Meet Our Team

Dr. Kirsten Ness

Dr. Ness graduated in 1991 from the Ontario Veterinary College at the University of Guelph in the honours program. The plan was always to practice large animal medicine. However, after graduation, Dr. Ness started working at a small animal clinic in the Kingston area and has never looked back!

Upon moving to St. Catharines in 1993, Dr. Ness practiced at local small animal clinics, and at a local emergency clinic, before purchasing Glenridge Animal Hospital (GAH) in 2010.

Since owning GAH, Dr. Ness has acted as a referral surgeon for other clinics, as her passion lies in the surgery room.

She also regularly takes continuing education classes to keep up to date with all the changes in the veterinary field.

When she is not at the clinic, she is either curled up with all her kitties and her dog, Sheldon, or traveling the globe, as her second passion is traveling.

Dr. Lisa Van Lammers

Dr. Lisa Van Lammers graduated alongside Dr. Ness in 1991 from the Ontario Veterinary College, University of Guelph in the Honours program. She started practising small animal medicine in Toronto until she married and moved to the Niagara Region in 1995.

After working for a few years at small animal clinics in the Niagara region, Dr. Van Lammers made the decision to open the NOTL Veterinary House Call Service which she operated while working at GAH. Although the house call business is no longer operating, Dr. Van Lammers is still a loved member of the Glenridge team.

When she is not working, Dr. Van Lammers enjoys spending time with her husband and 2 sons along with their small herd of dogs - Dorris, Owen, Tini, Max and Grady. She also takes several continuing education classes to keep up-to-date on all the changes in the veterinarian field, and in her rare off hours, she enjoys reading and gardening.

Dr. Rachel Monjos

Dr. Rachel Manjos was born in Hamilton, ON and raised in the town of Lincoln. Her love of nature, wildlife and pets led to her decision to pursue a career in veterinary medicine. Prior to veterinary school, she spent summers at The Owl Foundation in Vineland learning the care and treatment of various owl species.

After completing a Bachelor of Science in biological sciences at the University of Guelph, she graduated with a Doctor of Veterinary Medicine from the Ontario Veterinary College in 2017. Since graduation, Dr. Rachel has developed special interests in the fields of ophthalmology, soft tissue surgery and the treatment of some exotic animal species. She enjoys providing quality care to pets and forming lasting bonds with their owners.

Outside of practice, Dr. Rachel enjoys going to the gym, watching movies and taking care of many plants. She shares her home with two cats and two rabbits, who weigh around 2 pounds each!

Amanda started her career in the veterinary field in Grade 9 as a co-op student and has continued in the field ever since. While working, she completed the Paralegal program at TriOS College with honours, but her love for animals kept her from pursuing a career in the legal field. Amanda worked at the Fort Erie Racetrack as a hot-walker and groomer, and for many years at our local emergency clinic before finding her place at GAH.

Amanda and her spouse share their home with their dogs – Marshall and Peggy, their rabbit – Roy Douglas, their cat – Vladimir, and their fish. Amanda spends her evenings caring for several horses at a boarding facility, including her own horse Tex. 

In her spare time she enjoys reading, running, yoga, and spending time with her family.



Alison graduated from the University of Guelph as a Registered Veterinary Technician in 2001. Over the years, she has worked in various small animal clinics in the Hamilton and Niagara regions, including our local emergency clinic for 6 years. She became part of the Glenridge family in 2019.

Travelling the world to help animals in need is something that is very dear to Alison. She has been part of several Street Dog Spay and Neuter Projects in places like Squamish BC, Sri Lanka and Guatemala. During her stint in Guatemala, she fell in love with a street dog they named Skittles. So much so that she brought him home and they spent 16 wonderful years together. Her passion for animals carries into nature and the proper care and rehabilitation of wildlife here and afar, including time volunteering at the Olive Ridley Sea Turtle Conservation in Costa Rica. 

Alison is also a part time photographer. She takes amazing photos of nature, pets and their families. When not at the clinic or out on a shoot, she enjoys spending time with her husband and son.



After finishing high school, Matt attended the University of Western Ontario where he graduated with a 3 year BA before heading off to work for Disney! After Disney, he moved around and tried out some different jobs before his love of animals sent him to St Lawrence College. Here, he graduated from the Veterinary Technician course in 2014 and then landed back in St. Catharines.

After graduation, he spent 5 years working at the Bird Kingdom in Niagara Falls, as well as some time at other local clinics before landing a spot in the Glenridge family. 

In his spare time, Matt enjoys outdoor life. Spending time with his wife and their dog, Cricket, you can find them camping and fishing.



Morgan didn’t know right away that her passion was going to lead her to the veterinary world. After spending 10 years working in customer service, she became a nanny to two wonderful children in Ottawa. Once ending up in the Niagara region, she began working at an ice cream shop in NOTL.

While here, she became the owner of some very lovely rats. The love of her rats is what turned her passion for animals into full force and she decided to go back to school. After attending the University of Guelph and graduating with a certificate in Veterinary Office Administration and Assistance, she became a member of the Glenridge family. 

When not at work, Morgan loves to travel and visit her family across Ontario. Other talents include baking/cooking and painting abstract art or dot paint rocks. She also enjoys exploring the many wineries in the area.

Sheri shares her home with her three wonderful children and her equally wonderful cats! In her spare time, she enjoys spending time with her family and working out.



Andrea graduated from St Clair College of Applied Arts and Technology in 2008 as a Registered Veterinary Technician. Meeting and working with Dr. Ness at a mixed animal clinic, she was asked to make the leap and come to Glenridge Animal Hospital when Dr. Ness purchased it in 2010. Andrea quickly became a valued member of the family. After taking a brief detour to explore other options, Andrea has returned home where she belongs!

Andrea has a great interest in Canine Behaviour and Communication and has taken courses to further her knowledge in this field. In addition, she has Business and Accounting courses under her belt. 

Yoga, meditation, and hiking fill a lot of Andrea’s spare time. Along with time with family and friends and her furry kids – Gus and Turbo.
