MedStar St. Mary's Hospital is pleased to welcome Harry Gill, MD, PhD, to our medical staff community. In addition to his medical doctorate and board certification in psychiatry, Dr. Gill holds a double-major doctorate degree in neuroscience and cognitive psychology from Iowa State University. As a leader in behavioral health and psychiatry, Dr. Gill evaluates patients at our hospital in Leonardtown, and now at our primary care office in Great Mills, through a partnership between Axis Healthcare Group and MedStar Health. 

Q: How do patients benefit from expanded mental health services?

A: We’re focused on providing a continuum of care for patients. With a large shortage of psychiatrists nationwide, we are excited to offer mental health services in two different areas of St. Mary’s County. It provides patients with more options – inpatient and intensive outpatient psychiatric care at MedStar St. Mary’s Hospital and outpatient assessments and treatment at the Great Mills location.

Q: Why is it important to co-locate services?

A: I believe in an integrative model of care that provides patients a “medical home” that includes their mental health. It is for this reason that being “embedded” in MedStar St. Mary’s primary care office in Great Mills had such an appeal to me. Instead of driving all over town for appointments, one stop can help our patients meet many of their medical needs. Frequently, patients suffer from two or more different ailments, such as diabetes and schizophrenia, requiring the expertise of a primary care physician and a psychiatrist. In this case, patients can benefit from the convenience of seeing both doctors, during separate and confidential appointments, without leaving the building. Also, these doctors can partner and coordinate their care for the same patient.

Q: When should someone seek the help of a mental health professional?

A: Just like any other illness, it’s important not to wait too long and seek help early. An early diagnosis and appropriate treatment produces better results. It’s normal to experience sad feelings or to worry during your day-to-day life. However, it’s important to recognize signs of a more serious problem. If you experience anxiety or depression or any other feeling that impairs your ability to function or enjoy life, a mental health professional can be of help.
