A board-certified internal medicine physician with more than 20 years of experience, caring for adults across Frisco and McKinney, Texas.
My DFW Doctor is a board-certified internal medicine practice led by Dr. Vijay Katari, MD, serving adults in Frisco and McKinney, Texas, with more than 20 years of experience. The practice offers routine wellness and complex, longstanding conditions care, 30-minute visits, an on-site lab for same-visit results, and an optional Direct Primary Care plan.
Meet your physician
Medicine with time to listen
Dr. Vijay Katari has spent more than two decades practicing internal medicine — the specialty devoted entirely to the health of adults. He earned his medical degree from Rangaraya Medical College and completed his residency at WellSpan York Hospital, where he was twice named Resident of the Year.
Today he cares for patients in his Frisco and McKinney clinics and in several assisted-living communities, supporting people with everything from routine wellness to complex, longstanding conditions. He also offers a Direct Primary Care option for patients who want an even closer relationship with their physician.
What ties it together is a simple belief: medicine works best when your doctor has time for you. That means unhurried 30-minute visits, direct access to your physician, an on-site lab for same-visit results, and pricing you can actually understand. It's primary care built around the patient.
We don't push pills. We lay out the options and decide together.
When Dr. Katari's father practiced, the doctor told you what to do and you did it. Medicine has moved on. For most conditions there is more than one reasonable path, and our job is to explain each one — medication, lifestyle change, or both — so you can choose with us.
An example: high blood pressure
If your blood pressure is high, medication is one option — and so are these. Roughly what each can do on its own:
Losing 10 pounds
about 10 points
A DASH-style diet — fruit and vegetables three times a day
5 to 15 points
Eating less salt
about 5 points
Regular exercise
5 to 10 points
These figures are typical, not a guarantee — every person responds differently. Lifestyle changes take time, and medication is often needed for a period until they take hold. There are exceptions, and this is not a standard for every patient; it is an example of the conversation we have with you.
Alternatives first, when they are safe
We tell you what lifestyle change can realistically do, and what it cannot, before adding a prescription.
Medication when it is needed
Some conditions need medicine now, and some need it for a while until the changes take hold. We say which, and why.
Your goals set the plan
Our goal is not to push pills but to give you the best possible care — and that starts with what matters to you.

How we practice
Where we stand
Insurance sits in the middle of almost every decision in American primary care, and patients
are usually the last people told how it works. We would rather you heard it from us. Whether
we can see you today, how often we ask you back, and what a visit is called for billing are
all shaped by rules you did not write and mostly were not shown — so we explain them
plainly, in advance, and we do not pretend a limit is a clinical judgement when it is not.
Some of that is uncomfortable to say out loud. A plan with a low premium can quietly cost you
access when you are unwell. Some follow-up intervals reflect how care is measured as much as
what your body needs. None of it is a reason to be less careful with you — but it is a
reason to be honest, because a patient who understands the system gets better care from it.
What we will not do is let those pressures decide your medicine. We are not here to work
patients for visits, and if an appointment would not earn its place we will tell you so.
What we can do on your plan is set out before you book,
not discovered at the front desk.
Beyond the clinic
Teaching, and talking to the community
Supporting student training
Dr. Katari helps train students in the practice, giving them time alongside a working primary care physician.
Community & radio talks
Dr. Katari speaks to local groups and on the radio about everyday health topics — prevention, chronic conditions and getting the most from primary care. Get in touch to invite him.
Vaccination is your choice
Dr. Katari does not push vaccines. He will talk through which ones apply to your age and history, with the evidence and the trade-offs, so you can weigh it up — the decision is an individual one, and yours to make.
