About our Optometrists and Optical Technicians

Dr. Annette DelioDr. Annette Delio moved to Canada in 1995 and became a licensed optometrist in Ontario in 1996. Before her move north, she graduated from Indiana University with her Associate of Science Optometry (1980), Bachelor of Science of Optometry (1986) and Doctor of Optometry in (1988). She practiced with her father Dr. R. W. Zehner in Evansville, Indiana for 7 years, until love pulled her away from the family practice, which was started by her grandmother, Dr. Meta Zehner in 1935.

She began her Canadian career working next to Optical outlets in Caledonia and Hamilton before she opened her own private practice in 2004 in the West Haldimand General Hospital.

She’s a member of the Ontario Association of Optometrists, Canadian Association of Optometrists as well as the Chamber of Commerce.  Annette is as involved in her community as much as she is in her career.

As a participant of the ESEL program (Eye See Eye Learn), Annette provides eye exams to junior kindergarten students in her regional school zone. This is a brand new program to Haldimand County.  Examinations are provided by Dr. Delio, via OHIP, and glasses are provided free of charge to the patient.  This program is only available to children entering junior kindergarten beginning in the fall of 2013.

When she’s not poking and prodding your eyes, Annette spends her time with her step kids Kevin and Victoria, her twin Grandsons born February 2017, and her husband Mark (who you might notice from the photos) watching movies, gardening, reading, travelling, and lately weight lifting with Carrie Misener of Evolution Physique and Fitness.  Oh and she also has a crazy cats Ozzie who thinks he’s the boss.

She also would like to thank her Brantford patients for allowing her to care for their visual needs and eye health and would love to see their friendly faces if they’re ever in Caledonia!

Sue Armstrong

Sue Armstrong started her career with Dr. Delio in 2004 as her Optometric Technician, but she jokingly says she’s the boss. Sue, shares the responsibilities of working with the patients to help choose frames, ordering, verifying spectacle prescription, dispensing, adjusting and repairing eyewear and the everyday joys of working for the wonderful Dr. Annette Delio. Sue also manages the frame inventory, and accounts payable.

When not working, Sue can be found entertaining in her kitchen, reading, or throwing parties. As a lover of recipes and sharing kitchen secrets, she has quite the excuse to cook with four kids to feed. Sue moved to Cayuga from Sudbury for true love in 1986 and then to their farm in 1991. She loves farm life, but admits she’s not much of a farm wife so she lets her husband tend to their cattle and cash crops; but she’s still a loving wife and will shut the gate if he happens to leave it open.

Carol Fearman

Carol Fearman has been Dr. Annette Delio’s receptionist since 2005. On top of making Annette’s life easy around the office, Carol runs a tight fiscal watch on all expenses- it’s a joke around the office, but she makes sure every pencil is worked down to the stub before a new one is bought. Carol is also our primary pre-test technician, and manages the contact lens and eyewear accessory inventories.

Carol was born and raised in Halidmand County and has raised her two children here too. Before working for Dr. Delio she helped run a catering business with her sister, and worked at Hagersville Foodland for 6 years.  Now residing on 36 acres she spends her time watching scary movies and reading Stephen King novels.

Tracy Neil

Tracy Neill  comes to us from Cayuga where she has lived for the past 20 years. Tracy was lucky enough to be able to stay at home and raise her two children. When her husband was injured at work, Tracy was forced to look for work outside the home. The local grocery store/garden centre would be her calling for the next 9 years.

Tracy has a passion for helping people and enjoys volunteering. When her children were in school, she volunteered in every capacity; Family is everything! Tracy has been a trustee on the Board at Cottonwood mansion for the past two years. Although her term is up soon, she will still be available to lend a helping hand when needed. When she’s got some down time, Tracy loves to hang out with family and friends. Smiling is a huge part of her life as well. It only takes 17 muscles to smile; 42 to frown. It’s a no brainer!
