About Threlkeld Infectious Disease

As experts in infectious disease, we are called upon regularly to diagnose and treat very difficult and complex issues involving bacterial and viral infections.  While most of our work is done in the hospitals, we do staff and maintain an outpatient clinic to help manage the care of those discharged from the hospital, as well as other patients referred to us by physicians in the Mid-South area for cellulitis, UTI, bone & joint infections, HIV, etc. In addition, we offer the benefit of an outpatient infusion center open 365 days per year within which patients can receive needed IV antibiotics for extended periods. 

Our physicians are also available to assist those traveling to foreign countries with the appropriate vaccinations and instructions for protecting oneself in those lands.

Making an Appointment

Here's a brief, three-step process to use to schedule an appointment with us in our outpatient facility at 1068 Cresthaven.

  1. If you are an existing patient, simply call
    901-685-3490 for an appointment.
  2. If you haven't seen us before, first talk to your primary care or specialty physician about whether a referral to us is appropriate.  If s/he agrees a referral is appropriate, s/he will complete one of the referral forms as provided in the "Forms" section of this website.
  3. Upon receipt of that referral, our clinical manager will review the case, call your provider for additional details, review your case with our physicians, and then call you to schedule an appointment, as appropriate.
