John Herr R.Ph. FIAC



John Herr, R.Ph., FIACP, graduated from Saint John’s University in 1984 with a B.S. in Pharmacy. As a pharmacy student, John was launched into the trajectory that his career would follow when he began practicing compounding in 1983. Since that time, John has practiced in several different compounding disciplines, ultimately specializing in pediatrics, integrative medicine, pain management, and sterile compounding.


John worked at several different retail pharmacies before he purchased an independent retail pharmacy in May of 2000. At Town & Country, John began to develop the pharmacy’s compounding business by serving the needs locally of patients in the community. The compounding business grew so successfully that John was able to open a dedicated, compounding-only laboratory in 2003. Town & Country Compounding became such a successful business that John was able to sell the retail store, enabling him to pursue his passion for compounding full-time.


John is an active member of the compounding pharmacy community. John is passionate about advocating for our industry: he attends IACP’s Compounders on Capitol Hill annually, as well as engaging individual lobbyists to support our causes. Over the years he has served on numerous pharmacy boards in order to support and give back to the profession, including: IACP – Past President and Executive committee member, IACP – Foundation Board, Garden State Pharmacy Owners, Cardinal Regional Advisory Board, Cardinal National Advisory Board, Community Specialty Pharmacy Network Board, and MHA Specialty Pharmacy Board.  He also speaks frequently at patient and professional events on a wide variety of topics in order to educate both the public and healthcare professionals on the value of compounded medications in today’s healthcare system.


John has been professionally recognized numerous times over the course of his career. John has been named the PCCA Compounding Pharmacist of the Month and the PCCA Pharmacist of the Year in 2008. John reports that his greatest honor has been receiving an award from the New Jersey Hospice and Palliative Care organization for the Hospice Pharmacist of the Year, as John has dedicated much of his career to formulating compounds to help with symptom management at the end of life.


John is also passionate about helping patients in pain. John has worked with many practitioners and patients over the years creating non-opioid transdermal cream combinations to help with several types of pain such as inflammatory, muscular and neuropathic pain.

He also has been an advocate of using Low Dose Naltrexone for over 20 years. In fact, before the use of LDN became so widespread, John was mentioned in a book about LDN called: Up the Creek with a Paddle: Beat MS and Many Autoimmune Disorders with Low Dose Naltrexone (LDN) 1st Edition by Mary Anne Boyle Bradley (Author).


John currently holds educational LDN seminars and works with many integrative and functional medicine practitioners to help incorporate LDN into their practices. He has seen it change lives.

David Yeazel, Research Advisor/Educator


David Yeazel brings a unique perspective to LDN, combining expertise in basic and clinical biomedical research with their clinical applications to patient populations. After pursuing undergraduate studies in Psychobiology, with Honors, at Oberlin College, his initial research interests were within primatology, being a National Finalist for the Watson Fellowship for studies within comparative primatology in Africa and Asia.

Within the Department of Neuroscience at Yale Medical School he pursued research in neuropharmacology and psychoneuroimmunology, working towards improved treatment protocols for patients suffering from Parkinson’s disease and schizophrenia. He worked as part of the research team headed by Dr. Patricia Goldman-Rakic which helped to refine the basic understanding of the neuroanatomical and neurophysiological dysfunctions present in schizophrenia, translating those discoveries into clinically useful pharmacological and behavioral treatment protocols.

His research interests broadened into functional medicine as a means to help patients across a wider spectrum of both disease states and health promotion. This involved studies in Public Health at Yale, with concentrations in health services administration and disaster management. David subsequently spent time in Zimbabwe as part of a joint medical relief project between Yale and the World Health Organization bringing mobile aids clinics to remote regions of the country inaccessible to traditional medical care.

David is a nationally sought-after speaker for educating physicians, pharmacists and patients about the benefits of low-dose naltrexone (LDN). He has been a featured speaker for national associations of compounding pharmacists such as the Professional Compounding Centers of America (PCCA) lecturing about how best to use education to succeed in offering LDN. He has also spoken extensively on LDN to clinical practitioners throughout the country, from individual clinics to grand round presentations, summarizing the most recent LDN research and how best to help their patients.

Through monthly educational seminars David has helped to promote awareness to thousands of patients of what LDN is, and how it can potentially help those suffering from chronic illness. 

David previously volunteered as a Research Advisor for the LDN Research Trust, where he was a featured speaker at the most recent LDN Research Trust conference. He was instrumental in helping to coordinate production of a documentary regarding the opioid crisis and LDN’s unique benefits for these patients, recruiting and working with practitioners from Harvard, Brown and Cornell medical centers.
