Jen Tietjen

Pediatric Nurse Practitioner, Certified Lactation Counselor, Founder of Your Village STL

Hi! My name is Jen and I’m a mom to two beautiful little girls who continue to teach me valuable lessons daily! They both have some special needs that keep me on my toes. I became passionate about serving families in the early years of parenting during my own struggles with breastfeeding, postpartum anxiety and childhood sleep difficulties. As a result, I have so much empathy for families navigating these difficult years. When I’m not working, I enjoy spending time outdoors with my girls, anything animal related (zoo, Grant’s Farm, Gentle Barn), yoga, playing with my cat and dog, and traveling.

I completed my undergraduate degree in Nursing at Valparaiso University and went on to start my nursing career in the Pediatric Intensive Care Unit at Mercy Children’s in St. Louis. I then completed my Master’s of Science in Nursing at Saint Louis University to become a Pediatric Nurse Practitioner (PNP). I began my career as a PNP working at Mercy Children’s in Kansas City in their Pediatric Sleep Clinic. After moving back to St. Louis, I worked several years in Pediatric Primary Care. I have also completed additional education, becoming a Certified Lactation Counselor, a Certified Gentle Sleep Coach and being certified in Perinatal Mental health. I consider the whole child and family system when making recommendations. I always start by really taking the time to sit down and LISTEN to your story!

I will encourage you to listen to your intuition because you know what is right for you and your family!
