Dr. Ritika Sharma

Dr. Ritika Sharma is the owner and lead dentist at Crown Isle Dental. She takes time to understand your concerns and explain the choices available to you.

Her calm, gentle approach helps patients who feel anxious about dental visits. She explains each step and works with you to make treatment more comfortable.

Earning her degree from the University of Colorado, Dr. Sharma practices conservative and evidence-based dentistry. She takes the time to listen to your concerns, explain your options clearly, and ensure you feel completely in control of your care.

A proud member of the Comox Valley community, her nurturing spirit extends far beyond the clinic doors. When she is not caring for her patients' smiles, she is usually out exploring Vancouver Island trails with her husband and their seven-year-old son, cultivating her garden, or bringing her creativity to life through artistic home improvement projects.

Dr. Colleen Greiner

Dr. Colleen received her Doctor of Dental Medicine degree in 1988 from the University of Manitoba, completed a short service engagement with the Canadian Armed Forces, and has been happily practicing family dentistry in the Comox Valley since 1991. Known for many years as Dr. Colleen Clancy, she recently returned to her maiden name, Greiner. At Crown Isle Dental we refer to her simply as Dr. Colleen.

With a wealth of experience, Dr. Colleen is passionate about ongoing learning, particularly patient comfort, quality long-term outcomes, and occlusion as it relates to the TMJ. She takes great care in making treatment plans easily understandable for every patient.

Outside the clinic, Colleen loves the outdoor beauty of the Comox Valley and the small community feel. Her hobbies include skiing, sea kayaking, and gardening throughout the Valley.

Our philosophy

What we believe about dentistry.

Ethical, not procedure-driven

We explain why treatment is recommended, what alternatives are available, and what each option involves.

Stability and continuity

Dr. Sharma and Dr. Greiner get to know your dental history and help you plan ongoing care.

Evidence-based care

Every recommendation is grounded in current clinical evidence. We explain the why behind every treatment so you can make an informed decision.

Safety first

Mercury-free and BPA-free fillings since 1996. We have always prioritized the materials and protocols that protect you and your family.

Modern technology

Pearl AI radiograph analysis, digital X-rays, intraoral scanner, in-house 3D printer, and a fully paperless office - technology that improves your care, not just our marketing.

Rooted in the Valley

Since 1996, we've cared for families across generations in Courtenay and the Comox Valley. We're your neighbours, invested in this community for the long term.
