Welcome to the Lotus Endometriosis Institute
Advanced Care, Human Touch

Founded and led by world-renowned surgeon Dr. Steven Vasilev, our team specializes in advanced robotic excision and integrative support that offers real, lasting results—especially for the most complex cases. Every patient is more than a diagnosis, and our mission is to provide precision treatment while supporting the whole person—mind, body, and spirit. Here, innovation and empathy work hand in hand to help you reclaim your health and your future.
Defining the Next Level of Care
The Lotus Difference
The Lotus Endometriosis Institute (LEI) is more than a center of care — it’s a promise of possibility, offering hope, healing, and a new standard in endometriosis treatment. At its helm is Dr. Steve Vasilev, founder, director, and head surgeon. With decades of surgical mastery, deep integrative insight, and a passion for patient-centered research and innovation, he leads LEI in reshaping what is possible for those suffering with endo.
The Only Quadruple-Board-Certified Endometriosis Surgeon in the U.S.
Dr. Steve Vasilev holds an unmatched distinction as the only physician in the United States to hold board certification in Gynecology, Gynecologic Oncology, Integrative Medicine, and Holistic Medicine, with advanced expertise in robotic surgery. This rare combination ensures every patient receives care that integrates the highest level of surgical precision, evidence-based medical management, and whole-person healing. At our institute, integrative medicine is not just a catchphrase—it is where advanced science and holistic principles genuinely meet.
Only at Lotus: Surgical Training & Experience at the Highest Level
Most excision specialists pursue advanced minimally invasive fellowships, with varying degrees of focus on endometriosis and complex pelvic surgery. Dr. Vasilev, however, trained in an ACGME-accredited fellowship in Gynecologic Oncology—a far more rigorous program than the variable MIGS fellowships typically available. His training provides unmatched skill and full hospital privileges for all pelvic and intra-abdominal surgeries, including those involving the bowel, bladder, diaphragm, liver, spleen, and ureters. Beyond this, his 30+ years of surgical experience further solidify his standing at the highest possible level.
The Only Gynecologic Oncologist Focused on Endometriosis & Adenomyosis
While gynecologic oncologists sporadically assist with difficult endometriosis cases, a broad range of gynecologic cancers is their focus. Dr. Vasilev stands alone as the only gynecologic oncologist in the U.S. solely dedicated to endometriosis, adenomyosis and related tumors and cancers. His patients benefit from highest-level abdominal and pelvic surgical training applied to a disease frequently underestimated by imaging before surgery.
"Dr. Vasilev and his team are incredible. I live in Iowa, and they worked with me long distance via zoom to discuss my condition and surgery. My disease, endometriosis, was chronic and had spread to almost my entire abdominal cavity and organs. Dr. Vasilev was able to clear out all the endometriosis, adhesions, and fibrosis. I trust him with my life."
Science-Driven, Patient-Focused
Our Approach
We go beyond simply treating endometriosis—we care for the whole person. By merging innovation with integrative approaches and pairing medical expertise with personal guidance, we create a path to healing that is both advanced and compassionate.
Evaluation & Diagnosis
Answers begin with understanding.
We start by listening—really listening—to your story and symptoms. Our diagnostic process is designed to uncover the true cause of your pain or fertility challenges, including conditions that are often overlooked elsewhere. Every treatment journey begins with clarity.
Surgery & Advanced Excision
Precision that changes lives.
Led by Dr. Steven Vasilev, one of the world’s foremost experts in robotic excision, our surgical care focuses on complete removal of disease with minimal trauma. Using advanced robotic 3-D visualization and microsurgical precision, we aim for lasting relief—not temporary fixes.
Integrative & Lifestyle Care
Healing beyond surgery.
True recovery involves more than the operating room. We combine evidence-based integrative medicine, nutrition, hormonal balance, and mind-body support to help you heal fully and prevent recurrence. It’s comprehensive, personalized care for long-term wellness.
