Our Team:

Dr. Sue Sterr received her undergraduate degree from Western Illinois University and is a 1995 graduate from the University of Illinois College of Veterinary Medicine. Originally from Graymont, Illinois, she spent the first five years of her veterinarian career working in Normal, Illinois. Dr. Sue and her husband bought Covenant Animal Clinic in 1999 and moved to Clinton at that time. Working with God’s creatures and their owners has been very rewarding for Dr. Sue. However, as a wife and a mother of three children, her family life keeps her equally busy. Dr. Sue and her family have two cats and Tilly, an English Setter at home.
Lynn Grammer went to work at Covenant Animal Clinic in 1994 after her veterinarian technician internship. She and her husband, Dave, have two children that keep them very busy. Lynn’s family is an animal lover. They have two dogs, two cats, and eight chickens. Lynn enjoys being a veterinarian technician because every day is different and she enjoys making a difference in the lives of the patients she works with. Lynn stays very busy keeping up with her children’s different sporting events and their family enjoys camping, boating, skiing and gardening.
Lynn Cali is originally from the Chicago area. She has always loved animals & wanted to work in the veterinary field. She has a Bachelor of Science from the U of I and an Associate degree from Parkland College in Veterinary Technology. Lynn has worked at Covenant Animal Clinic since August 1983 and still enjoys working with the animals. She has 2 dogs and 2 cats at home and enjoys traveling, gardening, reading & listening to Bruce Springsteen.
Janet Crawley has worked at Covenant Animal Clinic since January 1984 and very much enjoys her job. Although her main title is bookkeeper, she is really a “jack of all trades.” She also works as a receptionist, pharmacy aid, and wherever else needed. Janet says there is never a boring day at Covenant Animal Clinic. Having had pets all her life, she continues to live with her cats, dogs, and husband of many years, Byrl. Janet enjoys spending time with her son, daughter in-law and two wonderful grandchildren. She enjoys quilting & reading in her spare time.
Loretta Allen began working at Covenant Animal Clinic in October 2006 as a senior kennel assistant. She moved up front to a receptionist position in August 2012. Loretta has a big heart for all animals and depends on the other staff members to keep her from "saving" them all. She has 3 cats-Molly, Abby & Devil Spawn, 3 dogs-Diesel, Jack Daniels and her newest addition Harley Davidson, a Mastiff/Lab/St. Bernard mix she soon "saved" after becoming a receptionist in August. She also has a rabbit named Rabbit and a horse named Cabela. She enjoys her job with Covenant Animal Clinic very much and sees herself working with us for many years to come. She enjoys life by spending time with her family and friends and stays very busy as well with being a fire fighter/staff assistant on the Clinton Fire Department.
