About Dr. Vijay Katari, MD
A board-certified internal medicine physician with more than 20 years of experience, caring for adults across Frisco and McKinney, Texas.

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.
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.

What you can expect as a patient

Prevention first
We catch problems early and plan ahead to keep you healthy for the long run.
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.
