Our Doctors

Dr. Johnathan Lax, BVSc  graduated from the Veterinary School (Onderstepoort) at the University of Pretoria in South Africa in 1980. He owned a Veterinary practice in Mafikeng , a rural town 100 miles from anywhere for 10 years before coming to the USA. He was responsible for the entire town’s pet population, as well as cattle ranches, dairy farms, wild animal parks, a crocodile farm, and the local horse/donkey/mule population.

Dr. Lax immigrated to the USA in 1990 with his wife Jill and after a short stay as a relief vet in Oklahoma City, moved to San Diego, where both he and Jill gained employment in North County. Jill is a very famous local high school teacher.

In 1995 Dr. Lax opened Alga Pet Hospital in Carlsbad. In August 2009 he relocated the Hospital to bigger premises in Bressi Ranch. He prides himself in trying to stay current or ahead of the curve in new developments in Veterinary medicine and brags that in 30+ years as a vet he has never had a day when he did not feel excited to go to work.

He lives in Encinitas with his wife and 2 children (Megan and Zachary), 2 dogs (Roli the lab and Byron the Basset), a Guinea pig (Sweet pea), and a tank full of VERY old fish (Carrot top, Pinky, Gumbo, Brain, Speckles... and Jaws).

His favorite hobbies are traveling with his family, playing golf, and watching his children play sports

Dr. Yolanda Kenney, DVM, Dr. Kenney is a San Diego native.  She received her undergraduate degree in music from the University of San Diego.  After working in the music industry for 5 years, she returned to school to pursue her dream of becoming a veterinarian.  She received her doctorate of Veterinary Medicine from the University of California, Davis in 2000.

While in Davis she had the unique opportunity to work with non-human primates in the veterinary hospital at The California Primate Center.  She also spent time rehabilitating injured raptors at the UC Davis Raptor Center.  But her first love is working with dogs and cats.  Her interests include internal medicine and surgery, with a special affinity for senior patients.  She joined the original Alga Pet Hospital in 2005.  In her free time she still enjoys playing the cello.  She lives in Carlsbad with her husband John and their two dogs.

Dr. Paula Dvorchak, DVM, Dr. Dvorchak is the latest addition to our wonderful team of veterinarians.  She comes to us with many years of experience as both an Associate Veterinarian and as a previous hospital Medical Director.  Dr. Dvorchak received her Doctorate of Veterinary Medicine (DVM) from the University of California Davis in 2006. She did a year of ER training at California Veterinary Specialist in Murrietta before transitioning to general practice veterinary medicine.  She has worked in North County San Diego exclusively since that time. 

Prior to veterinary school, Dr. Dvorchak received her Master’s Degree in Animal Behavior and Physiology.  She did multiple international externships during her time at Davis including ones in Spain and South Africa.  It goes without saying that traveling has long been one of her favorite activities.

Dr. Paula Dvorchak currently resides in Encinitas with husband David and her three children:  Maya, Evan and Ava.  She also shares her home with three dogs (Zoe, the Rottweiler, Lilly the Terrier and Charlie, the French Bull Dog) and three cats (Buddha, Shiva and Nala).  When she is not working and spending time with her family, Dr. Paula Dvorchak enjoys exercise (i.e, yoga & walks) and also hand makes jewelry which is sold in a few local boutiques.
