Dr. Marcus started her practice as Assistant Professor and General Practitioner in a fast pace urban university clinic, dealing with acute illnesses and injuries while teaching pathology and toxicology to medical students. A field concentrating mainly on the physical aspects of the human body and the treatment of its ailments.

Her passion has always been to have an ongoing relationship with her patients as she directs them towards achieving a sense of well-being and satisfaction. She then has directed her career towards an in-depth understanding, and deciphering human feelings and behavior.

During the course of completing two Board Certifications, different research studies, and an involved practice with her clients, Dr. Marcus observed the connection between one's perception of their physical look and their love of their inner self. Those who like themselves work on maintaining and caring for their body, and those who maintain a healthy beautiful physique feel much better about their persona.

That was the force behind her seeking advanced training and board certification in aesthetic medicine. In 2005 Dr. Abir Marcus founded BiroVenus Medical Spa. She is personally directing and performing advanced non-invasive aesthetic treatments and procedures. BiroVenus Medical Spa, rejuvenation and wellness center is the source for men and women to experience the empowerment of actively pursuing their physical and emotional well-being, and enjoying each stage of their life's journey.
