Our Office Staff

When you visit COR Medical Group, you are treated like an important member of the treatment team. We believe that our patients should have a voice in the course of action taken to meet their individual needs. Our role is to facilitate this by providing detailed information regarding treatment options and expected outcomes from each. One of our commitments is to continually perform in a patient-centered manner. This standard is held across all aspects of our office, from the location we have selected to our staffing and scheduling to the technologies incorporated into our various treatments. Your health is our first concern. In addition to spending time ensuring you are well-informed about your treatment options, we have also put conscientious effort into creating a comfortable environment for you to receive personal health care.

Our office works by appointment because we value your time, and desire to serve you efficiently. Every effort is made to see our scheduled patients on time.

We pride ourselves on preventing serious cardiac conditions as much as possible. But, as cardiologists we still help to take care of patients with serious and complicated medical conditions. We do our best to predict how long each patient will need with the doctor during their visit and we leave openings in our schedule to accommodate unexpected problems as they arise. Despite this, as cardiology is a field prone to life and death emergencies requiring us to prioritize care, occasionally there may be delays in the schedule and ask for your patience and understanding if and when they occur. We will make every effort to keep such delays to a minimum and will do our best to keep you informed of any delays that occur. In rare instances, it might be necessary to cancel and/or reschedule an appointment with little or no notice. We realize that should you ever find yourself as the one in need of our emergency care at the hospital or office or extra time with the doctor, you would be grateful that others understood while waiting. We appreciate your understanding and will try to accommodate your needs as best as we can.

We encourage you, during office visits, to ask for a full explanation of your medical problems. Do not leave with unanswered questions. You have a complete right to ask for all that we can answer concerning your condition. Please do understand however, that for more complex cases, it might be necessary to schedule a follow-up appointment to discuss other non-urgent questions at a later time.

In Case of Emergency or Life-Threatening Medical Condition: call 911 or immediately go to the closest emergency room. The hospital will contact our physician on call.

Appointment Cancellation Policy

How many times have you attempted to schedule an appointment with your doctor or for a test in the office, only to find out that the schedule is full? Unfortunately, some patients are unable to keep scheduled appointments without calling us or canceling. This problem decreases our ability to see patients like you, when you need to see your doctor urgently.

If you need to reschedule or cancel an appointment, we certainly will understand, but please kindly notify us at least 24 hours in advance to avoid an administrative fee.

This policy applies to all appointments to see your doctor or for an in-office test. In particular, patients scheduled for a nuclear cardiology test will be charged $300, and patients scheduled for an echocardiogram (including stress echo) will be charged $200 unless the appointment is cancelled or rescheduled at least 24 hours before the test. Insurance does not cover these costs.

Remember that a no show appointment (or calling at the last minute to cancel or reschedule an appointment) takes an opportunity away from those who need to see their doctor or have a test done urgently. And maybe next time, that will be you.

If you are going to be late for an appointment, please call as soon as possible and we will try to accommodate you as best as we can. This courtesy allows us to accommodate other patients.

Thank you in advance for your cooperation.
