Delphi Doctors are dedicated to delivering high-quality, personalized primary care that fits each patient’s needs. As part of that commitment, patients may contact them directly after regular business hours for urgent concerns that cannot safely wait until the next business day or that are especially time-sensitive or sensitive in nature. At the same time, we kindly ask patients to respect that physicians are people too, with families and responsibilities outside of the practice. Our providers prioritize healthy work-life balance so they can continue offering attentive, compassionate care to every patient.

In the event of a medical emergency, patients should call 911 immediately and proceed to the nearest emergency room rather than contacting your doctor first. Once the situation has stabilized, please follow up with your doctor so we can support your continued care.

Delphi Doctors do not admit patients to the hospital, hospital admissions will be managed by the hospital’s care team. Your Primary Care Physician’s role is to advocate for you to ensure you receive the highest level of care coordination all the way through to follow-up.

Delphi Doctors will periodically be out of office to attend conferences or on vacation. During scheduled absences, arrangements will be made for an alternate Delphi Doctor to urgent needs of patients.
