  • Edward Buchsbaum,
    M.D., F.A.C.A.A.I.

    Dr. Buchsbaum is Board Certified in Allergy/Immunology and Internal Medicine and is one of the founding partners of South Bay Allergy & Asthma. Having treated thousands of patients during his career, he finds it particularly rewarding to now be able to apply recent exciting advances in the treatment of severe asthma, skin allergies and food sensitivities, being able to tell patients that we can more effectively control their allergic condition. Most allergic and immunologic disorders, whether severe and life-threatening or chronic and at times debilitating, have a tremendous impact on daily function. He especially enjoys working with patients and their families, figuring out cause and developing a treatment plan that is effective and easy to follow. Originally from New York, Dr. Buchsbaum and his wife are avid road cyclists and enjoy cycling trips in the states and Europe, skiing, hiking, theater and music. They raised three daughters in Palos Verdes and now get to enjoy their grandchildren living nearby. Next life wishes: English Professor / play in a world-renowned symphony orchestra!

  • Joyce Schoettler,
    M.D., F.A.C.A.A.I.

    Dr. Schoettler is Board Certified in Allergy/Immunology and Pediatrics. As one of the founding partners of South Bay Allergy & Asthma, she most enjoys helping patients identify the cause of their symptoms and targeting these issues, rather than relying solely on medications to suppress symptoms.  She strives to be a trusted advisor to her patients, always looking for practical solutions. Teaching has always been her passion, initially as a faculty member at Children's Hospital Los Angeles, then mentoring physicians in training at Harbor-UCLA for many years; she is now dedicated to helping patients understand their treatment options as the medical field continues to evolve, and together devising a plan that will be in their best interest. She and her husband have raised two children in Southern California and after two decades as a 'soccer mom', she continues to enjoy sports photography, a menagerie of much-loved pets, kayaking, and reading great mystery novels.
