Dr. Derstine first volunteered with HVO’s USAID-funded rehabilitation program in Vietnam, a 14-year project that developed a team approach to caring for people with disabilities.

She also served on the HVO Technical Advisory Group (TAG) for the USAID grant project to establish rehabilitation nursing and strengthen BSN nursing in Vietnam. Dr. Derstine made more than a dozen visits to the country throughout the duration of the project and worked with nursing faculty in Ho Chi Minh City Hue. She also volunteered in Da Nang and helped to develop the Vietnamese Nursing Association.

Dr. Derstine was instrumental in building the nursing education site in Hue, Vietnam and currently serves as project director. She coordinated efforts with the Dreyfus Foundation that led to HVO’s work on a quality assurance project. Dr. Derstine has also volunteered and served as project director for HVO’s nursing education site in Phnom Penh, Cambodia, from 2001 to 2016 and 2017 to 2019.

Dr. Derstine has been active in nursing education and rehabilitation nursing for more than 40 years, serving on the faculty at Temple and Drexel Universities. From 2002 through 2007, she was on the Board of Commissioners of the Commission on Collegiate Nursing Education (CCNE) and served as chair of the board for the last two years of her term.

In addition to her contributions to nursing education in Vietnam and Cambodia, she has worked in Ukraine and India. She is a member of the American Academy of Nursing, the American Nurses Association, and the National League for Nursing, as well as Sigma Theta Tau.

Dr. Derstine is presently engaged in a project with Eternal University School of Nursing in Baru Sahib, India, and has initiated a memorandum of understanding between that school and Drexel University.

Her commitment to global health has been shared with her students, and she is pleased to have some of her graduates now volunteering with HVO.

Susan Harris, MD

Dr. Susan Harris began her volunteer work with HVO in October 2010, when she first traveled to HVO’s hematology project in partnership with EsSalud in Arequipa, Peru. The following year, she became project director. In 2015, when the project with EsSalud was suspended, Dr. Harris arranged an affiliation with the medical school of Catholic University of Santa Maria in Arequipa, at its partner Hospital Escobedo, leading to the project reopening in the spring of 2016. She continued to serve as project director for the new site until the fall of 2019.

In addition to recruiting and screening volunteers for the project in Peru, Dr. Harris has assisted volunteers in planning their educational activities. She has also participated in monthly hematopathology-hematology conferences with Escobedo Hospital to help guide teams in diagnostic management. Her efforts have led to multiple return visits by volunteers. She worked with Dr. Michael Linden, who is a hematopathologist from University of Minnesota and current project codirector for HVO’s hematology project in Peru, to facilitate a hematopathology training visit in the US for a Peruvian pathologist. They have worked together to improve hematopathology diagnoses at HVO’s partner institutions.

Dr. Harris graduated from Columbia University Vagelos College of Physicians and Surgeons and completed her fellowship in hematology at Albert Einstein College of Medicine. Her initial work was on RBC enzymes, including the first description of RPK deficiency. Subsequently, she participated in some of the CALGB studies in leukemia and lymphoma. Her career has included service as head of the hematology clinic, attending physician at the Hospital of the Albert Einstein College of Medicine, and active participation on the transfusion and ethics committees of the hospital. She has also held professorships, and she was in private practice for more than 25 years. She remained on the faculty of Albert Einstein College of Medicine through the end of 2019, supervising the fellows in consultations in the hospital and participating in the hematology course.

Dr. Harris lives in northern Westchester, New York, with her husband. She is a member of Phi Beta Kappa and the American Society of Hematology. In addition to her volunteer work with HVO, Dr. Harris is a singer/songwriter and has released seven CDs.

Patricia Larsen, PT, CWS, OMS

After her second trip in 2018, she became the project director and, a year later, she helped to establish a new project in Kampot, Cambodia, at Sonja Kill Memorial Hospital.

Over the past three years, Mrs. Larsen has worked to bolster the wound care projects at the Phnom Penh and Kampot locations, helping to build a comprehensive wound care curriculum for the medical staff at both locations. Mrs. Many Chheng, the onsite coordinator for HVO’s wound care project at SHCH, noted that Mrs. Larsen has had a significant impact on both staff and patients at the hospital.

After graduating from UVA in 1997, Mrs. Larsen moved to Austin and obtained her Master’s degree in Biomechanics from The University of Texas at Austin. Mrs. Larsen found her calling in the field of physical therapy and began her studies at Texas State University. While her primary interest was in neurologic physical therapy, Mrs. Larsen was drawn to the variety of educational opportunities that come in the acute trauma setting. She began working at University Medical Center Brackenridge in Austin in 2005 and spent 10 years absorbing knowledge from a vast field of patients and coworkers. It did not take long for Mrs. Larsen to develop a passion for wound care. In 2011, Mrs. Larsen completed the requirements and passed the ABWM board exam to become a Certified Wound Specialist.

Over her 15 years of practice, Mrs. Larsen has become increasingly involved in various forms of teaching in the fields of wound care and physical therapy. She has taught at both the university and professional levels, and she has worked with Texas State University as both a regular guest lecturer and adjunct faculty. Mrs. Larsen is a member of the Association for the Advancement of Wound Care, the American Physical Therapy Association, and the Texas Physical Therapy Association.
