Dr Rohani moved with his family from Iran to New Zealand in 1997. After completing his high school education in Dunedin, Dr Rohani attended Otago University where he graduated with a Bachelor of Dental Surgery. He later passed the National Board Dental Examination I and II in USA and returned to New Zealand to practice dentistry.

Dr Rohani initially worked in the public sector in Auckland, providing his services to the Oral-Maxillo Facial Unit at Greenlane and Middlemore hospitals. He became accomplished in hospital dentistry, oral surgery, oral medicine and emergency dentistry, and also attended to patients with special needs, including those with heart, kidney or liver conditions.

These experiences stood him in good stead for working in the private sector. Following three years in private practice in Auckland, Dr Rohani moved to Hamilton and became the proud owner of Relax Dental in 2008. Eleven years on, and keen to serve the needs of people in the city's south-east, he opened Happy Dental in Glenview.

Dr Rohani's personal approach to dentistry priorities these essential elements:

• High quality and conservative treatments: All measures are taken to carry out treatment that meets the highest standards of professional dentistry.
• Providing a caring and low-stress environment: Every effort is made to care for individual patients and minimise their stress as much as possible.
• Retention: Doing the utmost to ensure all oral tissues remain intact, and in good shape and health. Good dentistry is about oral tissue, including bone, gingivae, teeth, salivary glands, muscles, nerves and the temperomandibular joint (TMJ). While each of these has its own specific function, they are designed to work in harmony. If one becomes compromised, then the rest may be damaged.
• Prevention: Placing a strong emphasis on prevention to maintain a lifelong healthy mouth and smile.
