Dr Pak’s interest in medicine crossed paths with Dr. William Rassman's interest in engineering in 1997. Since then, the two have been pioneering hair transplant methods, automation, and instrumentation from the initial FUE techniques and tools to Hair Implanting Pen devices which are routinely used at New Hair Institute (NHI). He has collaborated on U.S. Patents with Dr. Rassman and has been intimately involved with innovative hair transplant surgical techniques incorporating new technology. Dr. Pak brings his engineering and artistic skills to the clinical practice at NHI and continues to develop new surgical techniques and invent surgical instrumentation to further advance the field of hair transplant surgery.
