Dosimetrist Career Guide: Role, Salary, Education, and How to Get Started
11 Apr, 2026
If you've ever dreamed of diagnosing illnesses, saving lives, or leading a healthcare team, a career as a physician might be the path you've been searching for. I've spent years working with healthcare professionals at every stage of their journey — from pre-med students questioning their first steps to seasoned attending physicians exploring new specialties — and I can tell you that medicine remains one of the most rewarding, challenging, and financially stable career paths in the world. But it's also one of the most misunderstood. In this comprehensive guide, I'll walk you through everything you need to know about becoming a physician, from education requirements and timelines to salary expectations and how this career compares to other healthcare paths like veterinary science and optometry.
Healthcare is evolving rapidly, but the demand for physicians has never been higher. According to the Association of American Medical Colleges, the United States could face a shortage of up to 124,000 physicians by 2034. This projection accounts for both primary care and specialty physicians, and it underscores a critical truth: we need more doctors, and we need them now.
At healthcareers.app, we built our platform because we believe connecting talented individuals with the right opportunities can help close this gap. A career as a physician offers more than just job security — it offers the chance to make a profound difference in people's lives every single day. Whether you're treating a child's ear infection, performing complex cardiac surgery, or conducting groundbreaking research, the scope of what you can do with a medical degree is virtually limitless.
Your journey begins with a bachelor's degree. While there's no required major for medical school admission, most aspiring physicians choose biology, chemistry, biochemistry, or a related science. The key is completing the prerequisite courses — typically organic chemistry, physics, biology, and English — while maintaining a competitive GPA. Most successful medical school applicants have a GPA of 3.5 or higher.
During your undergraduate years, I strongly recommend gaining clinical experience through volunteering, shadowing physicians, or working as a medical scribe. These experiences not only strengthen your application but also give you a realistic preview of what a career as a physician truly looks like day-to-day.
The Medical College Admission Test is a standardized exam that assesses your knowledge of natural, behavioral, and social science concepts, as well as critical thinking and reasoning skills. Most students take the MCAT during their junior or senior year of college. A competitive score, combined with strong extracurriculars and letters of recommendation, is essential for gaining admission to a reputable medical school.
Medical school is divided into two phases. The first two years focus on classroom and laboratory instruction in subjects like anatomy, pharmacology, pathology, and medical ethics. The final two years shift to clinical rotations, where you'll work directly with patients in hospitals and clinics under the supervision of attending physicians. During rotations, you'll explore specialties like internal medicine, surgery, pediatrics, psychiatry, and obstetrics — helping you decide which area to pursue for residency.
After earning your Doctor of Medicine (MD) or Doctor of Osteopathic Medicine (DO) degree, you'll enter residency — an intensive period of supervised training in your chosen specialty. Primary care residencies like family medicine or internal medicine typically last three years, while surgical specialties can require five to seven years. Some physicians pursue additional fellowship training for subspecialties, adding one to three more years.
To practice medicine independently, you must pass the United States Medical Licensing Examination (USMLE) for MDs or the Comprehensive Osteopathic Medical Licensing Examination (COMLEX-USA) for DOs. Board certification in your specialty, while technically optional, is expected by most employers and hospitals. I've seen firsthand on our platform that board-certified physicians receive significantly more interview requests and higher salary offers.
One of the most compelling aspects of a career as a physician is the earning potential. According to the Bureau of Labor Statistics, the median annual wage for physicians and surgeons was over $229,300 as of their most recent data, with many specialists earning considerably more. Here's a general breakdown:
These figures vary based on geography, practice setting (hospital vs. private practice), years of experience, and whether you serve in an underserved area. Many physicians in rural or underserved communities also qualify for federal loan repayment programs through the National Health Service Corps, which can offset the significant cost of medical education.
I frequently hear from prospective healthcare professionals who are weighing multiple career options. Two paths that often come up in conversation alongside medicine are veterinary science and optometry. While each is a fulfilling healthcare profession, they differ significantly in scope, training, and practice.
A career in veterinary science shares many similarities with human medicine. Veterinarians complete a Doctor of Veterinary Medicine (DVM) degree, which typically requires four years of graduate study after completing prerequisite undergraduate coursework. Like physicians, veterinarians diagnose conditions, prescribe treatments, perform surgeries, and manage ongoing health concerns — but their patients happen to be animals.
According to the Bureau of Labor Statistics, the median annual wage for veterinarians was approximately $103,260, and employment in the field is projected to grow 19% from 2022 to 2032 — much faster than average. If you're passionate about animal health but also drawn to the diagnostic and problem-solving aspects of medicine, veterinary science is an excellent alternative worth exploring.
The key differences? Physicians generally earn higher salaries, but veterinarians often report lower educational debt and a more predictable work-life balance, depending on their practice setting. Both careers demand exceptional empathy, scientific rigor, and a genuine commitment to healing.
An optometrist is a healthcare professional who specializes in eye and vision care. Optometrists earn a Doctor of Optometry (OD) degree, which requires four years of graduate study after completing an undergraduate degree. They examine eyes for health and vision problems, prescribe corrective lenses, diagnose conditions like glaucoma and macular degeneration, and in many states, treat certain eye diseases with medications.
The Bureau of Labor Statistics reports the median annual wage for optometrists at approximately $125,590, with a projected job growth of 9% from 2022 to 2032. For individuals who want a healthcare career with strong earning potential, manageable hours, and focused patient interactions, becoming an optometrist is a compelling choice.
Compared to a career as a physician, optometry offers a shorter training timeline (typically eight years total versus eleven or more for physicians), less on-call responsibility, and a narrower but deeply specialized scope of practice. I've worked with many healthcare professionals who chose optometry specifically because it allowed them to maintain a strong work-life balance while still making a meaningful impact on patient health.
Through building and running healthcareers.app, I've had the privilege of connecting with physicians at every career stage. Here are the most valuable pieces of advice I've gathered:
The typical timeline is 11 to 15 years after high school: four years of undergraduate education, four years of medical school, and three to seven years of residency training. Some physicians pursue additional fellowship training, which can add one to three more years. While the timeline is long, the career rewards — both financial and personal — are substantial.
According to the Association of American Medical Colleges, the average cost of attendance for one year of medical school ranges from approximately $40,000 at public institutions (for in-state students) to over $65,000 at private institutions. Over four years, total costs including living expenses can exceed $250,000. However, numerous scholarship, grant, and loan repayment programs exist to help offset these costs.
For most physicians, yes. While the educational debt is significant, the high earning potential means that most physicians can repay their loans within 10 to 15 years of completing training, especially if they're strategic about loan repayment programs and financial planning. The Bureau of Labor Statistics consistently ranks physicians among the highest-earning occupations in the country.
All three are respected healthcare professions with strong job outlooks. Physicians generally earn the highest salaries but face the longest training timelines and highest debt loads. Careers in veterinary science appeal to those passionate about animal health, while becoming an optometrist offers a focused specialty with excellent work-life balance. The best choice depends on your interests, values, and lifestyle priorities.
Primary care specialties — including family medicine, internal medicine, and geriatrics — face some of the most critical shortages. Psychiatry, emergency medicine, and certain surgical subspecialties are also in high demand. At healthcareers.app, we track hiring trends closely and consistently see strong demand across virtually all physician specialties.
A career as a physician is not for the faint of heart. It demands years of rigorous education, emotional resilience, and an unwavering commitment to your patients. But for those who answer the call, it offers something rare: a profession where your daily work genuinely changes — and often saves — lives. Whether you're just starting to explore healthcare careers or you're deep into your pre-med journey, I encourage you to research thoroughly, seek mentorship, and stay connected to the reasons that drew you to medicine in the first place. And if you're exploring adjacent paths like veterinary science or optometry, know that every healthcare career is a noble one. We built healthcareers.app to help you find the right fit — wherever that may lead. Your patients are waiting.
