personally.  He has been privileged to work with some of the leading researchers in several clinical areas and his list of publications is extensive.  Outside of drug development, his areas of clinical interest include veterinary behavior, dermatology, internal medicine, parasitology, pain management and models of anti-nociception.

David is a member of American Veterinary Medical Association, the American Academy of Veterinary Dermatology, the and was a former board member of the National Commission on Veterinary Economic Issues  Sponsor’s Council. He is also Board Member at Large for Not One More Vet, Inc, (NOMV) a peer-to-peer support group for veterinarians dedicated to mental health and wellness in the veterinary profession. David is also an Administrator for NOMV’s 15,000 member Facebook page.

​

Although David resides in Arizona, he still maintains a veterinary license in the state of New Hampshire.  He holds a Doctorate in Veterinary Medicine from Virginia Polytechnic Institute and State University in Blacksburg, VA and a Bachelor of Science in Biology from Frostburg State University in Frostburg, MD.
