Our Story

The Clinique Vétérinaire du Vieux Longueuil is an independent practice, owned by Dre Astrid Pacher since April 1st 2016. Having graduated from the University of Montreal in 2006, Dre Pacher had been dreaming of owning her practice for multiple years. Passionate, Dre Pacher is a firm believer in quality medical care as much as personalized and warm customer service. Since 2021, the Clinique Vétérinaire du Vieux Longueuil’s practice is focusing on the use of stress-free techniques. We want to ensure that each one of our patients experiences the most agreeable and least stressful visit possible. 


Over the years, the team has steadily grown. Each team member whole-heartedly adheres to the values that define the Clinique Vétérinaire du Vieux Longueuil: empathy, attentiveness, respect and excellence.

Dr. Astrid Pacher

After graduating from University of Montreal in 2006, Dr Pacher worked in various clinics in the greater Montreal area before acquiring her own practice in Old Longueuil in 2016. Her passion for animals made her choose this career path but the strong bond built with her clients is what kept her on it. By preserving the special bond between a pet and their owner, Dr Pacher knows she makes a difference in her clients’ lives. Her dedication has never faltered since her early years as a veterinarian. As time went by, Dr Pacher developed a special interest in surgery and geriatrics. She particularly enjoys treating elderly patients and ensuring they maintain a good quality of life in their golden years. Outside of work, Dr Pacher is a music enthusiast and you will often find her on a dance floor!

Meet Tibo, our first mascot! Very sociable, he loves getting pet by all clients. Naturally curious, he explores all areas of the clinic and often meows in front of closed doors!  He loves drinking water straight from the faucet and is a real glutton!




Meet Mama, our second mascot! Being a little shy, she prefers to observe things from a high vantage point. When things are quieter, she adores lying on our employees’ laps. Getting brushed in one of her favourite activities and a sure way to score points with her!
