Dr. Bloom and her wife underwent infertility treatment for over a year before successfully conceiving with IVF and welcoming twin boys into their family.

“Our personal journey to motherhood has allowed me to better understand the emotional and physical toll infertility treatments can have on my patients and their partners.”
