LLMD Directory

Search ILADS, IFM, LymeDisease.org, and Canadian provincial organizations for Lyme-literate and tick-borne illness practitioners. June 2026: HHS & ILADS strategic partnership integrates the ILADS clinician locator into federal health resources.

Primary referral portals

Start with these organizations for direct practitioner searches.

Each organization maintains its own directory with independent credentialing standards, privacy protections, and search tools.

ILADS — International • all practice types

ILADS Provider Search

Official provider database of the International Lyme and Associated Diseases Society. Includes MDs, DOs, NDs, NPs, and other licensed practitioners who self-identify as treating Lyme and tick-borne disease. Search by postal code and country; select all practice types for the widest results. ILADS does not certify individual providers.

Search tips: Use the postal code of the nearest large city. Set distance to 100 miles. Select "All Practice Types." Leave "Limit results to ILADS PTP" unchecked. If no results appear, email providersearch@ilads.org with your location.

IFM — International • functional medicine practitioners

Institute for Functional Medicine — Find a Practitioner

The IFM directory includes MDs, DOs, NDs, DCs, nutritionists, and other licensed health professionals with IFM training. To find practitioners who work with Lyme and chronic infections, search by country and city, then filter results for clinicians who list infectious disease, chronic illness, immune dysfunction, Lyme disease, or environmental medicine in their practice focus.

Search tips: IFM certification (IFMCP) indicates advanced training. Not all IFM practitioners treat Lyme/TBD. Review individual profiles for keywords: "Lyme," "tick-borne," "vector-borne," "chronic infection," "mold illness," "CIRS," "MCAS," "autoimmune," or "complex chronic disease." Contact the office before booking to confirm they treat your condition.

Testing sources

Specialty labs and diagnostic sources to discuss with a Lyme-literate clinician.

Testing is strongest when the lab matches the clinical question. Serology, immunoblot, PCR, FISH, culture enrichment, urine antigen, and public-health testing each answer different questions; none can rule out every infection alone.

Best-fit testing sources by infection

Clinical question Strong sources to discuss Why clinicians use them
Lyme / Borrelia IGeneX, Galaxy Diagnostics, ArminLabs, Vibrant Wellness, MDL, standard reference labs Expanded Borrelia immunoblot/serology, relapsing fever Borrelia coverage, PCR/direct detection, urine antigen options, and standard two-tier tests when insurance or conventional documentation matters.
Bartonella Galaxy Diagnostics, TLab, IGeneX, MDL, Vibrant Wellness, ArminLabs Bartonella can be low-level, intracellular, and intermittently present in blood. Clinicians often combine antibody testing with direct detection such as digital PCR, enrichment culture, FISH, or species-aware PCR.
Babesia IGeneX, TLab, Galaxy Diagnostics, MDL, Vibrant Wellness, public-health or hospital labs for acute/severe cases Babesia testing may require smear, PCR, FISH, antibody testing, and hemolysis labs. Species awareness matters for B. microti, B. duncani, B. divergens-like organisms, and suspected B. odocoilei.
Mycoplasma MDL, Vibrant Wellness, ArminLabs, Quest/LabCorp/Mayo/ARUP through a clinician Mycoplasma workups may use PCR, IgG/IgM serology, respiratory panels, or broader chronic-infection panels depending on whether the concern is acute respiratory illness, urogenital infection, or chronic overlap.
Other tick-borne diseases MDL, IGeneX, Vibrant Wellness, ArminLabs, state health departments, CDC-supported public-health testing Anaplasma, Ehrlichia, Rickettsia, Borrelia miyamotoi, tularemia, Powassan, Heartland, Bourbon, tick-borne encephalitis, and other rare infections often need timing-aware PCR, paired serology, or public-health lab coordination.

Galaxy Diagnostics

Best fit: Bartonella-first evaluation and stealth pathogen direct detection.

  • Digital PCR and triple-draw options for Bartonella, Babesia, and Borrelia.
  • BAPGM enrichment culture plus Bartonella serology for low-level or intermittent Bartonella.

Testing cautions

  • Acute fever, severe headache, confusion, jaundice, dark urine, low platelets, pregnancy, immune suppression, or no spleen should be treated as urgent medical situations, not routine specialty-lab shopping.
  • Serology can miss early or immune-suppressed disease; PCR and FISH can miss low-level or intermittent infection. Repeat timing during flares may matter.
  • Most specialty testing should be ordered and interpreted by a clinician who understands the patient's geography, exposure history, immune status, symptoms, and medication risks.
Canadian resources

Provincial support contacts and Lyme organizations across Canada.

These contacts are compiled from CanLyme and provincial Lyme organizations. They are patient advocacy and support contacts, not medical providers. Use ILADS and IFM searches to find treating clinicians in Canada.

Important: Canadian practitioner access

LLMD access in Canada is limited. Many Canadian Lyme-literate practitioners are family physicians, naturopathic doctors, or integrative medicine practitioners who do not advertise publicly. Cross-border telehealth with US-based LLMDs is an option some patients pursue, though insurance coverage and provincial regulations vary. Start with the ILADS provider search and the IFM directory (filter by Canada), then contact provincial Lyme organizations for additional leads.

Institutional programs

Academic medical centers and hospital-affiliated Lyme programs.

These programs are associated with universities and teaching hospitals. They generally operate within conventional medical frameworks and may have different treatment philosophies than private LLMDs, but offer research-informed evaluation and can be a starting point for diagnosis.

Practitioner evaluation

How to evaluate a Lyme-literate or functional medicine practitioner.

Finding the right practitioner is as important as finding any practitioner. These questions and criteria help patients prepare for informed conversations.

Credentials and training

  • What medical licensure do they hold? (MD, DO, ND, NP, PA)
  • Are they ILADS members? Have they completed ILADS physician training?
  • Do they hold IFM certification (IFMCP) or other functional medicine credentials?
  • How many years have they treated Lyme and tick-borne illness?
  • Do they participate in continuing education, conferences, or research?

Clinical approach

  • Do they follow ILADS guidelines, MSIDS framework, or another established model?
  • Do they consider co-infections (Bartonella, Babesia, Anaplasma, Ehrlichia)?
  • Do they evaluate for mold/CIRS, MCAS, POTS, and environmental factors?
  • How do they approach treatment sequencing? (Antimicrobials first? Immune support first? Both?)
  • What testing do they use? (Standard two-tier, immunoblot, specialty labs, direct testing)

Safety and monitoring

  • Do they order baseline and follow-up safety labs (CBC, CMP, liver, kidney)?
  • How do they monitor for medication interactions, toxicity, and adverse effects?
  • Do they have clear stop rules and monitoring protocols for intensive treatments?
  • How do they handle psychiatric safety, pregnancy, and medication sensitivity?
  • Is there a documented plan for what happens if treatment causes worsening or no improvement?

Practical considerations

  • What is the appointment availability and typical wait time?
  • Do they accept insurance, or is it fee-for-service/cash-pay?
  • What is the cost range for initial consultation and follow-up visits?
  • Is telehealth available if in-person visits are not feasible?
  • Do they coordinate with your existing primary care physician and other specialists?
