A private aesthetic practice in Arcadia, dedicated to medical expertise, clinical precision, and natural elegance.
Med 44 Arcadia was founded by Holly Mueller, Cosmetic Nurse and Medical Aesthetician, with a singular vision: to offer Phoenix's most discerning patients a private, luxury aesthetic experience built on science, artistry, and genuine care.
Named for our address at 4750 N 44th Street, Med 44 has grown into one of the most trusted and referred aesthetic practices in the Phoenix Valley. We welcome patients from Arcadia, Scottsdale, Paradise Valley, and the greater Phoenix area, alongside many traveling clients who visit specifically for our clinical expertise.
Our clinical team includes Nurse Practitioners, Registered Nurses, and Licensed Aestheticians, united by rigorous training in facial anatomy, advanced modalities, and an uncompromising commitment to patient comfort.
Four principles that guide every consultation, every treatment, and every patient relationship at Med 44 Arcadia.
01
We don't believe in one-size-fits-all aesthetics. Every patient receives a thorough consultation and a fully personalized plan based on their unique anatomy, skin type, lifestyle, and long-term goals. Your treatment plan evolves with you.
02
We examine the cellular and anatomical factors behind skin changes and volume loss. Every protocol is evidence-based and designed to build structural integrity and skin vitality for sustainable, lasting improvement.
03
Radiant skin is the cornerstone of lasting confidence. We help patients establish focused regimens through medical-grade skincare, targeted clinic therapies, and daily protective habits that deliver visible results over time.
04
The finest aesthetic work is subtle, harmonious, and imperceptible. Our clinical focus is for every patient to appear rested, beautifully contoured, and naturally vibrant, preserving personal character without exaggeration.
Led by founder Holly Mueller, our team combines medical expertise, artistic precision, and a deep commitment to patient care.
