Doctors and nurses may be the most well-known health care professionals, but there are many other careers in this exciting and growing field.

Although some of these professionals have patient contact, most are the people who keep the organizations running--administrators, managers, and other specialists.

According to the U.S. Department of Labor Bureau of Labor Statistics, health care is one of the largest industries in the country, with about 11.3 million jobs. About 14 percent of all wage and salary jobs created between 1998 and 2008 will be in health services and 12 out of 30 occupations projected to grow the fastest are concentrated in health services.

Factors contributing to this continued growth include the aging population, which will continue to require more services, and the increased use of technology for intensive diagnosis and treatment.

Professionals who support the health and medical industry must be self-directed and able to work independently. They also need tact, good judgment, and effective interpersonal and communication skills to interact with a wide range of medical personnel.

In contrast to doctors and nurses, who provide patient care around the clock, most administrative professionals work a standard daytime schedule. Evening or weekend hours may occasionally be required, but only to address problems, travel, or attend meetings. Working conditions vary by occupation but are generally comfortable.
