About Us

What is a medical group?

Anyone who has HMO coverage through their health plan needs to choose a medical group. Your medical group is the connection between your health plan and you. As a member of our medical group, you have access to our network of primary care physicians, specialists, hospitals, urgent care centers, and labs. We also help organize and coordinate all of your care, and provide valuable health programs and services.

Our purpose: To better every life we touch through the way we care.

ADOC Medical Group is an affiliate of Heritage Provider Network (HPN), which has provided affordable and quality healthcare through its network of medical groups for more than 30 years.

HPN founder Richard Merkin, M.D., President and CEO, is the inspiration behind his organization. As a healthcare visionary, he is focused on change and innovation – and this consistent growth is a testament to our quality as we meet the needs of our members throughout Southern California.

High quality standards

We actively work to exceed quality standards. Our medical group has received an elite five-star rating in Standards of Excellence™ from America’s Physician Groups. This rating is the result of a comprehensive, annual survey based on criteria such as proactive care management, accountability, transparency, and best-in-class, patient-focused care.

Complete care

We understand that quality healthcare is about more than seeing your doctor when you’re sick. We offer our members care resources that extend beyond the doctor’s office, like exercise programs for all ages, healthy shopping and cooking classes, and chronic condition management programs. Members who have serious health issues or chronic conditions receive extra support custom tailored to their needs.

Understanding your family

We know that everyone should have a healthcare provider who understands their needs, culture, and speaks their language, and we are proud to offer our members quality care from a diverse network of doctors. Plus, we contract with best-in-class hospitals and other healthcare facilities, enabling our members to have confidence that their families are receiving outstanding healthcare.
