About our practice

Mid-Ohio Heart Clinic's system of specialty health care may differ significantly from your previous experiences with other physicians

As consulting physicians, we perform many specialized procedures that are often not available elsewhere. Because these special services demand a considerable amount of expertise and time, we practice as a group rather than as individual physicians.

Our group practice allows us to provide patient care in the office as well as in the hospital simultaneously, to perform special cardiac studies and procedures, to be available for emergency heart problems 24 hours a day, 7 days a week, and to consult readily with each other on your case.

The mission of our physicians and staff is to exceed expectations and provide you with the most knowledgeable and sophisticated care available in an efficient and cost-effective health care setting.

To provide this, we rotate hospital responsibilities; therefore, hospitalized patients may be treated by several of our physicians during a prolonged hospital stay. For office visits, our goal is to have you see the physician with whom you are familiar; however, occasionally scheduling conflicts arise. In this instance, you will see another cardiologist in the group or our nurse practitioner who closely consults with the physicians and who has access to your complete medical file allowing this physician to provide you with comprehensive, informed care.

Mid-Ohio Heart Clinic is affiliated with MedCentral Mansfield Hospital, Bucyrus Hospital, and Ashland Samaritan Regional Health System.  We also have satellite offices in Ashland, Bucyrus, and Mt. Gilead, Ohio. Please check with our appointment schedulers for available hours.

Patient Philosophy

  • Patients are the most important people in our practice.
  • Patients are not outsiders to our practice; they are the purpose of it.
  • Patients are not an interruption to our work; they are the reason for it.
  • Patients bring us their needs. It is our duty, both to them and to ourselves, to handle them properly.
