Our Story

We would like to introduce ourselves! We are Doctors Sheri Clarkson and Heather Suttie. Our team have all called Calgary home for many years with strong ties to the community. We have felt that there was a need in Calgary for a progressive, innovative and compassionate emergency practice that functions efficiently and with integrity. With different strengths and backgrounds, we have come together to fulfill a shared dream to serve needs of Calgary’s pets, clients and referral community. Trinity Hills 24 Hour Pet Hospital started as a pile of dirt and a dream in 2018 and has been so incredibly rewarding to develop this project. We pride ourselves on providing exceptional care and truly love practicing veterinary medicine. 


We will be a flagship of affordable and ethically based veterinary care stressing that there is always something that can be done to help.



Our company values of Quality, Integrity, and Learning are the core principles that motivate us and what we will invest in and evaluate ourselves by to meet our goals.

          New reproduction service policy – As of December 19th 2022, we will only perform progesterone testing on females over 1 year of age. We do not collect or breed every dog that is presented to us as it is our goal to only partner in helping to create healthy puppies. We will require breed specific health testing according to your breed's parent club. Requirements for each breed can be found at www.ofa.org/browse-by-breed
