Ilex Eye: Eye Doctors in Waterloo
  • Who We Are
  • Staff


Our staff are friendly, helpful and ready to assist you. They participate regularly in continuing education programs to better equip them to look after your eye care needs. 



Crystal joined Ilex Eye Associates in 2014, has completed the Canadian Association of Optometrists Certified Optometric Assistants Program, and is our Administrative Manager. She is usually the first face you'll see at reception, but you may also find her performing your special testing or helping you find the perfect pair of glasses.  In her spare time, Crystal enjoys hanging out with her husband and her two beautiful dogs, reading, playing games, or driving through the country taking photographs (often of cows).




Avery has been a part of the Ilex team since 2015. She holds a diploma in Medical Office Administration, is currently studying to become an optician, and manages the optical side of Ilex. You'll often hear her voice on the phone, and will find her helping in the dispensary, or performing special testing and ophthalmic imaging. Outside the office, Avery loves sitting at a piano, reading a novel, or exploring outdoors with her husband, two daughters, and St. Bernard, Rosie.





Ashley joined Ilex Eye Associates in early 2019. After ten years as a hairstylist she decided it was time for a change, and headed back to Conestoga College. You'll find her smiling face at our reception desk, and performing special testing including photography, imaging, and visual field testing. Ashley spends her free time with her husband and two daughters watching movies, playing games, camping, and hiking.





Manpreet joined Ilex Eye Associates in mid-2020 after graduating from the Conestoga College Medical Office Administration Program. Born in India, she speaks English, Punjabi, and Hindi, and has quickly become a critical team member, greeting patients at reception, assisting with frame selections and repairs, and performing special testing. In her spare time, Manpreet enjoys cooking and watching movies.






Shannon came aboard in spring 2021 after fifteen years in customer service. She has hit the ground running, and you'll likely meet her during your visit at reception, during special testing, or as you pick out your new glasses ... or all three. When she's not at Ilex, Shannon enjoys spending time outdoors and with her family, where she is outnumbered by boys (including the dog).





Melissa joined the Ilex team in late summer 2021. She is quickly learning the ropes in administration, dispensing, and special testing. During her free time, she enjoys taking walks with her two daughters, dancing like no one is watching, and singing to her heart's content. You will often find her taking photos of anything related to nature, especially animals.

Esther is the newest addition to our practice, beginning work in mid-2022 following an internship. When she is not at Ilex, she likes to spend time with her friends and family, and you will often find her at the church she is involved in. Esther enjoys reading and photography, and her camera roll is full of sunrise and sunset pictures.
