Both MDs and DOs can specialize in any medical field and have similar practice rights.
- How long does it take to become a specialist doctor?
Becoming a specialist doctor typically requires 4 years of undergraduate education, 4 years of medical school, followed by 3-7 years of residency training in the chosen specialty. Many specialists then pursue additional fellowship training for 1-3 years to further subspecialize. In total, it can take 10-15 years or more after high school to become a fully trained specialist.
