Public Health Professions You Haven't Considered: From Osteopathic Medicine to Ophthalmology Tech
29 Aug, 2026
If you've been browsing healthcare job listings, researching medical schools, or simply trying to understand the credentials after a physician's name, you've likely encountered the term medical D.O. — and wondered how it differs from an M.D. The distinction matters more than most people realize, not because one degree is "better" than the other, but because understanding the D.O. pathway can unlock career opportunities, mentorship networks, and practice philosophies that align more closely with your goals.
I've spent years helping healthcare professionals at every stage navigate career decisions, and one of the most common questions I hear from pre-med students, career changers, and even practicing clinicians is: "Does it matter whether I'm a D.O. or an M.D.?" The short answer is that both are fully licensed physicians. The longer answer — the one that actually helps you make decisions — is what this post is about.
A D.O. — Doctor of Osteopathic Medicine — is a fully licensed physician who has completed four years of osteopathic medical school followed by residency training. D.O. physicians can prescribe medication, perform surgery, specialize in any field of medicine, and practice in all 50 states and internationally. They take their own board exams (COMLEX-USA), though many also sit for the USMLE exams that M.D. graduates take.
The key philosophical difference lies in osteopathic medicine's foundational emphasis on the musculoskeletal system, whole-person care, and osteopathic manipulative treatment (OMT). In practice, this means D.O. students receive additional training in hands-on diagnostic and treatment techniques that complement standard medical education.
Osteopathic medicine is one of the fastest-growing segments of U.S. medical education. According to the American Association of Colleges of Osteopathic Medicine (AACOM), roughly 25 percent of all medical students in the United States now attend osteopathic medical schools. There are more than 40 accredited colleges of osteopathic medicine across the country, and enrollment has grown substantially over the past two decades. For job seekers, this means you'll increasingly encounter D.O. colleagues, supervisors, and collaborators in virtually every healthcare setting.
Historically, osteopathic medicine has been closely associated with primary care — family medicine, internal medicine, and pediatrics. And it's true that a higher percentage of D.O. graduates enter primary care compared to M.D. graduates. But that landscape is evolving quickly. Today, D.O. physicians practice in every specialty, from orthopedic surgery and cardiology to psychiatry and emergency medicine.
Since the 2020 merger of the osteopathic and allopathic graduate medical education (GME) accreditation systems under a single ACGME framework, D.O. and M.D. graduates now compete for the same residency positions. This single accreditation system has effectively leveled the playing field, making the D.O. credential more widely recognized and accepted across all specialties.
D.O. physicians are disproportionately represented in underserved and rural communities — a fact that reflects both the osteopathic mission and the geographic distribution of many osteopathic medical schools. If you're a job seeker exploring opportunities in community health centers, rural hospitals, or federally qualified health centers, you'll find that D.O. physicians often serve as anchor providers in these settings.
That said, D.O. physicians also hold leadership positions at major academic medical centers, research institutions, and large health systems. The credential does not limit where you can practice.
One area where the D.O. philosophy of holistic, patient-centered care intersects beautifully with another healthcare role is in geriatric medicine. A gerontology nurse — whether working as a geriatric nurse practitioner, a certified gerontological nurse, or a clinical nurse specialist in aging — frequently collaborates with D.O. physicians who specialize in geriatrics or family medicine with a geriatric focus.
The osteopathic emphasis on the whole person — body, mind, and spirit — aligns naturally with the gerontology nurse's approach to caring for older adults with complex, interconnected health needs. If you're a gerontology nurse exploring your next career move, understanding the D.O. credential can help you identify practice environments where your philosophy of care is shared by the physicians on the team. On healthcareers.app, we regularly feature positions where D.O.-led practices specifically seek gerontology nurses who value that interdisciplinary, whole-person model.
Here's a connection that might surprise you: medical illustrator schools and osteopathic medical education share an unusually deep relationship with anatomical knowledge. Osteopathic medical students receive extensive training in anatomy, often with more hands-on cadaver lab hours than their M.D. counterparts, because OMT requires an intimate understanding of musculoskeletal structure.
Medical illustrators — professionals who create detailed visual representations of anatomical structures, surgical procedures, and medical concepts — rely on the same depth of anatomical expertise. Several medical illustrator schools, including well-known programs at institutions like Johns Hopkins University, Augusta University, and the University of Illinois at Chicago, require applicants to have strong foundations in both science and art. Some medical illustration graduates go on to work closely with D.O. programs, creating educational materials that support osteopathic manipulative technique training.
If you're considering a career in medical illustration, understanding the D.O. world can open doors to niche opportunities in osteopathic educational publishing, continuing medical education content, and anatomical visualization for OMT research.
Based on what I've seen from thousands of healthcare job seekers using our platform, here are practical tips specifically for D.O. physicians:
If you're a hiring manager or practice administrator, here's my advice: treat D.O. and M.D. credentials as equivalent in your job postings. Both represent fully licensed physicians. Specifying "M.D. only" in a job listing not only narrows your talent pool unnecessarily — it may also signal a bias that deters other strong candidates from applying. In a market where physician shortages are a real and growing concern, you can't afford to exclude 25 percent of new medical graduates.
Let me address some persistent myths I encounter regularly:
The trajectory is clear: osteopathic medicine's role in the U.S. healthcare system is expanding. New osteopathic medical schools continue to open, particularly in states with physician shortages. The single GME accreditation system has removed a major structural barrier. And the emphasis on primary care, preventive medicine, and whole-person treatment aligns with broader shifts in healthcare delivery toward value-based care models.
For healthcare job seekers of all kinds — whether you're a medical student choosing between D.O. and M.D. programs, a gerontology nurse looking for the right practice environment, or someone exploring non-clinical healthcare careers like medical illustration — understanding the D.O. landscape helps you make more informed decisions about where you fit in this changing industry.
A D.O. (Doctor of Osteopathic Medicine) and an M.D. (Doctor of Medicine) are both fully licensed physicians who can diagnose, treat, prescribe medication, and perform surgery. The primary difference is that D.O. training includes additional coursework in osteopathic manipulative treatment and emphasizes a whole-body approach to medicine. Since the GME merger, both compete for the same residency positions and are recognized equally by hospitals and licensing boards.
Absolutely. D.O. physicians practice in every medical specialty, including orthopedic surgery, neurosurgery, cardiology, dermatology, and more. The single accreditation system for residencies means D.O. graduates apply to the same programs as M.D. graduates and are evaluated on the same criteria.
A gerontology nurse often finds strong alignment with D.O. physicians because of the shared emphasis on holistic, patient-centered care. In geriatric settings, where patients typically have multiple interacting conditions, the D.O. approach of considering the whole person — including musculoskeletal health, mental well-being, and social factors — complements the gerontology nurse's expertise in comprehensive aging care.
Medical illustrator schools emphasize deep anatomical knowledge, which overlaps significantly with the anatomy-intensive training in osteopathic medical programs. Medical illustrators may find specialized career opportunities creating educational content for D.O. programs, particularly materials that visualize osteopathic manipulative techniques and musculoskeletal anatomy.
Yes. Physician demand remains strong across the board, and D.O. physicians are especially well-positioned for primary care roles, rural and underserved community positions, and specialties facing workforce shortages. The Bureau of Labor Statistics projects continued growth in physician employment, and health systems increasingly recruit D.O. physicians to meet patient care needs.
The medical D.O. credential represents a rigorous, fully equivalent pathway to becoming a physician — one that happens to carry a distinctive philosophy about how the body works and how patients should be cared for. Whether you're considering osteopathic medical school, searching for physician jobs, collaborating with D.O. physicians as a gerontology nurse, or creating anatomical content after attending one of the top medical illustrator schools, understanding what the D.O. means — and what it doesn't — puts you in a stronger position to navigate your healthcare career.
