Board of Directors


Dr. Alistair Phillips is the Chief of Congenital Heart Surgery at the Cedars Sinai Heart Institute in Los Angeles, California, and Co-Director of the Guerin Family Congenital Heart Program. He is a seasoned congenital heart surgeon, with over twenty years of experience, operating on both children and adults with congenital heart disease. Dr. Phillips is remarkable not only because of his success in the OR, but because he is a master of new technology and is constantly evaluating how his practice of medicine can harness technological innovative in order to improve outcomes for his patients. Dr. Phillips, along with Dr. Evan Zahn, Chief of Pediatric Cardiology and Co-Director of the Guerin Family Congenital Heart Program, have revolutionized the procedure for replacing the pulmonary valve. What previously required open-heart surgery can now be performed as a much lower-risk hybrid procedure using the skills of the interventional cardiologist and congenital heart surgeon, and by utilizing 3D-printing to simulate the hybrid replacement. Dr. Phillips is an asset to OpHeart as both for his surgical expertise and as an inventor and innovator, and we are thrilled to have his support and input on how to improve outcomes for congenital heart patients.


Dr. Jennifer Arnold is a Board-certified neonatologist and the Medical Director of the Simulation Center at Texas Children’s Hospital.  She has done extensive research on the effects of a simulation-based healthcare training, and is passionate about the applications of 3D-printing in advancing pediatric simulation in critical care situations and improving outcomes.

Further, Dr. Arnold and her family are featured in TLC’s The Little Couple, which documents their lives as little people.  She has a rare type of dwarfism called Spondyloepiphyseal Dysplasia Type Strudwick, which has required that she undergo dozens of surgeries throughout the course of her life.  This has afforded Dr. Arnold a rare opportunity to see the healthcare system as both an inveterate patient and engaged clinician, and she brings a rare and much-needed perspective to the conversation regarding the delivery of healthcare.

In addition, Dr. Arnold is a New York Times bestselling author and has co-written Life is Short and Think Big with her husband, Bill Klein.


Andy Christensen is a pioneer in the 3D printing in medicine and the founder of Medical Modeling Inc., and is uniquely positioned to speak to the benefits of utilizing 3D-printing across specialties. After selling his company to 3D Systems in 2013, Mr. Christensen has become a powerful proponent for the applications of 3D-printing in medicine. He has served as the interim CEO for the World Craniofacial Foundation and as a member of the Board of Directors of e-NABLE, a foundation that is dedicated to delivering quality, low-cost prostheses utilizing 3D-printing.

In addition, Mr. Christensen serves as the Associate Editor of 3D Printing in Medicine Journal, published by Springer-Verlag and is a frequent speaker at medical conferences such as the Radiology Society of North America annual meeting and technology conferences, like SME’s RAPID conference.

We are so honored, lucky and excited to have Mr. Christensen on our Board.

John Gilkes is a seasoned forensic accountant and principal at Deloitte, and has more than twenty years experience in asset tracing and recovery and in the management and conduct of financial/fraud investigations involving wire transfer fraud, bribery/corruption, and extortion. In 2009, Mr. Gilkes joined the expert group of the Stolen Asset Recovery (StAR) initiative to consult on matters relating to asset tracing and recovery. StAR was launched in September 2007 by the World Bank and the United Nations Office on Drugs and Crime (UNODC) as a collaborative arrangement to promote the ratification, domestication, and implementation of the United Nations Convention against Corruption (UNCAC) which in turn provides the legal framework for international collaboration in asset recovery of proceeds of corruption.

Our Board of Directors comprises individuals who represent the wide array of interests in pediatric cardiac care.  We hand-select the innovators, disrupters, optimists, and movers-and-shakers that are dedicated to the care of the holistic care of CCHD families.

We want our Board of Directors’ meetings to serve as a hybrid think tank, 1920s Parisian salon, and the best possible networking event ever organized, where academia, technology, medicine, families, insurance and product development work together to spitball and act on ways in which our heart warriors can be better served.
