Karen Perry, BVM&S, MRCVS, CertSAS, DECVS, MSc Vet Ed
Pat Carrigan Professor of Feline Medicine

Dr. Karen Perry specializes in traumatology, feline orthopedics, arthroscopic surgery, and the use of negative pressure wound therapy to minimize wound-associated complications in orthopedic patients. She became a diplomate of the European College of Veterinary Surgeons in 2011 and became a Fellow of the Higher Education Academy in 2014. Perry’s goal is to increase the feline case load, increase the use of minimally-invasive arthroscopic surgery and expand the use of negative pressure wound therapy into the orthopedic department in collaboration with the existing expertise in the soft tissue department.

Maria Podsiedlik, DVM, MSc, DACVS (Small Animal)
Assistant Professor

Dr. Podsiedlik joined MSU College of Veterinary Medicine as an assistant professor (HP) in Small Animal Orthopedic Surgery in November 2021.

Dr. Podsiedlik earned her DVM from the Warsaw University of Life Sciences (Poland) in 2016.

During her residency and master’s degree research, Dr. Podsiedlik authored manuscript on cervical paravertebral nerve blocks in dogs and co-authored article on anastomotic techniques.

Dr. Podsiedlik’s current clinical interest include total joint replacement (hip), traumatology and arthroscopic surgery. She has a strong passion for and several years of teaching experience as a lecturer and clinical instructor.

Danielle Marturello, DVM, MS, DACVS
Assistant Professor

Dr. Danielle Marturello completed her surgical residency training at MSU with a dual Master of Science program. Her work focused on the development of a feline bone substitute and mechanical testing of feline orthopedic implants, and has been presented at both national and international meetings. Marturello, Dr. Karen Perry, and Dr. Loïc Déjardin were also the first to publish clinical results from the feline I-Loc, an interlocking nail implant developed by Déjardin.

Marturello is particularly interested in traumatology and biomechanical testing of orthopedic implants. Her current research activities, in addition to mechanical testing, are focused on 3D printing with interest in development of patient-specific instrumentation and implant design.



Tessa Adams, DVM
Surgery Resident

Dr. Tessa Adam was born and raised in Atlanta, Georgia, but chose to attend college in Southern California to see a different part of the country.

"I have always been fascinated with the natural world and explored my interest in ecology while at Pomona College. I enjoyed this field of research, but I ultimately decided that veterinary medicine was my true passion. I attended Michigan State University College of Veterinary Medicine and completed a rotating internship at The Ohio State University Veterinary Medical Center. During my internship at OSU, I realized that I wanted to specialize in surgery because it is an intellectually stimulating field that allows veterinarians to take an active approach in the treatment of a disease or injury. I completed a surgery internship at Friendship Hospital for Animals in Washington, DC in 2022, where I delved further into the field of surgery and began to develop my surgical skills. I am excited to have returned to MSU College of Veterinary Medicine for a surgical residency. I place great importance on providing excellent patient care and client communication for all surgical patients. My special areas of interest in surgery include post-operative analgesia, surgical oncology, wound management, and fracture repair."
