Dr. Andrew Loar, DVM, DACVIM (IM and Oncology) – Co-CMO, Co-Founder and ZNHub Lab Director

Andy was raised in a traveling military (USAF) family and moved nearly a dozen times before finishing high school in Atlanta Georgia. He attended McGill University, in Montreal, for his undergraduate studies and graduated from the University of Georgia with his DVM (1979). He completed an internship at Louisiana State University and his residency in oncology at the Animal Medical Center in New York City.

He has served on the clinical staffs at the veterinary schools of Virginia Tech and the University of Wisconsin, as well as the West Los Angeles Veterinary Medical Center. He received dual board certification with the American College of Veterinary Internal Medicine (ACVIM: Internal Medicine {’84} and Oncology {‘94}). He was the first veterinary oncologist to practice in southern California and operated oncology referral clinics in Los Angeles, Orange and San Diego counties from 1985-1995. Dr Loar completed additional training in clinical pathology at Oklahoma State University.

In 2000, after returning to the Animal Medical Center (NY) as staff clinical cytologist, he subsequently co-founded ALX Laboratory, a small, ambitious commercial reference pathology laboratory in Manhattan, which was purchased by IDEXX in 2011. From 2012 until 2017 he was the clinical laboratory director and consulting cytologist at STAT Veterinary Lab, a facility originally created as the in-clinic reference laboratory of the Veterinary Specialty Hospital in San Diego. Veterinary Specialty Hospital merged with other specialty hospitals in 2015 to become Ethos Veterinary Health, with more than 17 clinics in 6 states and Hong Kong; Dr Loar became VP of Laboratories for Ethos Veterinary Health. In 2016 he implemented a second core veterinary reference laboratory for Ethos in the Boston area.

During his more than 30 years in various veterinary diagnostic spaces he has served as a cytologist and oncology/internal medicine consultant at Veterinary Reference Laboratories, Professional Animal Laboratory (now ANTECH), IDEXX Laboratories, Ethos Diagnostics and Animal Reference Pathology (ARP).  Andy recently moved to Louisville, KY to oversee all clinical operations of the ZNHub.  He is otherwise a frequent world traveler, has many fine leather-bound books and knows people you know.

Dr. David Gardiner, DVM, MS, DACVP – Co-CMO, Chief Pathology Officer and Co-Founder

Dr. Gardiner, AKA DG1, received his Doctor of Veterinary Medicine (DVM) degree from Cornell University and completed his veterinary anatomic pathology residency and Masters of Science (MS) degree at Colorado State University and is board certified in veterinary anatomic pathology by the American College of Veterinary Pathologists. After pathology residency training, Dr Gardiner dove head first into surgical pathology at IDEXX Laboratories West Sacramento lab and eventually became the regional head of anatomic pathology for Canada and the western United States for IDEXX.  Wanting to try and do things a different way in the veterinary diagnostic lab industry, with Mr Smith (ZNLabs CFO), Dr. Gardiner and Mr. Smith purchased the Animal Reference Pathology (www.animalreferencepathology.com)  division of ARUP Laboratories.

The idea for ZNLabs developed out of running Animal Reference Pathology, interactions with Dr Loar (ZNLabs Co-CMO), Mr Gersholowitz (ZNLabs CEO) and a desire to offer veterinarians a viable 3rd option in the veterinary reference laboratory space. No one was doing anything about it and despite prior unsuccessful attempts (AVRL), we decided to make it happen.

A member of the American Veterinary Medical Association, the American College of Veterinary Pathologists and the International Society of Veterinary Dermatopathology, Dr Gardiner is particularly interested in pathology laboratory management, ocular pathology, dermatopathology, and oncologic pathology. Dr. Gardiner is an adjunct professor in the School of Veterinary Medicine at Utah State University where Animal Reference Pathology sponsors an annual veterinary spelling bee. Close your eyes and can you spell intussusception?

 Juan Pablo Svencionis, MS – Manager, Molecular and Microbiology Services

Juan Pablo was born in Canton Ohio, but was raised in Argentina, hence the accent.  He started showing interest in Biology, particularly DNA, at a young age and that made him pursue a degree in the field.  He graduated in 2011 from the University of Buenos Aires, with a Bachelor of Science in Biological Sciences with an orientation in Molecular Biology and Biotechnology.  With a degree and limited options in Argentina, he decided to come back to the US to pursue a Master’s Degree in Microbiology, Biochemistry and Molecular Biology from Southern Illinois University.  He was introduced to veterinary diagnostics at a large dairy farm where he developed a passion for fast and quality lab results. As soon as he learned about ZNLabs he jumped at the opportunity to join an awesome team and begin the revolution of veterinary diagnostics.  In fact, Juan is ZNLabs’ first employee and a proud shareholder 🙂

Juan is happily married to Ayelen and the proud dad of Oliver. When he gets time, he enjoys fly fishing (although it is generally less about catching fish and more about him looking sharp in a pair of waders).

 Ashley Lee, BA – Marketing Manager

Ashley’s life started much like many other military brats; moving from city to city, never quite convincing her family to take the cool deployments overseas, and picking up an alarmingly robust collection of accents. Eventually her nomadic lifestyle landed her in California where she discovered her love for all things tea and beach related. Earning her Bachelor’s at California State University Chico in 2013 she dove head first into the wonderful world or marketing and graphic design and eventually settled down in Florida to be closer to her mother and their much loved dogs, Jack and Daisy.
With seven years of marketing and graphic design experience, and a love for animals that has spanned her entire life, Ashley is excited to bring her portfolio of (ninja) skills to the table and help the ZNLabs team reach new heights. When not hard at work masterminding marketing strategies Ashley can often be found eating her weight in tacos or chasing after other peoples dogs to the pet them.
