11 Apr, 2026
If you're exploring a career in healthcare but aren't sure whether medical school or nursing school is right for you, I have great news: there's an entire universe of rewarding, in-demand careers waiting for you. A comprehensive list of allied health professions includes more than 80 distinct disciplines — from respiratory therapists and diagnostic sonographers to exercise physiologists and nurse researchers. These professionals make up roughly 60 percent of the total healthcare workforce, and I've spent years helping job seekers on healthcareers.app discover just how many doors these careers can open.
In this guide, I'll walk you through the major allied health professions, highlight specific roles like exercise physiologists and nurse researchers, break down salary expectations, and give you a clear roadmap for launching your career. Whether you're a recent graduate, a career changer, or someone looking to advance within healthcare, this is your one-stop resource.
Allied health professions encompass virtually every healthcare discipline outside of medicine, nursing, dentistry, and pharmacy. According to the Association of Schools Advancing Health Professions (ASAHP), allied health professionals are involved in the delivery of health services related to the identification, evaluation, and prevention of diseases and disorders; dietary and nutrition services; rehabilitation; and health systems management. That's an incredibly broad scope, and it's exactly why this sector offers so much opportunity.
What unites all allied health workers is their focus on patient care, diagnostic services, therapeutic interventions, or health information management — typically requiring specialized education ranging from a certificate to a doctoral degree. The Bureau of Labor Statistics projects that healthcare occupations overall will grow by about 13 percent from 2021 to 2031, much faster than the average for all occupations, and allied health roles are a major driver of that growth.
Below, I've organized the most prominent allied health professions into categories. This list of allied health professions is not exhaustive — new specializations emerge every year — but it covers the roles we see most frequently on healthcareers.app and the ones job seekers ask about most often.
This is just a snapshot. Other roles on our list of allied health professions include genetic counselors, prosthetists and orthotists, perfusionists, surgical technologists, medical assistants, and many more. We regularly update job listings for all of these roles on healthcareers.app.
One role I'm frequently asked about is the exercise physiologist, and I think it deserves a thorough description of exercise physiologist responsibilities because it's one of the most misunderstood allied health careers.
An exercise physiologist develops individualized fitness and exercise programs to help patients recover from chronic diseases and improve cardiovascular function, body composition, and flexibility. They work in hospitals, rehabilitation clinics, cardiac rehabilitation centers, sports medicine facilities, and wellness programs. On any given day, an exercise physiologist might perform stress tests, analyze a patient's medical history, design a graduated exercise protocol for a cardiac rehab patient, or educate someone with diabetes about the role of physical activity in managing blood sugar.
According to the Bureau of Labor Statistics, exercise physiologists earned a median annual wage of approximately $51,350 as of May 2023. Most positions require at least a bachelor's degree in exercise physiology, exercise science, or kinesiology. Many employers prefer candidates who hold certification through the American College of Sports Medicine (ACSM) as a Certified Exercise Physiologist.
What I love about this career is the blend of science and human connection. You're applying deep knowledge of physiology, biomechanics, and nutrition while building genuine relationships with patients who are often at vulnerable points in their lives. If you're passionate about fitness and want to make a clinical impact, this could be the perfect fit.
Another question I encounter regularly on healthcareers.app is: how much do nurse researchers make? It's a fair question, especially because this role sits at the intersection of clinical nursing and academic research, which can make salary data harder to pin down.
Nurse researchers design and conduct studies that improve patient care, evaluate treatment effectiveness, and shape healthcare policy. They typically hold a Master of Science in Nursing (MSN) or a Doctor of Nursing Practice (DNP) or PhD in Nursing. They work in universities, hospitals, government agencies like the National Institutes of Health (NIH), pharmaceutical companies, and research institutes.
While the Bureau of Labor Statistics doesn't have a separate category exclusively for nurse researchers, the data available through related classifications and industry salary surveys gives us a clear picture. According to salary data aggregated from healthcare institutions and reported by organizations like the American Association of Colleges of Nursing, nurse researchers typically earn between $75,000 and $120,000 per year, depending on education level, geographic location, and employer type. Those working in academic medical centers or for federal agencies like the NIH often command salaries at the higher end of that range, with senior researchers and principal investigators earning well over $120,000.
I want to emphasize that the earning potential for nurse researchers continues to grow as the healthcare industry increasingly relies on evidence-based practice. If you're a nurse with a passion for inquiry and a desire to influence care on a systemic level, this career path offers both intellectual fulfillment and competitive compensation.
With so many options on the list of allied health professions, choosing the right one can feel overwhelming. Here's the framework I recommend to job seekers on our platform:
Do you prefer hands-on patient care, or are you more drawn to behind-the-scenes work like laboratory analysis or health informatics? Are you energized by emergency situations, or do you thrive in slow, methodical research environments? Being honest about your preferences will immediately narrow the field.
Some allied health careers require only a certificate or associate degree and can get you working within one to two years. Examples include phlebotomists, medical assistants, and dental assistants. Others, like physical therapists and speech-language pathologists, require doctoral or master's degrees. Map out the time and financial investment against your personal circumstances.
I always encourage candidates to check the Bureau of Labor Statistics Occupational Outlook Handbook for projected growth rates. Roles like respiratory therapists, diagnostic medical sonographers, and physical therapy assistants are projected to grow significantly faster than average through 2031. Choosing a high-demand profession gives you more leverage in salary negotiations and more geographic flexibility.
Salary varies enormously across allied health professions. A phlebotomist might start around $38,000, while a physical therapist can earn upward of $95,000. Use our salary resources on healthcareers.app and cross-reference them with BLS data to set realistic expectations.
Before committing to a program, try to shadow or volunteer in a clinical setting related to your target profession. Nothing replaces the experience of seeing a role in action. Many of the job seekers I've helped on our platform say that a single day of shadowing confirmed — or changed — their career direction entirely.
The healthcare landscape is evolving rapidly, and allied health professions are evolving with it. Telehealth has expanded the reach of roles like speech-language pathology, dietetics, and mental health counseling. Advances in artificial intelligence are reshaping diagnostic imaging and health informatics. An aging population is driving unprecedented demand for rehabilitation therapists, respiratory therapists, and home health professionals.
According to the Centers for Disease Control and Prevention (CDC), chronic diseases such as heart disease, cancer, and diabetes are responsible for 7 out of 10 deaths in the United States each year and account for the majority of healthcare spending. This reality means that allied health professionals — especially those in prevention, rehabilitation, and chronic disease management — will only become more essential in the years ahead.
We built healthcareers.app because we believe every allied health professional deserves access to the best opportunities available. Whether you're just starting out or looking to advance, our platform is designed to connect you with employers who value your expertise.
Among allied health roles, radiation therapists, physical therapists, and speech-language pathologists tend to be among the highest earners, with median salaries ranging from $80,000 to over $95,000 per year according to the Bureau of Labor Statistics. Roles that require advanced degrees and specialized certifications generally command the highest salaries.
No. While some allied health careers require a master's or doctoral degree (such as physical therapy or audiology), many entry-level roles — including medical assisting, phlebotomy, and dental assisting — require only a certificate or associate degree. These can often be completed in two years or less.
The Bureau of Labor Statistics projects that employment for exercise physiologists will grow by about 13 percent from 2022 to 2032, which is much faster than the average for all occupations. Growing awareness of the role of physical activity in managing chronic diseases is a key driver of this demand. The description of exercise physiologist responsibilities increasingly includes work in corporate wellness programs and telehealth settings.
Nurse researchers generally earn between $75,000 and $120,000 per year, which is comparable to or higher than many clinical nursing roles, particularly when the researcher holds a doctoral degree. The question of how much do nurse researchers make depends heavily on the employer, geographic location, and years of experience. Those at major research universities or the NIH tend to earn at the top of the range.
I recommend starting with healthcareers.app, where we list allied health positions across all specialties and geographic areas. You can filter by profession, location, salary range, and experience level to find opportunities that match your qualifications and goals.
The list of allied health professions is long, diverse, and filled with opportunity.

I've watched thousands of job seekers on healthcareers.app transform their careers by discovering the allied health profession that aligns with their skills, passions, and lifestyle goals. My hope is that this guide gives you the knowledge and confidence to take that next step — whatever it may be. Your future in healthcare is waiting, and we're here to help you find it.
