Karen K. Leong, M.D. – Plastic Surgeon – Upland, CA

Dr. Karen Leong

Upland, CA board-certified plastic surgeon Dr. Karen K. Leong embraces the nuances of beauty and graceful aging at her practice. Her understanding of the structural and soft tissue changes in the face and body allow her to treat each person with a thoughtful and comprehensive approach. By combining empathy with a gentle yet direct manner, she journeys with her patients through their rejuvenation process. Along with a love of surgery comes her great respect for the intricacies of the human body, particularly in the area of feminine health. Vaginal rejuvenation and bio-identical hormone therapy (femi-surgical enhancements) are part of Dr. Leong’s comprehensive approach to women’s sexual health and well-being. She has medical admitting and surgical privileges at Hoag Hospital, OC Global Medical Center, Mission Hospital and is credentialed to operate at the Reconstructive Surgery Center, Hoag Surgicare, and Newport Center for Special Surgery.

Skills and Specialties

As a woman in a male-dominated field, she has an opportunity to start the conversation with her female patients about changes to that intimate area whether it’s due to childbirth, trauma, or menopause. She has traveled within the U.S. and abroad to expand her experience under the tutelage of giants in the field, and she is now excited to share with her patients those cutting-edge aesthetic techniques for the face, breast, body, and skin. Beyond operating, Dr. Leong keeps her artistic eye fresh by staying involved with skin care, injectables, and lasers. These nonsurgical services enhance her surgical practice. She absolutely believes that the better quality skin you begin with and the more knowledge you are armed with for maintenance, the happier her patients.


Dr. Leong completed her undergraduate studies at the University of California, Berkeley and continued her medical education at Drexel University College of Medicine in Philadelphia, PA. Her academic excellence brought her to Ivy League Brown University where she spent seven years honing her clinical skills in a rigorous combined general surgery and plastic surgery residency. Dr. Leong continued to cultivate her education when she was accepted into a fellowship in aesthetic plastic surgery; one of the select few chosen for these highly competitive and coveted positions. She was fortunate to mentor under and learn from several renowned surgeons both in the U.S. and internationally, including the then president of the American Society of Aesthetic Plastic Surgeons. 

Professional Memberships

She has been in practice for two years and is constantly trying to improve herself by attending meetings, volunteering with local medical missions, serving on editorial boards, and observing other surgeons. Life has been very full. She can't wait for the next chapter. Dr. Leong is proud to be a member of the following organizations:

  • The American Society of Plastic Surgeons
  • The American Society for Aesthetic Plastic Surgery
  • The American College of Surgeons
  • The Orange County Society of Plastic Surgeons
  • Plasticos Foundation
  • Reshaping Lives California


To be plastic means being easily shaped or molded, so to Dr. Leong, plastic surgery is fluid and creative. She believes her specialty is taking what she is given and her patient’s needs to build a result that is functional, natural, and beautiful. It is work that is challenging, stimulating, and fun. After each case, she asks herself, "What can I do differently next time? What can I do better?” because at the end of the day, she loves what she does because it pushes her to grow continually and to never accept that good enough is good enough. So why aesthetic (cosmetic) surgery? Plastic, reconstructive, or aesthetic surgeries are surgeries that give back. She believes that they don’t just remove or restore what was there — it enhances. Someone told her once, "The hardest surgery is making normal look better." Dr. Leong took this to heart. Being a cosmetic surgeon means she has the responsibility of instilling confidence in her patients about their appearance, improving their self-image, and their ability to interact with others. Natural beauty helps you feel as good as you look. 

When you come in for a consultation and for every visit following, Dr. Leong wants you to feel cherished. She is honored that you are sharing your concerns and goals with her to achieve your best self. She promises to be honest with you because changing your appearance is a big commitment. She wants all potential patients to know, "You and I need to build a relationship that will last. We are on this journey together. I thank you for trusting me to care for you."
