Dr Sean Crookes

Co-founding Dentist

Dr Sean Crookes graduated from the University of Queensland in 1993 with a Bachelor of Dental Science. Sean has worked in both Australia and the United Kingdom, gaining valuable experience working in private dental practices. During this period, he spent much of his time planning his ideal practice.

Sean and his wife, Nicolie, returned to Australia with the vision of opening a modern dental practice that offers first class service, and in 2002, he realised this dream when they opened the doors to Crookes & Jenkins Dental.

Sean is dedicated to his patients’ oral health care needs and spends quality time with all of his patients to explain treatments and procedures and share the passion of his work. He enjoys educating people on the many areas of oral health and relishes in the positive feedback and wonderful results he experiences every day.

Sean regularly updates his skills by attending numerous continuing education courses throughout the year and is also a member of a dental study group where he has previously held the role of President. He is also actively involved with a number of charities and associations giving time and resources to help enrich our local community and help those less fortunate who live overseas. He is a father and family man and loves sharing time with his wife and son.

In his spare time, Sean enjoys maintaining his garden, honing his skills in art and sculpture, bushwalking, fly fishing and taking long walks with his Bull Mastiff X Buster.

Dr Nicolie Jenkins

Co-founding Dentist

Dr Nicolie Jenkins was born in Brisbane and spent her adolescent years in Moranbah in North Queensland with her family.

Nicki returned to Brisbane to study at the University of Queensland and in 1993, graduated with a Bachelor of Dental Science.

Nicki’s experience enables Crookes and Jenkins Dental to be a practice which provides patients with a personal and friendly service. Working with Sean to provide a dental practice that is both relaxing and modern, they believe that their patients should be treated as they would wish to be treated themselves.

Nicki has a relaxed and calming persona, which all of her patients love, and her gentleness is carried through to her work. She instantly puts her patients at ease and in fact many fall asleep in the chair! Nicki also attends continuing education courses on offer throughout the year.

Nicki is the proud mother of her son Micael, who was born in May 2008. She is passionate about singing in her spare time and enjoys performing with two local choirs and the many concerts put on throughout the year.
