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 6029 Walnut Grove Rd, Suite C002, Memphis, TN 38120.

  1. If you are an existing patient, simply call
    901-685-3490 for an appointment.
  2. If you have not been seen in our clinic before or within the last three years, discuss if a referral is appropriate with your primary care or specialty physician. If they agree, your physician will complete and fax the referral form and necessary documentation.
  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.
