Esthetician
Valerie has been a long-time patient of W Dermatology—over 15 years—which makes joining the team especially meaningful to her. Her personal skincare journey began during her time as a professional cheerleader for both the NBA and NFL, where maintaining healthy, radiant skin was essential under the spotlight. That experience inspired her to pursue a career dedicated to helping others achieve confidence through healthy skin.
Before joining W Dermatology, Valerie gained extensive hands-on experience working at several medical spas across Newport Beach and Los Angeles, where she focused her techniques in both corrective and maintenance skincare. She treats a variety of skin concerns including acne, acne scarring, and hyperpigmentation, and offers advanced treatments such as dermaplaning, acne extractions, chemical peels, light therapy, and customized facial masks.
Valerie takes pride in caring for her patients’ skin with the same dedication she gives her own. She is passionate about educating patients, helping them build effective skincare routines, and celebrating their progress every step of the way.
Valerie is thrilled to be part of the W Dermatology team and to continue serving patients with compassion, expertise, and genuine care.
