Your emotional health is just as important to us as your physical health.

At Tenny we understand that it can be difficult to take that first step toward getting help for the way you're feeling. Let us help you get back to feeling your very best, inside and out.

What is a PCMH?

A Patient-Centered Medical Home is a model of health care delivery in which your health care is coordinated through your primary care provider's office.


Our office works hard to ensure medications are up to date and that tests ordered by our providers are followed to completion.  

Healthcare can be complex and time-consuming.

At Tenny Internal Medicine we focus on your health so that you can get back to what's important to you.

We're proud to have met the standards of care necessary to be recognized as a Patient-Centered Medical Home (PCMH) by The Joint Commission.
