ISEAI President

“I believe in ISEAI, because I believe in those who make up ISEAI. Our members are driven to help their patients. Our leaders are driven to help increase all of our knowledge and awareness, to help our respective patients. ISEAI is made up of people who are willing to stand in the gap for those who are often marginalized by friends, family, and even those in the medical community. That’s worth my time, and my energy. These are the people I want on my team, those I want to align myself with… those I want to call my professional family. I’m proud to stand with those who make up ISEAI.”

Lauren Tessier, ND

ISEAI Vice President

“I stand in service to ISEAI, because I believe that the healthcare profession can do better when it comes to assisting people suffering from complex chronic illness; and ISEAI is positioned to do just that. We are a thriving community of  well intentioned and well educated physicians who are at the ready to facilitate a sea change in the larger medical paradigm- and I couldn’t be more excited about it!”

Mark Su, MD, FAAFP, is a seasoned physician who is dedicated to patient advocacy and care, and passionate about learning. His pioneering practice in Newburyport, MA provides complex patients specialized expertise in environmentally acquired illness in either focused consultation, or incorporated within a primary care model. Mark’s commitment to ISEAI stems from his joy of seeing patients recover and heal from mold and biotoxin illnesses.

Mark strives to passionately and energetically guide this diverse and inclusive community of like-minded practitioners and patients toward becoming a significantly greater force of influence, bringing awareness of environmental drivers of chronic illness to yet greater numbers of practitioners and patients. He is dedicated to furthering ISEAI’s mission to reduce human suffering by helping patients discover the root causes of their chronic illnesses and symptoms, and in doing so, offer people the priceless gift of hope for healing. His approach to patient care, learning, and leadership is one and the same: inclusive, detailed, information gathering; and collaborative, thoughtful decision-making.

Personal Care Physicians of Greater Newburyport –

Lauren Tessier, ND, is a Naturopathic Physician licensed by the state of Vermont. After earning her Doctorate of Naturopathic Medicine from Bastyr University in Kenmore, Washington she returned home to New England. It was in central Vermont that Dr. Tessier established a successful integrative health clinic. After a few years of practicing Functional & Integrative Medicine, Dr. Tessier noticed that there were some cases that were not responding as well to treatment as typically expected—especially the cases with a history of exposure to mold and water damaged buildings. Driven by her curiosity and desire to help difficult cases, Dr. Tessier started treating biotoxin illness in 2013 and became a CIRS certified physician in 2016.

In response to growing interest in her expertise, Dr. Tessier established Life After Mold; the East Coast’s only CIRS certified Naturopathic practice. Life After Mold services patients suffering from multi-symptom, multi system illness, complicated by co-morbid conditions such as MCS, MCAS, and chronic infections- including Lyme & co infections, EBV, CMV, etc. Dr. Tessier’s practice is in Waterbury, Vermont.

The e-book “Mold Prevention: 101”, authored by Dr. Tessier has been widely circulated and its suggestions implemented by many worldwide. Dr. Tessier sees patients at her Life After Mold practice and offers consultative support for professionals and clients nationwide.

Kellyn Milani, ND

ISEAI Secretary

“I joined ISEAI to be a part of the movement of giving a voice to patients who have chronic complex illnesses and who are often marginalized by mainstream medicine. ISEAI is a community of practitioners who motivates each other to continue to learn and grow by pushing the envelope of medicine. It’s an added bonus that each ISEAI member who I have interacted with is inspirational! I am honored to serve on the board of directors and to be able to advocate for the inclusion of environmentally acquired illnesses in mainstream medicine.”

Michael Schrantz, CIEC, CMI, BPI-BA/EP

Michael Schrantz, CIEC

ISEAI Treasurer

“ISEAI is a community of like-minded professionals seeking to better understand the complexities of chronic illness and low-dose environmental-exposure concerns. As an IEP, I am grateful to find myself surrounded by colleagues who also understand yet, at times, struggle with the diversity of environments and conditions surrounding our clients. ISEAI is a place where examining minds are welcome. A place to learn. A place where ideas or assumptions can be respectfully challenged, even tested, for the good of service to our community.”

Kellyn Milani, ND, is a naturopathic doctor who focuses on biotoxin illness, chronic illness, and regenerative medicine. She founded Remedy Health, a CIRS focused clinic in Bozeman, Montana, in 2018 and practices in Auburn, California as well.

Dr. Milani has been treating patients with biotoxin illness since 2013 and completed the Dr. Richard Shoemaker certification in Chronic Inflammatory Response Syndrome (CIRS) in 2015 and the Dr. Richard Horowitz certification in Healing Lyme & Co-Infections in 2019.

Michael Schrantz, CIEC, is an experienced Indoor Environmental Professional (IEP) who owns and operates Environmental Analytics, which serves to educate and guide clients with their environmental exposure concerns around the globe. He views ISEAI as a family of professionals who are working together to better understand the many challenges that come with chronic illness and the built environments we occupy. You can learn more about Michael by visiting his website, Environmental Analytics.

“My current experience as an ISEAI board member has allowed me to see how the day-to-day operations work, including how important financial management plays a role in the health and growth of a non-profit organization. During this experience, I realized I might be able to serve a higher role and help out with the overall aspects of financial management and vision towards the future. My hope is to both strengthen staff infrastructure that allows for a greater outreach and response to both practitioners and patients, as well as continue the educational track ISEAI is pursuing to increase the knowledge of Environmentally Acquired Illness worldwide.”

Why They Serve – Board Member Statements

Mary Ackerley, MD

ISEAI Board Member & Past President

“It’s a great feeling to know that something you are doing is for the greater good and is making a difference. I was driven as a cofounder to create a professional nonprofit association that could educate a much wider swath of healthcare providers about the dangers of mold. I have seen so many patients labeled psychiatric and treated with meds that barely work, if at all, when the real cause was neuroinflammation from environmental toxins. Along the way a group of dedicated individuals every bit as passionate as I am in driving education and research into the silent poisons has gathered and helped grow this organization beyond anything I originally envisioned.

Lori Allen, RPh

ISEAI Board Member

“ISEAI is important to me because it gives credibility to issues that patients are experiencing and doesn’t yet have the full attention of mainstream medicine. I donate my time serving as an ISEAI board member because I believe ISEAI will move environmentally acquired illnesses into mainstream acceptance. Think of it as global warming applied to medicine.”

JW Biava

ISEAI Board Member

“Having been personally affected by mold and VOC contaminated environments, as well as having worked with thousands of clients who have experienced the debilitating effects of environmentally acquired illness, I am firmly committed to the mission and goals of ISEAI. As an advocate for affordable testing and treatment solutions for those affected by environmentally acquired illness, I am highly motivated to work with the ISEAI community to ensure the protocols and guidelines we endorse are not only highly effective and proven, but also widely accessible across all socioeconomic levels. It is especially exciting to work with this accomplished group of EAI professionals to help develop ISEAI into the premier organization for the dissemination of information pertaining to EAI, building a legacy for future generations.”

Jill Carnahan, MD

ISEAI Board Member

“I have been serving on the ISEAI board since its inception because I believe in the mission of restoring health to individuals with environmentally acquired illnesses through clinical practice, education, and research. I want to do everything in my power to ensure other healthcare professionals are being educated in the epidemic of environmentally acquired illness that is devastating our patients. I strongly believe in the mission and vision of this organization in taking us into the future of critical thinking and problem solving in medicine and coming up with innovative new solutions for our most complex patients.”

Georgina Hale, MD

ISEAI Board Member

“I am serving on the ISEAI board because I want to assist in increasing the awareness of illnesses that are not explained by modern medicine’s current diagnostic criteria and paradigms. I believe we need to look to our environment that has changed immeasurably, because our knowledge on how it affects our health is less than cursory. As a result, we as medical doctors default to ‘everything is fine’.”

Jessica Jellison, MD

ISEAI Board Member

“I joined ISEAI because it fulfills a need in our medical community to understand better environmentally acquired illness. I’m able to join colleagues who are navigating the complexity of mold illness and other environmentally acquired illness and give credibility to this medicine.  It’s a wonderful platform for education, questions, answers, and fosters camaraderie. I’m blessed to be surrounded by a group of individuals whose values to gain knowledge, wisdom, and expand education on environmentally acquired illness are similar to mine. Together, I know ISEAI can gain traction in our medical community to educate and make a difference.”

Todd Maderis, ND

ISEAI Board Member

“I serve on the ISEAI Board because the organization is committed to increasing awareness and educating healthcare providers about environmentally-acquired illnesses – the causes I see most commonly in my patients. This area of medicine is largely overlooked, so many people suffer unnecessarily for years. I am committed to ISEAI to help increase awareness of the role environmental toxins, infection exposure, and subsequent immune response have on human health.”

Kelly McCann, MD

Kelly McCann, MD

ISEAI Board Member

“It has been the mission of my medical career to embrace the depth of connection between health and all the myriad of factors of a human being’s existence. Our genetics, nutrition, lifestyle choices, thoughts, beliefs, emotions combined with our environmental exposures, microbial diversity, detoxification capacity all culminate in WHO we are and HOW we are in the world. As a practitioner, continual education is paramount in order to help patients get well, and understand their WHY. ISEAI is the professional organization that aligns with my vision and offers the platform of education needed in this increasingly complex world. It is only when we view health and dis-ease through this broad lens will we overcome chronic illness and achieve wellness.”

Nafysa Parpia, ND

ISEAI Board Member

“I have spent the last decade helping patients recover from mystery illnesses. It is my clinical experience that a significant underlying cause of their immune dysfunction is low-level environmental toxicant exposure. This is an area of medicine which is currently not well recognized. There is hope for these patients who so often are misunderstood, undiagnosed and isolated. There is hope for the restoration of their health by way of a change in the paradigm of the treatment of patients with chronic illness. I stand behind the vision of ISEAI in helping to create this much needed shift through education, research and medical practice.”
