In business for more than 25 years, Arrowhead Evaluation Services, Inc. (AES) was started in 1987 by orthopedic surgeon, John McAllister, M.D., a popular Agreed Medical Evaluator (AME) who had the simple vision of providing the claims community with credible, well-reasoned medical evaluations. Dr. McAllister chose the field of medicine because he was passionate about helping people. His approach to medical-legal evaluations was the same: he believed that fair, concise, thoughtful reporting helped all parties concerned towards a common goal of resolution.


Today, more than 25 years later, and with more than 36 physicians and 75 locations throughout California, that same spirit of helping others guides everything we do at Arrowhead Evaluation Services, Inc.


We are not in business to merely push paper. Our staff, from the mailing clerk to the CEO, are here to provide a service specifically tailored to the medical and disability claims industry. Our physicians are well respected in their specialties as well as their communities and their reputations are critical to them and AES. At AES, we focus on physician training. Our doctor associates regularly attend the latest seminars to keep well ahead of the learning curve, to avoid having to be “taught” by legal deposition.

We regularly provide feedback to our physicians to fine-tune their reports, in pursuit of the highest standard.
