Customers Say
“I feel so empowered and encouraged after my consultation with Erin! As someone with endometriosis, medical appointments often leave me feeling dismissed and disillusioned, however with Erin, I felt listened to, heard, and left feeling confident that we had a plan in place and that things could get better for me.
Through her advice and recommendations I have already seen an improvement in my sleep, my fatigue, and my mood. I have also seen a decrease in my endometriosis symptoms including a reduction in my pain levels. I feel like a new person already and it's just early days from the initial consult.
Highly recommend Erin!.”
