Preston Medical Associates

Welcome to Preston Medical Associates, PA.!

I�m Pedro E. Checo, MD, FACP board-certified in Internal Medicine with over 34 years of experience in the care of the Adult patients. We�re delighted you have chosen us for your Adult healthcare needs.

Our mission: Quality care for the Adult patient.

And when we say quality, that encompasses the entire healthcare experience: from the time you check in for your appointment to the time you leave, you will be treated with the respect and compassion that you, the patient, deserves.

Let�s be honest- no one relishes coming to the doctor. But like it or not, it is one of life�s necessities. Having said that, does it have to be unpleasant? I would submit to you that, despite your (understandable) misgivings, an appointment with your physician can be informative, reassuring and, dare I say, fun!

D Magazine Best

I'm very proud and humbled to have been named "Best Doctor" in both Dallas and Collin county by D Magazine numerous times. This is particularly gratifying in that to be elected, your physician peers must consider you a good enough doctor to treat their families and themselves. Quite the honor!


At Preston Medical Associates, my staff and I will do everything within our power to make what is traditionally an ordeal into something you may actually look forward to. We are very much aware that you have a choice when it comes to health care. There are many fine physicians in the Frisco area that can provide good, quality medical care. However, I am confident that once you see our commitment to medical excellence, you will never go elsewhere for your Adult primary care needs.

On behalf of my staff, welcome to the practice!
