Becoming a Member of ISEAI

ISEAI has several membership categories, with different levels of benefits. Please read below, to determine which category best fits your needs. To become a member, submit your completed application along with the required supporting documents and a one time, nonrefundable application fee of $25 (fee does not apply to Affiliate members). The Membership Committee meets regularly to review applications and you will be notified of your application status after they meet. Approved applicants then pay the full annual membership fee appropriate to their membership category. Applications that are not approved for membership may be appealed to the Board of Directors.

Those who apply for Full memberships must meet higher sets of requirements. We are obliged to gather background information on applications for this level of membership. This includes the option to set up a profile on our referral lists for those seeking professional help with health, environmental, or legal matters related to environmentally acquired illness. Meeting these higher credentialing standards will speak to the advanced professional qualities sought by ISEAI in our Full members.

Membership Ethics Policy

The ISEAI Membership Ethics Policy is based on and complementary to the high standard of medicine expected of its Members and Diplomates. Members who are health care professionals must adhere to the following ethical standards. A member who violates these standards may be counseled or expelled from ISEAI.

Each ISEAI health provider must:

  1. Seek to develop and maintain core competencies in environmentally acquired illness (EAI) and seek to maintain a high level of professional qualification through continuous education, as EAI is an evolving field of expertise.
  2. Practice and promote evidence-based medicine in EAI. Members must not claim results or outcomes unsupported by documented, verifiable evidence. When members have an opinion regarding treatment that is based on personal or financial ties rather than clinical judgment, they nevertheless must share alternative perspectives and treatment options with patients.
  3. Comply with all applicable laws and regulations governing their individual scope of practice.
  4. Conduct themselves honestly, fairly, and in good faith, and treat patients and other healthcare professionals with respect.
  5. Uphold these standards of professionalism. A member who knows that another ISEAI member has engaged in conduct that violates these standards or otherwise could cause harm to patients must report this to an officer of the ISEAI board of directors.
  6. Present any research findings with complete honesty and accuracy, and, if conducting research, shall behave ethically towards human subjects. Members who publish research must disclose any conflicts of interest that are arguably relevant to the work published.
  7. If prescribing or recommending a product or service (other than direct medical care) from which they would profit, provide patients with full and complete disclosure, orally and in writing, of their financial interest in the product or service.
  8. Seek to provide a portion of services to patients who cannot afford to pay a provider’s usual fees.
