To find the best of what’s possible in medicine

About Us

More than 17 years ago, Private Health Management’s (PHM) founders recognized that closing the many gaps in a patient’s typical healthcare experience leads to significantly better health outcomes for serious or complex illnesses.  PHM was built on the vision of bringing this life-enhancing support to as many people as possible.

PHM is a clinically sophisticated complex care management company, specializing in assisting clients to obtain the best care and outcomes when facing serious and complex medical conditions. Individuals and businesses that make their employees’ health a priority rely on PHM to achieve the best of what’s possible in medicine.



We believe everyone should benefit from the latest science-backed insights, have access to the best diagnostics, specialists and treatments, and receive independent guidance to make informed health decisions with confidence.
