“Trish has an amazing way of providing comfort and hope in a time of frustration and confusion, all while dealing with the whirlwind of post-delivery hormones.  I seriously cannot say enough positive things about this woman, and I am so blessed to have had the privilege to work with her.”

“Trish's extensive knowledge and suportive presence made all the difference in my breastfeeding relationship with my daughter.  We struggled a lot and without Trish's help, I know our breastfeeding relationship would not have been the success it was.  Tish is the first person I turn to if I need breastfeeding support and the first person I recommend to my friends.”
Shannon W, Peoria, IL.
