Dr. Derek Nichols, Veterinarian, DVM

Education: Ontario Veterinary College

New Owner as of January 1st, 2022


Dr. Derek Nichols was born and raised in St. Catharines. He has an undergraduate degree in Zoology from the University of Guelph and graduated from the Ontario Veterinary College in 2011. Dr. Derek returned to the Niagara region after graduation, where he has been practicing ever since. 

He is a dedicated and passionate professional who loves surgery and assisting his furry friends while they are under his exceptional care. Building genuine and trusting relationships with his patients and their families is Dr. Derek’s number one priority. Additionally, he prioritizes continuing education in order to stay current on the most up-to-date medical practices and treatments. 

Dr. Derek resides in the town of Virgil with his wife, Stephanie and their three boys, three cats, and two dogs. In his spare time, he can usually be found at the rink helping coach his sons’ hockey teams. He also enjoys playing hockey with his friends, waterskiing and relaxing by the lake in cottage country with his family.

In Honour of the Founder of Virgil Animal Hospital:

Dr. Ron Mergl, Veterinarian, BSc, DVM, MSc

Hometown: Niagara-On-The-Lake

Dr. Ron Mergl had the idea to build a new hospital in Virgil and spent two years looking for the right site. Then, he and his wife, Dr. June Mergl, spent another two years building it and filling it with top-of-the-line equipment and staff to best serve the needs of the pets that were to walk through the doors. The result was a stunning new veterinary hospital that took off rapidly. Dr. Ron was very excited when Virgil Animal Hospital opened in November of 2019 and was looking forward to many years of service to the pets of Niagara.

Unfortunately, that was not to be. Sadly, Dr. Ron passed away in 2020 from a brain tumour. Born in Niagara, Dr. Ron Mergl graduated from the Ontario Veterinary College in 1985 and practiced for over 36 years, always in Niagara.

He was also a generous supporter of the community with his philanthropic and volunteer work, and through the years, he gave much time, energy and financial resources to many charities and organizations too numerous to list. In 2015, Dr. Mergl was recognized by the Ontario Veterinary Medical Association with the Award of Merit. This award is presented to a veterinarian for outstanding veterinary service to both the local and global community. He leaves behind his wife, Dr. June, his three sons, and many beloved animals.

We miss you, Dr. Ron! Thank you for all you have done.
