Chief Resident, Periodontic Department
"I once had a diabetic patient who presented with generalized severe chronic adult periodontitis. His oral hygiene was non-existent. After full-mouth osseous surgery and debridement, the patient transformed into a new person. During subsequent follow-up and recall visits, he not only kept his mouth remarkably clean, but he also changed and improved his entire outer appearance. He had his hair styled, got new sleeker looking glasses, got a whole new wardrobe, and lost 25 pounds. His diabetic status, which was borderline uncontrolled was now controlled. His hemoglobin A1C decreased from 7.2 to a 5.8 after the periodontal surgeries. He always credited the start of his amazing transformation to his periodontal surgeries."

"A young lady from Pomona that had a severe underbite was selected by a local dental group to receive pro-bono care by an oral surgeon & myself as part of a community project to assist those in need of special care that could not afford it. After the treatment was completed & I showed the mother the before & after pictures, she wept tears of joy to see how beautiful her smile & facial structure appeared & the dramatic improvement in her daughter's self-esteem. It was very rewarding to see the impact that we had on her appearance as well as the transformation it had on her personality & life. The patient & her parents couldn't stop smiling & thanking us for the “miraculous” transformation that they had seen in their child."
