Odontologists: The Dental Detectives Most People Don't Know Exist
18 Sep, 2026
If you've ever asked "what is allied health professional?" and gotten a vague answer involving physical therapists and maybe X-ray technicians, you're not alone. I've spent years building healthcareers.app and talking with thousands of job seekers, and I can tell you that allied health is one of the most misunderstood — and most opportunity-rich — corners of healthcare. Most people default to thinking of doctors and nurses when they picture healthcare careers. But allied health professionals make up an estimated 60 percent of the total healthcare workforce in the United States. They're the diagnostic backbone, the rehabilitation engine, and increasingly, the innovation layer of modern medicine.
The problem? The term "allied health" is so broad that it often gets reduced to a handful of familiar roles. In this post, I want to go beyond the usual suspects and spotlight 17 allied health roles that most people have never considered — including a few that sound more like they belong in a crime drama or a nature documentary than a hospital.
The Association of Schools Advancing Health Professions defines allied health professionals as those who are involved in the delivery of health services but are distinct from physicians, nurses, dentists, and pharmacists. That definition technically covers more than 80 distinct occupations. The Bureau of Labor Statistics groups many of them under "healthcare practitioners and technical occupations" or "healthcare support occupations," and the agency consistently projects strong growth across allied health fields through the end of this decade and beyond.
But here's the thing: that official definition doesn't capture the sheer weirdness and diversity of what allied health professionals actually do. Some work in gleaming hospital labs. Others work outdoors at crime scenes. A few work with animals — yes, really. Let me show you what I mean.
When people hear "forensics entomology," they usually think of a fictional TV lab. But forensic entomologists are real allied health professionals who study insect activity on human remains to help determine time of death, location of death, and whether a body has been moved. They work with medical examiners, law enforcement, and public health agencies. While this role typically requires graduate-level education in entomology, it's increasingly recognized as part of the forensic health sciences ecosystem. If CSI fascinated you but you wanted something rooted in actual biological science, forensics entomology is a legitimate — if highly specialized — career path.
You might have heard someone jokingly called "the cat whisperer" at a veterinary clinic. But animal-assisted therapy is a structured, evidence-based allied health practice. Specialists in this field use trained animals — cats, dogs, horses, even rabbits — as part of therapeutic interventions for patients dealing with PTSD, autism spectrum disorder, chronic pain, and depression. These professionals typically hold credentials in occupational therapy, recreational therapy, or counseling, with additional certification in animal-assisted interventions. Being "the cat whisperer" in a clinical rehabilitation setting is, as it turns out, a real job with real outcomes data behind it.
These specialists design, fabricate, and fit orthopedic braces (orthotics) and artificial limbs (prosthetics). It's equal parts engineering, anatomy, and patient counseling. The field is growing rapidly as 3D printing and advanced materials transform what's possible.
Dosimetrists work alongside radiation oncologists to calculate the exact radiation dose a cancer patient needs. Too little and the treatment fails; too much and healthy tissue is destroyed. It's precision science with life-or-death stakes, and most people outside oncology have never heard the title.
During open-heart surgery, someone has to operate the heart-lung machine that keeps a patient alive while the surgeon works on the heart. That someone is a perfusionist. They're critical members of the surgical team, and the role typically requires a bachelor's or master's degree from an accredited perfusion program.
Cytotechnologists examine cells under a microscope to detect cancer, infections, and other abnormalities. They're the professionals who screen Pap smears, for example. Their work directly influences diagnosis and treatment decisions, yet the role gets almost zero public visibility.
With the explosion of genomic medicine, genetic counselors have become essential. They help patients understand genetic test results, assess hereditary cancer risk, and navigate the emotional complexity of learning about predispositions to disease. The Bureau of Labor Statistics has projected this field to grow much faster than average.
Not to be confused with physical therapists, kinesiotherapists specialize in therapeutic exercise as a primary treatment modality. They're common in Veterans Affairs medical centers, where they work with veterans recovering from injuries, amputations, and neurological conditions.
Someone has to ensure that the billions of patient records across the healthcare system are accurate, secure, and compliant with regulations like HIPAA. Health information managers are the professionals who do it. With the shift to electronic health records and growing cybersecurity concerns, this role has evolved far beyond filing cabinets.
Recreational therapists use activities like art, music, dance, sports, and community outings as therapeutic interventions for people with disabilities, injuries, or illnesses. It's structured, goal-oriented therapy — not just fun and games — and it's practiced in hospitals, rehabilitation centers, and community mental health settings.
These technologists perform advanced diagnostic tests for ophthalmologists, including visual field testing, optic nerve imaging, and ultrasound of the eye. The role requires deeper clinical knowledge than an ophthalmic technician and often involves managing complex instruments that cost hundreds of thousands of dollars.
Sleep techs monitor patients overnight in sleep labs, recording brain waves, oxygen levels, heart rates, and breathing patterns to help diagnose disorders like sleep apnea and narcolepsy. It's a role made for night owls — literally.
Every surgical instrument that touches a patient must be meticulously cleaned, sterilized, and inspected. Sterile processing technicians are the gatekeepers of surgical safety. It's one of the fastest entry points into allied health, often requiring only a certificate, but the responsibility is enormous.
Rehabilitation engineers apply engineering principles to develop technology that helps people with disabilities. Think custom wheelchair designs, adaptive computer interfaces, and smart prosthetics. It sits at the intersection of biomedical engineering and clinical allied health.
Art therapists hold master's degrees and use creative expression as a clinical intervention for trauma, grief, anxiety, and developmental disorders. They work in psychiatric hospitals, schools, hospices, and private practice. The American Art Therapy Association provides credentialing standards for the profession.
Clinical exercise physiologists develop fitness programs for patients with chronic diseases like diabetes, heart disease, and pulmonary conditions. They perform stress tests, analyze cardiopulmonary data, and work directly with physicians on treatment plans. It's personal training elevated to clinical science.
Surgical first assistants work directly alongside surgeons, handling tissue, providing exposure, controlling bleeding, and suturing. They're not surgeons, but they're deeply involved in the operative process. Many come from surgical technology backgrounds and pursue additional certification.
Despite covering everything from insect analysis in forensics entomology to being the cat whisperer in an animal-assisted therapy session, these 17 roles share several defining characteristics of allied health professions:
I talk to job seekers every day who feel stuck choosing between the obvious options: nursing, medical school, or "something else." If you're drawn to healthcare but none of the traditional paths feel right, here's how I recommend narrowing down your allied health options:
Are you fascinated by technology? Look into roles like perfusion, dosimetry, or rehabilitation engineering. Do you gravitate toward hands-on creative work? Art therapy and orthotics/prosthetics might speak to you. Are you a detail-obsessed problem solver? Cytotechnology and health information management could be your lane. Do you find insects and forensic science captivating? Forensics entomology is a real thing, and it needs people.
Allied health professionals work in radically different settings. Sleep techs work nights. Recreational therapists might work outdoors. Forensic entomologists may work at crime scenes. Sterile processing techs work in the controlled environment of a hospital's central supply department. The setting matters as much as the job description.
Some allied health careers require a two-year associate degree or certificate. Others demand a master's or doctorate. Be honest about your timeline and financial situation. A sterile processing certificate can get you into a hospital in months; becoming a genetic counselor requires a master's degree from an accredited program.
An allied health professional is any healthcare worker who is not a physician, nurse, dentist, or pharmacist but is involved in delivering health services. This includes more than 80 distinct occupations spanning diagnostics, rehabilitation, therapy, technology, health information, and forensic sciences. The term encompasses everyone from physical therapists and radiologic technologists to lesser-known roles like dosimetrists, perfusionists, and forensic entomologists.
Most do, though the specifics vary by role and state. Many allied health occupations require national certification or registration from a professional body, and most states require licensure for clinical roles. For example, respiratory therapists must be licensed in all 50 states, while some health information roles may require only certification. I always recommend checking your state's health professions regulatory board for the most current requirements.
Forensics entomology occupies a unique position. While it's rooted in biological science, it's increasingly recognized within the broader forensic health sciences. Forensic entomologists frequently collaborate with medical examiners and forensic pathologists, placing them adjacent to — and in many organizational structures, within — the allied health umbrella. It's a niche field, but it's a legitimate one.
Roles like perfusionist, radiation therapist, genetic counselor, and orthotist/prosthetist tend to rank among the higher-paying allied health positions, according to data from the Bureau of Labor Statistics. Compensation varies significantly by geography, experience, and work setting. I encourage job seekers to explore current salary data on our platform at healthcareers.app for role-specific insights.
Absolutely. Several allied health careers are accessible with a certificate or associate degree. Sterile processing technicians, polysomnographic technologists, and some health information roles offer entry points that don't require a bachelor's degree. These can also serve as stepping stones — many professionals use an initial allied health role to gain clinical experience before pursuing additional education.
So, what is an allied health professional? The honest answer is that it's almost impossible to summarize in a single sentence, because the field stretches from the cat whisperer guiding a therapy cat through a psychiatric ward to the forensics entomology specialist analyzing larvae at a crime scene — and includes dozens of critical roles in between. What I can tell you is this: allied health is where some of the most fascinating, impactful, and overlooked careers in healthcare live. If you're exploring your options, don't limit yourself to the roles you already know. The ones you've never heard of might be the perfect fit. We built healthcareers.app to help you find exactly those opportunities, and I'd encourage you to browse our allied health listings to see what's out there.
