Following his hospital experience, Dr Tass established Dr Tass Cosmetic and Skin Clinics, with locations across Melbourne including Crown Melbourne, the heritage-listed former Port Melbourne railway station, and a heritage-listed Ripponlea building. At these clinics, he consults with patients regarding non-surgical aesthetic services, skin-focused treatments, and device-based procedures, guided by individual assessment and medical suitability.

In addition to his clinical work, Dr Tass has developed a cosmeceutical skincare range of professionally formulated products for general skin care and maintenance. He is also the founder of the Dr Tass Hair Program, a structured program for men and women experiencing hair-related concerns. A comprehensive medical consultation and assessment is required before participation in the program.

Throughout his career, Dr Tass has participated in professional education and advisory activities within the field of aesthetic medicine and has collaborated with companies and professional groups, both nationally and internationally. His approach to practice emphasises careful planning and consideration of individual facial structure, including proportion and balance, rather than standardised treatment approaches.

Outside of medicine, Dr Tass maintains a long-standing interest in art, architecture, and fashion, regularly visiting galleries, museums, and international cultural events. He believes that exposure to the creative disciplines of art and design contributes to his appreciation of form, symmetry, and visual harmony, which also informs his approach to facial aesthetics. This perspective influences both his personal outlook and his professional work, where clinical knowledge is combined with an understanding of proportion and structure.

At Dr Tass Cosmetic and Skin Clinics, the focus remains on providing a professional, considered environment where patients are supported through informed consultation, appropriate treatment planning, and ongoing medical care.
