About Us 


Diane Krasznay, DVM

Graduated with a DVM from Virginia Tech in 1989. She has worked in Pennsylvania, Virginia, and Maryland for 35 years combined in small animal medicine, surgery, emergency medicine, and as a relief veterinarian.   In 2005, Dr. Krasznay started her own mobile/house call practice in Southern MD and in recent years, she has limited her practice to primarily in-home euthanasia and hospice care services.  Dr. Krasznay loves being able to provide a valuable service by providing caring, compassionate veterinary care for pets in their homes for clients within St. Mary’s, Charles, and Calvert Counties in Maryland. Dr. Krasznay is married with 2 children, several horses (thoroughbreds), 3 dogs, 1 cat, and 2 goats.

Katrina Hall 

Has been with Action Care Mobile Vet since 2007 and has been a veterinary technician since 1997, previously working at Three Notch Animal Hospital as well as the Humane Society of Charles County. Katrina is married and has a dog, a miniature horse and a new QH cross gelding that she enjoys riding. Katrina takes care of a few horses and works full time as an automobile service advisor in Lexington Park.  However, helping animals is Katrina’s passion. She states “I am always willing to go the extra mile to help in any way I can. 


Jennifer Heern 

Has been with Action Care Mobile Vet since August 2016 and loves the interaction she gets from talking with clients on the phone. She has also worked in a veterinary hospital in New Mexico as a veterinary technician for several years. Jennifer loves camping so she, her husband, and their 4 kids travel all over the Country (full-time!) in their RV and homeschool their kids.  Besides their family, they travel with 3 dogs, a cat, and a snake. 

Candy Trexler 

Was born in Nevada and has lived all over the Country as well as in Bermuda and Japan, before settling in Southern Maryland in 2006.  She knew she wanted to take care of animals at a young age, so she started her career as a ranch hand in Virginia for a horse farm.  Candy then became a groomer for 10 years and then worked as a veterinary assistant and finally, a veterinary technician.  Candy previously worked for Action Care back in 2007 but needed full time employment, so she accepted a position with All Kinds Veterinary Hospital as a veterinary technician and retired after 17 years.  Happily, for us, Candy is now available to work part-time with Action Care Vet again!
