Having Skin in the Game

Patricia Loo, PA-C’s Patient Shares Her Skin Cancer Story


“Having first been diagnosed with in situ melanoma back in 2008, my initial reaction was disbelief and fear. Under Dr. Bortz and Patricia Loo’s thoughtful, comprehensive treatment, my anxieties and fears were quickly allayed, and the melanoma was successfully removed. Over these past 15 plus years, Patricia has earned my utmost respect. With any dermatological condition that may arise, I have the highest trust in her diagnostic and treatment expertise. During my semi-annual checkup, she instills confidence and reassurance by virtue of her experience and knowledge while all along delivering excellent care with thoughtfulness and compassion. Being under Patricia’s care gives me a peace of mind that words cannot adequately describe, and I am happy to report the melanoma has not returned. I am so grateful for the quality of care I have received from her, and I appreciate the friendliness and kindness of her staff. I have been and will continue to be an advocate of Patricia, her experience and Golden State Dermatology.” – David Bowlby
