The Lotus Approach
The Lotus Endometriosis Institute provides care across the full spectrum—from early diagnosis to advanced multidisciplinary excision surgery. We combine advanced robotic excision surgery with comprehensive integrative support—nutrition, hormonal optimization, microbiome balance, stress and neuro-immune-endocrine axis modulation —to help optimize recovery.
Every plan is personal. There’s a reason patients come to California.

“I trust Dr. Vasilev with my life
I live in Iowa, and they worked with me long distance via zoom to discuss my condition and surgery. Dr. Vasilev has an insurance team who worked with my insurance to reduce my financial burden, and they succeeded! This surgery is life changing for those of us who suffer everyday with chronic symptoms."
