Dr. Steven Williams

Founder & Lead Plastic Surgeon

Steven Williams, MD is a board certified Oakland plastic surgeon at Tri Valley Plastic Surgery. He leads the Tri Valley Plastic Surgery team providing outstanding cosmetic and reconstructive plastic surgery. His education and training has exclusively been at ivy league institutions (Dartmouth for college, Yale University for medical school and residency training).

He specializes in cosmetic face, body and breast work. At Tri Valley Plastic Surgery we are one of the busiest practices for breast augmentation and are the leaders in body contouring with techniques like minimal pain tummy tucks and fat transfer to enhance patient curves including hips, buttocks and breasts.

Dr. Steven Williams is a passionate plastic surgery professional with a decade of hands-on expertise in cosmetic and reconstructive surgery. He occupies leadership roles at the local, state and national level and is frequently sought for his expertise. Not only is he involved with individualized patient care, but he is also a pioneer in the greater agendas of the plastic surgery realm – even lobbying in Washington, DC for insurance rights for breast cancer survivors.

Masha Chebotarev Registered Nurse

Masha Chebotarev is a Registered Nurse focusing on Aesthetics and has a background in hospital administration.

Masha grew up in Walnut Creek after immigrating from Moscow, Russia, and has lived in the bay area since. Masha's interest in medicine started during her pre-professional ballet career, where she was highly involved in sports medicine and physical therapy programs. Masha is currently pursuing her Master's in Nursing in Hospital Administration and Management.

Masha is passionate about wellness and all-things skincare. She struggled with cystic acne for over ten years - trying various products through trial and error. When her medicine cabinet was overflowing, Masha decided to take a different route. She stopped trying the trends, stopped listening to the influencers, and relied on evidence-based research. The results spoke for themselves. Masha found herself using fewer products, spending less money, and using less of her precious time. And most importantly, she found her confidence.

With this experience behind her and her education supporting her, Masha strives to provide a comprehensive, attainable plan to get her patients exactly where they want to be, putting their best face forward!
