Quick Fix: Use “Dear Dr. [Last Name]” in the salutation of any formal letter or email to a physician. For patient portals or informal messages, use the platform’s built-in messaging and follow the portal’s guidelines for addressing doctors.
What’s Happening
Writing to a doctor isn’t just about picking the right envelope or stamp. It’s about clarity, respect, and knowing the unwritten rules of medical communication. Whether you’re firing off a formal letter, typing into a patient portal, or sending an email, that first line sets the whole tone. Now, most doctors in 2026 are perfectly fine with digital messages—but some settings still demand old-school etiquette. Get the salutation right, and you’ll come across as professional. Mess it up, and your message might get lost in the shuffle.
Step-by-Step Solution
These aren’t just my opinions—they’re the standard across U.S. medical schools, hospitals, and licensing boards. Here’s how to handle it in different situations.
For Formal Letters (Print or PDF):
- Start with “Dear Dr. [Last Name],” on the first line of the letter’s body. No exceptions.
- Don’t double up on titles. Skip “Dr. John Smith, M.D.”—just pick one.
- DO or MD? Doesn’t matter. Both get “Dear Dr. [Last Name],”.
- End the salutation with a colon in formal letters: “Dear Dr. Williams:”.
For Emails (Professional or Patient Portals):
- Subject lines matter. Use something clear like “Appointment Request” or “Question About My Treatment.”
- In the email body, stick with “Dear Dr. [Last Name],” for formal messages.
- Portals often have their own greetings. If the system gives you a predefined option, use that instead.
For Informal Messages (Text, Chat, or Patient Portals):
- Check the platform’s rules first. Some allow “Hi Dr. [Last Name]” or just “Dr. [Last Name].”
- Avoid “Hey doc” unless the doctor’s actually told you it’s okay.
- Keep it short. State your name, why you’re writing, and any key details.
If This Didn’t Work
No reply? Don’t panic. Doctors are busy, and messages slip through the cracks sometimes. Here’s what to do next.
- Check the portal settings: Some systems only route messages to certain staff. Make sure the doctor is listed as your provider and you’re messaging the right inbox.
- Call the office: If digital communication fails, a phone call guarantees your request gets logged. Use the main number and ask to leave a message for the doctor or care team.
- Visit in person: For urgent or sensitive issues, an in-office visit works best. Walk-ins are usually discouraged, but same-day appointments might be available depending on the practice.
Prevention Tips
Why wait for problems to pop up? A little prep now saves headaches later. Here’s how to stay ahead of the game.
- Confirm the doctor’s preferred name: Some physicians prefer first names. Ask during your first visit or check the practice website. Don’t assume familiarity without their okay.
- Use the patient portal correctly:
- Update your profile with your full name and date of birth.
- Turn on notifications so you don’t miss replies.
- Follow up promptly: Sent a message? Check your inbox regularly. Most portals reply within 24–48 hours during business days. If you’re still waiting after 72 hours, send a polite follow-up.
According to the Association of American Medical Colleges, over 90% of U.S. physicians now use electronic health records, making digital communication standard as of 2026. However, the American Medical Association emphasizes that professional etiquette in written communication remains essential to patient satisfaction and care coordination.
For osteopathic physicians (DOs), the American Osteopathic Association confirms they’re fully licensed physicians who complete rigorous training and meet the same standards as MDs in communication and patient care.
