At Unicorn Medical Weight Loss, our name is more than just memorable — it’s rooted in purpose. U.N.I.C.O.R.N. stands for United Consulting & Research Network Inc., reflecting our long-standing commitment to evidence-based, personalized care.
Founded in 1993 by Dr. Charles McMenamy, Unicorn has built a legacy on integrity, accountability, and results. From the beginning, Dr. McMenamy took a hands-on approach with both patients and staff, ensuring that every element of our weight loss programs reflected the highest standards of care. Rather than following a one-size-fits-all, sales-driven model, Unicorn has always prioritized people over profit — focusing first on integrating patients into a supportive, structured program before discussing products or services.
What makes us different? It’s our unwavering commitment to:
Personalized attention and real relationships — not a transactional experience
Thoughtful, in-depth counseling to uncover root causes and support long-term change
Regular, educational diet classes to empower your understanding of nutrition and wellness
