  • Referral from your primary care physician. Your insurance company may require the referral to be dated prior to the appointment date.

What if I am running late for my appointment?

  • If you are unable to visit on the appointment date, please notify us 24 hours in advance. This will help us to make that time available to another patient.

Do you accept my insurance?

We accept a variety of insurance plans. We want patients to get the full benefits of their health insurance. Here is a list of some insurances that we DO NOT accept:
  • Any Health spring plans
  • Any Marketplace Plans
We do not accept Medicaid primary, but do accept as secondary coverage. For more information, please call your insurance company to ensure that we are in their network.

What should I expect from my visit?

We provide proper diagnosis with suitable explanations answering your reasonable questions and give a written treatment plan. We expect you to understand your diagnosis, ask reasonable questions, provide distraction free intervention and follow together the jotted treatment plan. We may refer to dietary education, radiology services and laboratory services as needed. If necessary, you may be referred out for surgical services too.

Would you be willing to discuss my diagnosis and treatment plan further if I am not satisfied?

We are more than happy to provide a healthy discussion. We will not be offended if you seek consultations or referral elsewhere and will help transferring your care.

What is the usual length of an appointment?

You should expect a 2-hour visit from check in to check out for first-time patients and at least 1 hour for follow-up patients.

How can I contact your office?

Our front office can be contacted by phone during work hours at (409) 833-6900. You can use our patient portal to contatct us at any time.

Do you provide non-traditional treatment methods?

No. We are not involved in providing non-scientific care or practice away from standard of care - like prescribing thyroid meds for symptoms with no thyroid disease or prescribing harmful steroids or testosterone without proper diagnosis or management. We don't prescribe if the treatment is harmful or non-scientific.

Do you use physician extenders in your practice?

Yes, we have nurse practitioners, physician assistants, and students who may contribute to the provision of your care. Our nurse practitioner has been working alongside our MD since 2006. They provide similar care and treatment plans and are subjected to regular review and continuing education. There are patients who wish to see NP or MD only. If you have any preference, please let the front desk know so that we could set it up. However, the wait time may be longer if a specific person is requested.

Prescription refills?

We call in refills the same day for requests made by phone, faxed from pharmacy, or sent electronically.
