Collaborative Experts, United for Your Care

Affiliated Providers

We work collaboratively with all referring providers as well as with a curated network of affiliated providers — experts in areas like pelvic floor therapy, pain management and gastroenterology — who are not part of Steven Vasilev MD Professional Corporation— but who extend availability of the layers of integrative care we recommend as part of holistic comprehensive endometriosis management. While our in-house team sets the foundation, affiliated specialists bring focused expertise in their respective fields so that no aspect of your health goes unexamined. This collaboration ensures that when the time comes to move toward diagnosis, treatment, or ongoing support, you benefit from a truly holistic, multidisciplinary approach. We share our list with you when you become our patient. Regarding Pelvic Floor PT, the iCareBetter link offers many options close to you.
