Dr. Hilda Riderer was born and raised in Romania and moved to California with her family when she was a young girl at 9 years old.
She always had a passion for medicine so she pursued an education in the medical field going to osteopathic medical school in Denver, Colorado and completing her Internal Medicine residency in Long Beach, California. Her love of medicine developed into a love for aesthetics but also for preventive medicine and she began exploring options in more natural ways to heal the body and make her patients feel healthy and also beautiful from the inside and out.
She met her best friend Dina during her medical school training and dreamed for years about plans to expand their passion and knowledge before finally opening up me.losangeles aesthetics in 2019 to pursue their mutual goal. To date, she’s still very excited to continue the pursuit of preventive medicine offering services at the spa such as IV and vitamin infusions but with a touch of aesthetics to help her patients look and feel their best.
She’s always exploring ways to grow the spa in such a way to incorporate these ideas and be the best doctor she can be to all of her patients.
