Public Health Job Opportunities: Your Complete Guide to a Rewarding Career in 2025
28 Apr, 2023
When most people think about healthcare careers, physicians and registered nurses come to mind first. But the truth is, allied health specialties represent the largest and fastest-growing segment of the healthcare workforce — and they're absolutely essential to patient care. I've spent years helping healthcare professionals find their ideal roles, and I can tell you with confidence that allied health careers offer some of the most diverse, rewarding, and in-demand opportunities available today.
At healthcareers.app, we connect thousands of job seekers with positions across every corner of healthcare. Whether you're a recent graduate exploring your first career, a seasoned professional considering a pivot, or someone curious about the difference between dietitian types and what an assistant nurse salary looks like, this guide is designed to give you a comprehensive, honest look at what's out there — and how to get started.
Allied health is an umbrella term that encompasses a wide range of healthcare professionals who are not physicians, nurses, dentists, or pharmacists. These professionals work in diagnostic, technical, therapeutic, and direct patient care roles across hospitals, clinics, rehabilitation centers, schools, and community health organizations.
According to the Association of Schools Advancing Health Professions, there are more than 80 distinct allied health professions. That's an incredible range of career paths, each with its own educational requirements, certification processes, and salary expectations. Some of the most well-known allied health specialties include:
What I love about allied health is the sheer diversity. Whether you're drawn to working directly with patients, operating advanced diagnostic equipment, or supporting healthcare from behind the scenes, there's a specialty that fits your strengths and interests.
Let's take a deeper dive into some of the most popular and promising allied health specialties in 2025. I'll break down what each role involves, what you can expect to earn, and what the job market looks like.
Physical therapists (PTs) help patients recover from injuries, surgeries, and chronic conditions by designing individualized treatment plans that improve mobility and reduce pain. Physical therapy assistants (PTAs) work under the supervision of PTs to carry out these treatment plans.
According to the Bureau of Labor Statistics (bls.gov), physical therapists earned a median annual salary of approximately $99,710 in 2023, and employment is projected to grow 15% from 2022 to 2032 — much faster than the average for all occupations. PTAs earned a median of around $62,770, making this an excellent entry point into rehabilitation care.
Respiratory therapists are critical care specialists who treat patients with breathing difficulties, from premature infants with underdeveloped lungs to elderly patients with chronic obstructive pulmonary disease (COPD). The Bureau of Labor Statistics reports a median salary of approximately $77,960 for respiratory therapists, with 13% projected job growth through 2032.
If you prefer working behind the scenes, medical laboratory technologists and technicians analyze blood, tissue, and other body fluids to help diagnose diseases. These professionals are essential to accurate diagnosis, yet they often don't get the recognition they deserve. Median salaries hover around $60,780 for technicians and higher for technologists with advanced credentials.
From X-rays and CT scans to MRIs and mammography, radiologic technologists operate the imaging equipment that physicians rely on for diagnosis. Specialization opportunities abound in this field — you can advance into sonography, nuclear medicine, or radiation therapy, each with its own salary premium and career trajectory.
Surgical technologists, sometimes called operating room technicians, assist during surgeries by preparing operating rooms, arranging equipment, and helping doctors during procedures. It's a fast-paced, high-stakes role that appeals to professionals who thrive under pressure. The median salary is approximately $60,610, according to the Bureau of Labor Statistics.
One of the most frequently asked questions I see from candidates on our platform involves the different dietitian types and how to choose between them. Nutrition is a booming field, and there's more variety here than most people realize.
Clinical dietitians work in hospitals, long-term care facilities, and outpatient clinics. They assess patients' nutritional needs, develop meal plans to support recovery or manage chronic conditions like diabetes and heart disease, and collaborate closely with physicians and nurses. This is the most common type of registered dietitian.
These dietitians work in public health settings, government agencies, and nonprofit organizations. They design nutrition education programs, work on food security initiatives, and develop policies to improve population-level health outcomes. If you're passionate about health equity and prevention, this path is deeply meaningful.
Renal dietitians specialize in working with patients who have kidney disease. Managing fluid, electrolyte, and nutrient intake is critical for these patients, and renal dietitians play a life-saving role in their care teams.
Pediatric dietitians focus on the nutritional needs of infants, children, and adolescents. They address everything from failure to thrive in newborns to eating disorders in teenagers, often working in children's hospitals or specialty clinics.
Sports dietitians work with athletes and fitness-focused individuals to optimize performance through nutrition. They may be employed by professional sports teams, universities, or private practice. This is one of the fastest-growing dietitian types, fueled by increased public interest in fitness and wellness.
According to the Bureau of Labor Statistics, dietitians and nutritionists earned a median annual salary of approximately $69,680 in 2023, with a projected job growth rate of 7% through 2032. Specialization and advanced certifications can push earnings significantly higher.
I frequently get questions about the assistant nurse salary, and I want to give you an honest, nuanced answer because the numbers vary significantly based on location, setting, and experience.
Certified Nursing Assistants (CNAs) are among the most in-demand allied health professionals in the country. They provide essential hands-on care to patients — helping with bathing, dressing, feeding, and mobility — and they serve as the eyes and ears of the nursing staff in hospitals, nursing homes, and assisted living facilities.
According to the Bureau of Labor Statistics, nursing assistants earned a median annual salary of approximately $38,200 in 2023. However, this figure doesn't tell the full story. Here's how the numbers break down by setting:
Several factors can significantly impact what you earn as a nursing assistant:
I always tell candidates on healthcareers.app that while the assistant nurse salary may start modestly, the CNA role is one of the best stepping stones in healthcare. Many registered nurses, nurse practitioners, and even physicians started their careers as CNAs, gaining invaluable patient care experience along the way.
With more than 80 allied health specialties to consider, choosing the right one can feel overwhelming. Here's the framework I recommend to candidates who come to us unsure of where to start:
Ask yourself these questions: Do you want direct patient contact, or do you prefer working with technology and data? Are you comfortable in high-pressure environments like operating rooms and ICUs, or do you prefer outpatient or community settings? Do you want a career that requires a two-year degree, or are you willing to invest in a four-year or graduate program?
Allied health specialties span a wide range of educational requirements. Some roles, like CNA, require only a few weeks of training and state certification. Others, like physical therapy or speech-language pathology, require a master's or doctoral degree. Understanding the time and financial investment upfront will help you make an informed decision.
One of the most practical things you can do is search for open positions on platforms like healthcareers.app to see which allied health specialties have the most openings in your geographic area. A role that's in high demand locally means more negotiating power, better benefits, and greater job security.
Think about where you want to be in 5, 10, or 20 years. Many allied health specialties offer clear advancement paths — from technician to technologist to supervisor to department director. Others, like dietetics, offer the opportunity to specialize in niche areas that command higher salaries and greater autonomy.
The outlook for allied health careers has never been brighter. The Bureau of Labor Statistics projects that healthcare occupations overall will grow by approximately 13% from 2022 to 2032, adding about 1.8 million new jobs. Several trends are driving this growth:
We built healthcareers.app because we saw a gap in how allied health professionals find and connect with the right opportunities. Our platform is designed specifically for healthcare workers, which means every listing you see is relevant, and every employer is actively seeking the skills you bring to the table.
Among the highest-paying allied health specialties are radiation therapists, physical therapists, occupational therapists, and speech-language pathologists, all of which have median annual salaries ranging from $90,000 to over $100,000 according to the Bureau of Labor Statistics. Specialized roles like physician assistants, which some classifications include under allied health, can earn even more.
It depends entirely on the specialty. Certified Nursing Assistant programs can be completed in as little as 4–12 weeks. Associate degree programs for roles like respiratory therapy or radiologic technology take about two years. Doctoral-level roles like physical therapy require 6–7 years of post-secondary education. The diversity of entry points is one of the greatest strengths of allied health careers.
The assistant nurse salary varies significantly by location and setting. While the national median of approximately $38,200 may be challenging in high-cost-of-living areas, many CNAs supplement their income through shift differentials, overtime, and per diem work. Additionally, many employers now offer tuition assistance programs that allow CNAs to advance into higher-paying nursing roles while working.
Clinical dietitians remain the most in-demand, particularly in hospital and long-term care settings. However, renal dietitians and pediatric dietitians are experiencing growing demand due to rising rates of kidney disease and childhood nutritional challenges. Sports and performance dietitians are also seeing increased opportunities as wellness and preventive care gain mainstream attention.
Absolutely. Many skills in allied health are transferable — patient communication, clinical reasoning, teamwork, and technical proficiency apply across specialties. Transitioning typically requires additional education or certification, but your foundational healthcare experience gives you a significant advantage. I've seen countless professionals on our platform successfully pivot between allied health roles throughout their careers.
Allied health specialties offer something for virtually everyone — whether you're drawn to the technical precision of medical imaging, the compassionate care of nursing assistance, or the science-backed problem solving of clinical nutrition. The demand is strong, the career paths are diverse, and the impact you can make on patients' lives is profound.
I encourage you to explore the full range of opportunities available to you. Research the educational requirements, understand the salary landscape, and most importantly, find a role that aligns with your skills and passions.
