Ventura County Hematology Oncology Specialists Medical Group was originally  founded in 1971 with the goal of providing the highest quality of care for patients with cancer and blood disorders with office locations in the coastal cities of Ventura, Oxnard and Camarillo. Physicians are board certified in Internal Medicine, Hematology and Medical Oncology.  They are also active participants and leaders  of the Cancer Center of Ventura County located in Oxnard and the Coastal Communities Cancer Center in Ventura. 

The physicians regularly participate in multidisciplinary tumor boards and engage in weekly internal case meetings in order to provide their patients with the best treatment options available.

As investigators for clinical trials listed in the National Institutes of Health's (NIH) National Cancer Institute (NCI) database, physicians at Ventura County Hematology Oncology Specialists are able to offer access to the newest innovations in cancer care to provide the best treatment options to their patients here in Ventura County.  

The group is a proud participant of the Oncology Care Model (OCM), a Medicare and Medicaid Innovation project which aims to provide patients with excellent quality and highly coordinated oncology care at the same or lower cost to Medicare.


Our team of medical, clinical and support staff is committed to improving the way medical care is delivered today and tomorrow. Physicians and staff work together to ensure patients receive cutting-edge cancer and blood disorder therapies in an environment that reflects compassion and commitment to life.
