About Dellay Aging
Meet Amanda
Amanda Dellay is a board-certified Nurse Practitioner who recently earned her Master of Science in Nursing as an Adult-Gerontology Primary Care Nurse Practitioner from Walden University. Her journey into medicine started long before that — Amanda is an eight-year Army Veteran who went on to graduate from Saint Louis Community College – Meramec as a Registered Nurse, building her clinical foundation in emergency room, pediatric and trauma care, and the operating room.
That combination — military discipline, ER-trained instincts, and primary care expertise — is what shapes the way Amanda practices today. She looks beyond the surface to understand how every system in the body contributes to the way you look, feel, and age.
Amanda founded Dellay Aging because she saw too many patients chasing cosmetic results without ever addressing the health that produces them. Beautiful skin, lasting energy, and graceful aging don’t happen in isolation — they begin with what’s happening inside your body.
She prides herself on her empathetic approach, listening closely to each client’s needs and goals. Her philosophy emphasizes natural rejuvenation: results that don’t change the way you look, but keep you looking younger and feeling better about yourself, inside and out.
Our Mission
To help every patient age with confidence, vitality, and authenticity by treating the whole person — not just the reflection. We believe true beauty is the visible expression of internal health, and our role is to help you cultivate both.
What Makes Us Different
We are not a quick-fix injection clinic. Dellay Aging is led by a primary care–trained Nurse Practitioner, which means every aesthetic treatment is informed by a deep understanding of physiology, hormones, and long-term wellness. We take time to understand your full health picture before recommending a plan, and we build customized protocols that combine internal and external care for results you can actually sustain.
You won’t find a one-size-fits-all menu here. You’ll find a clinician who listens, a plan built specifically for you, and a team committed to your long-term outcomes — not just your next appointment.
Why Patients Need Us
Aging is not a problem to fix; it’s a process to support. Most patients come to us frustrated after years of treatments that never quite delivered, or after being handed cosmetic recommendations without anyone asking how they actually feel. They need a provider who can connect the dots — between sleep, stress, hormones, nutrition, skin health, and the way they show up in the world.
That’s what we do at Dellay Aging. We give you a single, expert place to address every layer of how you age, so you can stop piecing together your wellness from a dozen different providers and finally see — and feel — the results you’ve been working toward.
Outside the Clinic
Amanda is married to her husband Brent, a disabled military veteran, and is the proud mom of two young adults who graduated from Eureka High School. When she isn’t with patients, you’ll find her on the family farm tending to their goats and chickens — proof that the slower, more grounded life she helps her patients pursue is one she lives herself.
