Board of Directors

Jamie Oskin, ND, DHANP
HANP President, Board Member since 2015

Dr. Jamie Oskin is a highly trained naturopathic physician with an expertise in homœopathy and natural pediatrics. While he treats a wide variety of chronic and acute conditions, Dr. Oskin is especially passionate about helping children. Dr. Oskin credits his passion for pediatrics to his early cases as a resident. He recalls helping several children with chronic recurrent ear infections that resolved completely with homœopathic treatment. “Helping those kiddos inspired me to focus my practice in pediatrics because it was so much fun to help them get healthy. I love seeing kids flourish so they can live up to their fullest potential!” Witnessing a child’s transformation is especially rewarding for Dr. Oskin because of the huge impact it has on his patients’ families.

Dr. Oskin has a history of achievement in his field.  After graduating with High Honors from the Southwest College of Naturopathic Medicine (SCNM) in Tempe, Arizona, Dr. Oskin completed a one-year residency in a general family practice and then a second-year specialty residency with a focus in homœopathy at the Southwest Naturopathic Medical Center in Scottsdale, Arizona.

Dr. Oskin is a national speaker on the homœopathic treatment of ADHD and Autism, and his work has been published in Homeopathy Today, the American Journal of Homœopathic Medicine, Naturopathic Doctor News and Review, and Chiropractic Economics (download Dr. Oskin’s articles here).  Additionally, Dr. Oskin plays an active role in education as an adjunct faculty member in the homœopathy department at SCNM.

Dr. Oskin is the current President of the Homœopathic Academy of Naturopathic Physicians (HANP), a member of the National Center for Homœopathy, and the American Institute of Homœopathy (AIH).  He enjoys cooking, hiking, art, music, reading, and spending time with his family and friends in his spare time.

I am serving on the HANP board because of deep sense of passion and devotion to furthering Hahnemannian homœopathy in the naturopathic profession.”

PaisX100_shopGregory Pais, ND, DHANP
HANP Vice President, Board Member since 2015

Dr. Gregory Pais received his Naturopathic Medical degree from the National College of Naturopathic Medicine in 1992.  In 1997 he was board certified in homeopathy by the Homeopathic Academy of Naturopathic Physicians. He served on the HANP Board of Directors from 1997-2007.Dr. Pais has been in practice since 1993 and has been utilizing clinical nutrition, herbal medicine, and physical medicine for 40 years.

When his father died of colon cancer in 1968 Dr. Pais started his journey into traditional medicine. He felt there had to be some other approach to help people heal besides conventional drugs, radiation, and surgery. Physical medicine and nutrition were the first therapies he worked with in the 70’s. During this time he had a professional massage practice and cooked professionally for vegetarian retreats.

From 1991-1992 he was blessed to attend the California School of Herbal Studies (CSHS), the premier herb training institution of its day. There he studied with amazing herbalists—Rosemary Gladstar, ‘Herbal Ed’ Smith, Michael Moore, Cascade Anderson, Michael Tierra, Susun Weed, Christopher Hobbs, David Winston, to name a few.

While attending CSHS he was first exposed to classical homeopathy and naturopathic medicine. He never looked back. There was something about the empirical message of homeopathy that grabbed his attention, impassioned his healing art, and inspired his practice. Wanting a medical degree to inform his work and provide a venue to practice homeopathy he attended NCNM where he delved into its extensive homeopathic library. Though focused on laying the groundwork for his future homeopathic practice, Dr. Pais embraced other core naturopathic therapies-hydrotherapy, food as medicine, and the therapeutic use of herbs. Graduating in 1992 he created his homeopathic practice within the context of being a licensed naturopathic physician.

Over the last two decades Dr. Pais has helped his patients heal, in part, through exemplifying the interrelationship between lifestyle and health. Whether exploring toxin exposure from the home or the environment, enumerating the health dangers of hydraulic fracturing or genetically modified organisms, he has made the case of how not only are you what you eat, but where you live, the air you breathe, and the water you drink.

Working with both adults and children Dr. Pais sees patients with allergies, eczema, asthma, menstrual problems, arthritis, gastrointestinal disorders, and those individuals whose immune systems have been compromised. Of particular note are the many patients with anxiety, depression, panic disorders, eating disorders, and behavioral problems that have been helped by homeopathic and naturopathic care.

Grounded in the science of naturopathic medicine, Dr. Pais’s passion and love for natural living and healthy eating permeates his practice. The depth and power of action of homeopathic medicine is augmented by Dr. Pais’s extensive knowledge and decades of experience in helping people create and maintain an optimum lifestyle.

Dr. Pais truly listens to his patients and strives to understand what they have to say. Considering the mental, emotional, and physical aspects of health, he creates a safe, compassionate environment for healing to take place.

Dr. Pais’s mission is revealed in the following quote: “The physician’s high and only mission is to restore the sick to health, to cure, as it is termed.” From the Organon of Medicine by Samuel Hahnemann

“I’ve rejoined the HANP Board of Directors to help revive the practice of Hahnemannian homeopathy within the naturopathic profession. In particular, I invite any new ND who wants to use homeopathy in their practice to contact me for mentorship.”

This work expands the foundational knowledge of the Homeopathic Materia Medica will be passed on to homeopathic doctors for generations to come.  Outside of Naturopathic Medicine and Homeopathy Dr. Amerine enjoys spending quality family time with her husband and two young girls.

“Never has there been such need as there is today for pure homoeopathy, nor such opportunities for Naturopathic Physicians with great enthusiasm and true purpose, who are thoroughly trained in homoeopathic methods.  If I can assist this process in any way then I know I am giving back to the profession that I so love.”

After receiving his BS in Biology from Drake University in Des Moines, Iowa, he worked as a certified nursing assistant in a medical/surgical unit to continue preparation for medical school. Dissatisfaction with the hospital setting and treatment philosophy led him to question his path to become a physician. His own life-long digestive problems worsened and stress mounted while facing the reality of working in the current disease management system. In expressing these concerns to his acupuncturist, he was introduced to the approach he’d been searching for, Naturopathic Medicine. He declined his acceptance to a local medical school and pursued training as a doctor that embraces the future of medicine while cultivating roots in tradition.

He utilizes the foundational tools of naturopathic medicine (nutrition, herbs, physical medicine, behavioral and mind-body medicine) to create the environment for your health to flourish. He has advanced training in homeopathic medicine to greater individualize patient treatment. As a medical student, he saw homeopathy have a wonderful impact with his friends and family, improving mood, PMS, headaches, joint pains and other complaints.

Dr. Knapp taught Insight Meditation at Coconino County Jail through the Exodus – Inmate Substance Abuse Treatment Program. He also taught anatomy and physiology for 5 years at Arizona School of Integrated Studies (ASIS) and has provided medical and educational outreach at Flagstaff Shelter Services and at domestic violence shelters in Northern Arizona.
