Dr Pang Chi-wang, Peter is a guardian angel for people who have suffered from cleft lip and palate birth defects. An active volunteer for humanitarian aid since 1999, Dr Pang goes regularly to underdeveloped areas to operate on people to close their clefts and stop their sufferings. Years on, Dr Pang also actively promotes health education in both the Mainland and Hong Kong.

In the Mainland, many people have cleft lips and palates. With their facial deformities and inability to pronounce and communicate properly, cleft sufferers face discrimination and have difficulties in integrating into society. Because of the problems, some parents even abandoned their own children."Cleft lip and palate sufferers do not have risk of death. But after our cleft repair surgeries, patients and their family members will not be discriminated against and ridiculed. With similar appearance to others, they can live a normal life and integrate into society," Dr Pang said. "In one case, a child with a cleft lip and palate had never been hugged or kissed by his parents since birth. After his cleft was closed with our surgery, the child immediately wanted to hug and kiss his parents."

As a plastic surgeon, Dr Pang hopes to use his professionalism and abilities to safeguard the dignity of patients and the underprivileged. His mission motivated him to join charity organization, Operation Smile International, to provide surgical repairs to the needy born with clefts. Over the past 12 years, Dr Pang took part in its 25 missions, giving cleft repair surgeries and treatments to almost 700 patients in such places as China, Philippines, Kenya and Cambodia.

In 2005, the active humanitarian took up the role as a member of the Executive Board of Operation Smile China Medical Mission. He has appealed for more medical staff to join them as volunteers, and actively raised funds for the organization. In 2007, Dr Pang helped establish the first Operation Smile Charity Hospital in Hangzhou to provide surgical repairs, dental services and speech therapies to cleft patients. But his mission has not ended. Dr Pang is now planning to build another medicial centre in Kunming that will provide free on-site reconstructive treatments for cleft patients in need. Dr Pang's persistence in volunteering has made him a role model for the new generation of volunteer doctors who have committed themselves to helping the needy.

In 2009, Dr Pang and his friends formed Happy Health Society, a charity dedicated to health promotion and healthy living. They have organized seminars on a series of health topics like mental health and heart disease prevention. Dr Pang had also served as Club President of Rotary Club of New Territories to organize various community services, like promoting the prevention of polio and Hepatitis B in China.
