Dr. Henry Ceelen

     Henry  was born and raised on a dairy farm near the town of Hallville in Dundas County. During his formative years, Henry was an avid 4-Her and participated in multiple 4H clubs each year. He graduated from the Ontario Veterinary College (OVC) in 1981. Upon graduation, he joined the mixed animal practice of Dr. John Henry in Kemptville. In 1985, Dr. Ceelen assumed ownership of the practice when Dr. Henry retired. During the next twenty five years, the practice grew to employ six veterinarians. In 2009, Dr. Ceelen amalgamated the large animal portion of his practice with that of Prescott Animal Hospital to form Rideau-St. Lawrence Veterinary Services.
     Dr. Ceelen is the Past President of the Ontario Association of Bovine Practitioners, as well as a past president of the Central Canada Veterinary Association and has served on the Board of Directors of the Ontario Veterinary Medical Association.
     Henry enjoys providing veterinary care to all species of animals including dogs, cats and horses, but his passion remains cattle, particularly dairy cattle. He was one of the first graduates of the Dairy Health Management Certificate Program hosted by OVC. This program revolutionized dairy veterinary practice by emphasizing preventative animal care in contrast to a treatment and emergency care model. Henry strives to improve the performance and welfare of his cattle patients through preventative medicine, nutrition, and facility and housing design.
Dr. Ceelen lives outside Kemptville with his family. Henry enjoys sports of all kinds, including hockey and fold. He also enjoys maintining, improving and caring for his property.
