Dr. Dan Cederstrom, DVM, Owner
Dr. Dan first joined Park Grove in 1992 as a part-time associate veterinarian, and then eventually purchased the practice in 2001. In 2003, the clinic had to be moved to its current location. He graduated from Iowa State University with a major in animal science and his Doctorate of Veterinary Medicine. He completed his internship at Boren Veterinary Teaching Hospital in Stillwater, Oklahoma.
Dr. Dan resides in the Woodbury area in the house his wife, Sue, grew up in (her family has been in the Woodbury community for over 100 years!). Together, they have four children and one grandchild, and a Lab, Gertie. Outside of the clinic, Dr. Dan enjoys spending time with his family, volunteering at Afton Alps as a ski patrol, being active in his church, and many other outdoor activities.
Dr. John Sturtz, Associate DVM
Dr. Sturtz has been with Park Grove Pet Hospital since 2006. He has a BA in mathematics and computer science from Carleton College and his DVM license is from the University of Minnesota College of Veterinary Medicine. His favorite thing about veterinary medicine is helping our clients’ bond with their companion animals, as he has done with his own two Golden Retrievers (Tally and Tiya) and kitties (Orrefors and Baccarat).
When not engaged in veterinary medicine, he enjoys jazz singing, musical theater, golf, technical writing for a programming website, and walks with Tally and Tiya.
Dr. Sonja Wiersma, Associate DVM
Dr. Sonja joined Park Grove as a doctor in 2011. She graduated from the University of Wisconsin, River Falls with a BS in 2005. Then it was off to Iowa State University, College of Veterinary Medicine, to receive her DVM license. Dr. Sonja’s special interests include behavior, surgery and dentistry, pain management, and preventative medicine.
Like anyone in this field, she loves animals, but her inspiration came from the interaction she had with the veterinarian of her first cat. At the age of 7, she remembers the veterinarian took time to answer all the questions she had for her cat, Tootsie. Even though Tootsie didn’t make it through his illness, she will never forget the care and compassion that the vet gave to both her and Tootsie. Dr. Sonja wanted to make the difference for others the way he did for her.
Outside of the clinic, she enjoys camping, gardening, and reading. She also enjoys spending time with her husband, Brent and their families, friends and dog (Booth), their Cats (Jaden, Mama, and Munchkin)
