Welcome to Keystone Primary Care!

We believe in focusing on each patient as an individual with unique physical, social, and mental health needs. In addition to our individualized approach, we provide a friendly and comfortable environment that patients and families of all ages can feel welcome in. Because we serve patients of all ages and walks of life, we believe that our practice can be an excellent medical home for you and your family.

Your Health Is Important To Us!

We strive to provide you with excellent care and help you stay a step ahead of potential health issues. As part of this goal, we want to remind you that we have same day appointments available for acute problems, we encourage you to get your flu vaccine, and that it is important to get your physical before the end of the year.

Flu Season Is Coming Soon

As a key method of avoiding illness, we highly encourage our patients and their families to get the flu shot every year. In order to help prepare you for flu season, we have an article that explains the negative impacts of the flu and why it's important to get vaccinated.

Practice Overview

As your Medical Home/Primary Care Provider, we aspire to provide you with:

  • Patient centered accessible two-way communication
  • Establishment and adherence to evidence-based clinical guidelines
  • A general understanding that you, as a patient, exist within an entire framework of family/work/stress/health/illness, rather than just a 15 minute office visit.

Your obligations as a patient:

  • Act as a team member in your health care by following our recommendations and policies
  • Communicating openly and honestly about your health and self-care
  • Become actively engaged in self-management of any chronic condition
  • Every effort should be made to maintain your healthcare appointments with your usual primary care physician - please communicate which physician you would like to see when scheduling your appointment, either by phone or email
  • In the event that your assigned primary care physician is not in the office and you are actually ill, we can always schedule you with an alternative physician for that visit, but it is important for your long-term health that one doctor, most familiar with you, continues to be the leader of your health team

Sick Visits for established patients:

If you are ill and would like to be seen on the same day, contact the office by phone before noon on that day. We have same-day appointments for sick visits, but often they will fill up by noon of that day. We want to make every effort to keep you from needing to visit an urgent care, and have established policies that allow you to be seen even if we are full, for sore throats, urinary tract symptoms, and asthma exacerbations. 

Staying Healthy At Work

With cold and flu season around the corner, it's important to do what you can to stay healthy this year. By thinking ahead and taking small precautions, you can significantly reduce your odds of becoming sick and spreading it to others. Because illnesses are commonly caught and spread in workplace environments, we have an article that can help you find ways to stay healthy at work.

SameDay Care Centers

Our SameDay Centers deliver excellent care that’s a cut above the typical Emergency Room and Urgent Care experience, at a significantly lower cost. By choosing one of our SameDay Centers, you can be seen after traditional hours or when your regular physician is unable to see you that same day.

After-Hours Support Center (614) 865-3125

If you are a COPC patient, the After-Hours Support Center is available to help you find the care you need. When you call our After-Hours Support Center, a Nurse Practitioner on staff will address your concerns and guide you in the right direction. Mondays - Fridays from 4:00 pm to 11:00 pm and weekends from 8:00 am to 5:00 pm, our nurses can help you schedule appointments with your COPC physician, refer you to a SameDay Center, and help you with prescription refills until you can reach your COPC physician’s office directly (limited to small quantities of your current medications only.)
