Detailed Guide for

Physician Assistants in Sonoma County

May also be called: Physician's Assistants; Physician Assistant Certified Assistants

Specialties within this occupation include: Family Practice Physician Assistants; Orthopedic Physician Assistants; Pediatric Physician Assistants; Surgical Physician Assistants

What Would I Do?

Physician Assistants (PAs) practice medicine under the supervision of physicians. They are formally trained to provide diagnostic, therapeutic, and preventive health care services. Specific duties of Physician Assistants are determined by their supervising physicians and by State law. Working as members of a health care team, they take medical histories, examine and treat patients, order and interpret laboratory tests and X rays, and make diagnoses. They also treat minor injuries by suturing, splinting, and casting. The PAs record patients' progress, instruct and counsel patients, and order or carry out therapy. They may administer immunizations and injections, perform minor surgery, and assist in surgery. If they meet the legal requirements, Physician Assistants may prescribe some medications.

In some establishments, a PA has managerial duties, such as ordering medical supplies or equipment and supervising technicians and assistants. Physician Assistants may be the principal care providers in rural or inner city clinics where a physician is present for only one or two days each week. In such cases, the PA confers with the supervising physician and other medical professionals as needed and as required by law.

Many PAs work in primary care specialties, such as general internal medicine, pediatrics, and family medicine. Other specialty areas include general and thoracic surgery, emergency medicine, orthopedics, and geriatrics. The PAs specializing in surgery provide preoperative and postoperative care and may work as first or second assistants during major surgery.

Physician Assistants use medical devices such as microscopes, catheters, glucose monitors, hypodermic needles, lancets, and tourniquets. They also operate software such as medical, storage media loading, spreadsheet, word processing, and Web browser.

Working Conditions

Usually PAs work in comfortable, well-lit healthcare facilities. At times the job requires a considerable amount of walking. On the other hand, those in surgery often stand for long periods. The PAs may travel to patients' homes or visit them in hospitals and nursing care facilities, then report back to the physician.

Schedules vary depending on where the PA works and the hours of the supervising physician. The workweek of hospital-based PAs may include 12-hour shifts, weekends, nights, or early morning hospital rounds to visit patients. These workers may also be on call. However, PAs in clinics usually work a traditional workweek. Some PAs may hold two or more jobs.

Physician Assistants may become members of a labor union, such as the United Nurses Associations of California/Union of Health Care Professionals or American Academy of Physician Assistants.

Will This Job Fit Me?

The job of Physician Assistant may appeal to those who enjoy activities that involve working with ideas that require an extensive amount of thinking, searching for facts, and figuring out problems. Results-oriented individuals who are independent workers and like to make their own decisions should enjoy this type of job.

What Wages and Benefits Can I Expect?

Income varies by specialty, practice setting, geographical location, and years of experience.


The median wage in 2022 for Physician Assistants in California is $135,290 annually, or $65.04 hourly. The median wage for Physician Assistants in Sonoma County is greater than $145,600 annually. The median is the point at which half of the workers earn more and half earn less.

Benefits generally include medical, dental, life, and vision insurance as well as vacation, sick leave, and retirement plans. Some employers pay for their employees’ liability insurance, Drug Enforcement Administration's registration fees, State licensing fees, credentialing fees, and continuing education expenses.

What is the Job Outlook?

Physicians and institutions are expected to employ more PAs to provide primary care and to assist with medical and surgical procedures because PAs are cost-effective and productive members of the health care team. Physician Assistants relieve physicians of routine duties and procedures. The use of technology, such as the telephone or Internet, to facilitate interactive consultations between physicians and Physician Assistants will also expand the use of Physician Assistants.

Besides working in traditional office-based settings, PAs should find a growing number of jobs in institutional settings such as hospitals, academic medical centers, public clinics, and prisons. Physician Assistants also may be needed to augment medical staffing in teaching hospitals where the number of hours physician residents are permitted to work is reduced, encouraging hospitals to use PAs to supply some physician resident services.

Job opportunities for PAs should be good, particularly in certain rural and inner-city clinics because these settings have difficulty attracting physicians.

How Do I Qualify?

Education, Training, and Other Requirements

California requires completion of an American Academy of Physician Assistants' accredited, formal education program and passing of a national exam to obtain a license. Physician assistant education programs last at least two years and are full time. Most programs are in schools of allied health, academic health centers, medical schools, and four-year colleges. Other programs are offered in community colleges, the military, and hospitals. The accredited programs have clinical teaching affiliations with medical schools. Several of these programs offer the option of a master’s degree. The rest offer either a bachelor’s degree or an associate degree.

Admission requirements vary, but many programs require two years of college and some work experience in the health care field. Many PAs have prior experience as registered nurses, while others come from varied backgrounds. These include military corpsman or medics and allied health occupations, such as respiratory therapists, physical therapists, emergency medical technicians, and paramedics. Many applicants to PA educational programs already have an associate or bachelor’s degree.

Physician Assistants must have a desire to serve patients and be self-motivated. They also must have a good bedside manner, emotional stability, and the ability to make decisions in emergencies.


Before working as a PA, students must complete supervised clinical training in several areas including family medicine, internal medicine, surgery, prenatal care, gynecology, geriatrics, emergency medicine, psychiatry, and pediatrics.

Early Career Planning

Students interested in becoming a Physician Assistant should take courses in biology, English, chemistry, mathematics, psychology, health, and the social sciences.

Work Study Programs

Some Regional Occupational Programs (ROP) offer introductory courses in the health care field, such as Medical Terminology that could be helpful to explore and prepare for medical careers.  To find an ROP program near you, go to the California Association of Regional Occupational Centers and Programs Web site.

Continuing Education

Physician Assistants must be willing to study throughout their career to keep up with medical advances. They are also responsible for keeping current with the regulations and laws pertaining to their career. To remain certified by the National Commission on Certification of Physician Assistants (NCCPA), PAs must complete 100 hours of continuing medical education every 2 years.

Licensing and Certification

In order for Physician Assistants to practice in California, they must obtain a license from the Physician Assistant Committee of the Medical Board of California. Applicants must have graduated from a training program accredited by the Accreditation Review Commission on Education for the Physician Assistant, pass the NCCPA exam, pay appropriate fees, and obtain a Live Scan fingerprinting and background clearance. The license is renewable every two years.

The PAs who are authorized by their supervising physician to dispense drug orders for controlled substances must register with the DEA to obtain a federal DEA number. Contact the agency that issues the license for additional information. Click on the license title below for details.

The NCCPA offers certification to graduates of accredited physician assistant education programs. Only those successfully completing the examination may use the credential “Physician Assistant-Certified.” To maintain certification, holders must meet continuing medical education requirements and pass a recertification exam every six years or complete an alternative program combining learning experiences and a take-home examination. For more information, go to the U.S. Department of Labor's Career InfoNet Web site and scroll down to "Career Tools." Click on "Certification Finder" and follow the instructions to locate certification programs.
