About Robert John Mills IV
Johns Hopkins Physician
Background
Robert Mills, D.O., joins Johns Hopkins Community Physicians with many years of experience as a family medicine physician. He grew up in New Jersey and attended Villanova University for his bachelors of science in biological sciences. Upon completion, he earned his doctor of osteopathic medicine from Philadelphia College of Osteopathic Medicine. As a provider, he finds it rewarding to get to know his patients on a more personal level and help them manage their health throughout their lives. He understands medicine is challenging on both sides - for his patients and as a provider - and he knows that providing a comfortable environment, where patients feel heard and respected, is what makes a good patient-physician relationship.
Dr. Mills lives with his wife in Canton and has one too many pets, including four cats and a dog.

Excellent Doctor
- 5 out of 5 starsReviewed on 3/6/2026
This was my first visit with Dr. Mills as a new primary care provider. He was very easy to talk to, remained engaged with me, covered my medical history very efficiently, was knowledgeable about my conditions, and did not appear to be rushed to see other patients or leave the room for other reasons. He seemed genuinely interested in hearing from and learning about me, and tuned out any competing distractions. Also, he was right on time! My wait time was extremely minimal.

Dr Mills is fantastic!! If he's not already, he should be part of working groups to advise on best practices for patient care as it's clear he stays current on best practices for care and management.

I've been going to this specific clinic for at least 35 years, and I can say, without fear of hyperbole, that Dr Mills is probably the best provider I've seen there. He maintains eye contact and listens. He doesn't stare at the computer while you talk to him. He offers suggestions, not deliver ultimatums. Please, please don't let him leave. It seems like we get new providers every 2-3 years.

I've had many, many doctors over the years due to moving around and different issues I have. Dr. Mills is by far my favorite doctor I've ever had. He's kind, compassionate, funny, patient, spends lots of time with his patients to truly understand their concerns, but also them as a person, and he's very smart and links things from past visits and specialist doctors to current issues. All the best qualities for any doctor, but especially a primary care doctor! I'm so glad I randomly chose him from a list when I moved back to baltimore last year!

The physician is incredible. He is one of the most professional and relatable physicians I have ever had in my care plan. Dr Mills is a complete asset to the program and I sincerely hope he is recognized by the JH governance for his management style and patient care. It's everything that someone would want in an attentive physician.
