About Alfredo Ermac Jr., MD

In my more than 25 years in practice, I find the most rewarding part of being a doctor is the relationships made with my patients. Helping you navigate your health and well-being over the years and celebrating the successes in your life and the lives of your families is both an honor and a privilege.

My goal as your primary care physician is to provide personalized care emphasizing prevention and wellness. In my MDVIP-affiliated practice, you can experience a warm and welcoming atmosphere, and you can benefit as I share my attention, education and experience. The annual MDVIP Wellness Program is a cornerstone of my practice. My practice offers services, including comprehensive, advanced health screenings and diagnostic tests, that go far beyond those found in concierge medicine practices.

With more than 20 years in northwest Houston, Texas, I serve Cypress, Katy, Tomball, Willowbrook, Champions, Spring, Magnolia, Hockley and surrounding areas. I have relationships with specialists to help you, if needed. As an added benefit, I also offer a family plan in which I can care for your dependents from ages 10 through 26 for primary care outside of the Wellness Program services. If you get sick, you can call me after hours, and my flexible schedule can allow for same-day or next- day appointments.

It would be my pleasure to be your private family doctor. I believe the MDVIP model paves the way for a better doctor-patient relationship because I have more time to spend with you. I look forward to meeting you and partnering as you work towards a healthier life.

I have been seeing Dr. Ermac for over 20 years. He actually listens to his patients. He makes you feel heard, comfortable & safe. Safe in that you know he will not stop until the issue is resolved. He has guided me through lung tumors, respiratory issues & helped watch over my type 1 diabetes. If you are looking for a physician that actually cares, actually listens then Ermac is your man!

Doc has been my primary care physician for 15 years. When he moved out of his old practice, my wife and I followed. I am loving this new office environment. He definitely cares and takes time to listen.

Frequently Asked Questions

Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.

Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.

MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.
