Volunteer Spotlight

Jung On Ahn, RN
(San Mateo)
2013 Spirit Award Recipient - Jung On Ahn, RN, Kaiser Permanente Medical Center, South San Francisco

Jung On has been volunteering with OA as an OR nurse from the inception of the program at Kaiser Permanente South San Francisco in 1998.  Back in Korea, Jung On always volunteered through her church, but when she came to the United States, she had difficulty finding a way to give back until she found Operation Access a perfect fit. “It was effortless to get involved with OA…(it) was so convenient; it was right under my nose,”
Jung On’s work with our patients is infused with her good will. “OA is part of my life.  We get our life, health and blessings from the lord.  There has got to be a way to give back and share. I have received a lot in my life and I am so grateful for the ability to volunteer.”


 Gary Barth, MD
2013 Champion Award Recipient - Gary Barth, MD, 4th Street Laser and Surgery Center, Sonoma

After having volunteered overseas for years in places like India and Nepal, Dr. Gary Barth established a foundation to provide eye surgery for people in his own Sonoma County community, particularly people who work in the vineyards and other agricultural jobs.
Coincidentally, about that time, he found out about Operation Access, and jumped into volunteering with us. For the past two years, Dr. Barth has treated patients on a case by case basis, but he had bigger ideas. On October 26, 2013, “Make a Difference” day, our mutual efforts culminated in a day of surgery during which he, his colleagues and their staff donated their skills and time to correct the vision of two dozen patients.
All involved were so inspired, they are hoping to do it again on “Make a Difference Day” 2014. 


Philip Chung, MD
(San Francisco)
2013 Legacy Award Recipient - Philip Chung, MD

Dr. Philip Chung has been volunteering with Operation Access since he began practicing at CPMC in 2008.  To date, he has treated 74 patients and accepts one new patient every month.  Although Dr. Chung is a colorectal surgeon, he does not limit his scope and we also depend on him to provide cholecystectomies and hernia repairs.
Dr. Chung loves to hear about how patients are getting their lives back together during post-op visits. He recalls one woman, a seamstress, who offered to sew him anything he wanted because she was so happy to be working without pain. On volunteering, Dr. Chung says, “It is a privilege to be able to take care of others.  If you needed help, who would you want to take care of you?  I would want someone who enjoys it as I enjoy volunteering with OA.”


Brian Delfanti, MD 
2013 Legacy Award Recipient - Brian Delfanti, MD, Kaiser Permanente Medical Center, San Rafael

Dr. Brian Delfanti receives the legacy award in recognition of his twelve years of dedicated volunteer service and his commitment to caring for the underserved in Marin County. He has never said “no” to a patient referral and, if he is unable to perform a procedure, he will do everything he can to find an appropriate specialist who will take on the case.
Dr. Delfanti has always been very motivated to use his surgical skills to help those in need. He believes that, “being able to care for these patients is an honor.” He knows that insured patients will always have access to care, but being able to help patients who don’t have that security makes him appreciate the contribution he can make to the community. He finds caring for OA patients very emotionally rewarding. 


James Harwood, MD
2013 Spirit Award Recipient - James Harwood, MD, Santa Rosa Memorial Hospital

Dr. James Harwood called our office in early 2009 to “find out what this whole Operation Access thing is all about” and, satisfied with what he found, became one of our most dependable and enthusiastic volunteers.
“When I was a surgery resident at UC San Francisco,” Dr. Harwood explained, “I had the good fortune to rotate through SF General Hospital, where there is a large indigent population. I always felt that surgeons have an obligation to give back to society once they become successful. Operation Access presented an opportunity to do just that. It has been very satisfying to provide surgical care for these appreciative patients.”
And Dr. Harwood’s patients certainly let us know how they feel. “Thank God and thank you Dr. Harwood, because now I have the possibility of being a normal person, like you told me I would.”

Dr. Kasper has provided over 20 life changing surgical procedures ranging from myomectomies to laparoscopic hysterectomies. Despite the complexity of some the cases we ask her to accept, Dr. Kasper has never refused to treat an OA patient.  She also volunteers at the John Muir Health Mobile Health Clinic through which she has connected patients with Operation Access.  


Sabrina Kidd, MD

When we recently asked if she could expand  her scope to include GI services in addition to colorectal care, she agreed immediately and without question.
Dr. Kidd always takes the time to fully explain a situation and to ensure that every patient completely understands his/her condition and the procedure.
