What’s your risk level?

How’s your heart health? Are you at risk for a heart attack or stroke? Your doctor can do a screening to find out. The screening looks at your cholesterol levels, blood pressure, and other factors to determine your risk. If you need to lower your risk, together with your doctor you can decide what health habits to change and what treatment is best for you. Find out more about screening for heart attack and stroke risk here.

We will continue to participate in all Cigna plans. Unfortunately we will no longer participate in any United Healthcare plans as of 2/1/2022. We continue to work with United and hope to be back in network at some point in the near future. If you have out of network benefits with your United plan, you can be seen in the office and we will submit claims on your behalf. Please continue to visit this webpage for more updates. If you have any questions, please contact our office.
