Reuben W. Holland III, MD, FACEP
Medical Director
- Board-certified emergency physician
- More than 35 years of clinical, academic and leadership experience
- FACEP: Fellow of the American College of Emergency Physicians
Dr. Holland’s role supports our clinical protocols, safety standards, medical escalation pathways, regulatory alignment and medically responsible treatment planning.
His emergency medicine background brings a strong foundation in risk assessment, clinical judgment, safety and systems-based care. That oversight matters in a med spa. Injectables, lasers, prescription wellness programs, hormone care, medical weight loss and IV therapy all need careful screening, documentation, candidacy review and provider accountability.

What we will not do.
Trust is built by what a medical practice refuses to do. Restraint is part of our standard.
No pressure
We will not pressure you into treatment or rush a decision when a consultation, education or more time is the better first step.
No trend-chasing
We will not recommend a service because it is popular or heavily promoted if it does not fit your anatomy, goals, timing or candidacy.
No overcorrection
We will not chase an overfilled or overtreated look that ignores your features, movement, proportions and long-term plan.
No ignoring safety
We will not ignore medical history, medications, pregnancy or breastfeeding, prior treatments, downtime or provider concerns. Sometimes the right answer is to wait.
