Emergency & Critical Care Specialist
Deb Morey, an emergency and critical care specialist, obtained her DVM from UC Davis in 1992. After graduation, she completed a year-long internship in small animal medicine and surgery at the Sacramento Animal Medical Group. Debbie then moved to Fresno for a year of intensive emergency and critical care experience at the Veterinary Emergency Service before returning to Sacramento to head up a 24-hour vet emergency department for a specialty hospital over the next four years.
In 1998 Dr. Morey embarked on a residency training program in Emergency Medicine and Critical Care while also working at several busy emergency practices and raising two children. In 2005, she successfully passed the rigorous examination to become a Diplomate of the American College of Veterinary Emergency and Critical Care.
After 10 years as a critical-care specialist for some of the best 24-hour veterinary hospitals in Northern Calfornia, Dr. Morey joined MarQueen Veterinary Specialty Group in 2015 and has been a vital part of the wonderful culture at MarQueen Veterinary Specialty and Emergency Group. Her veterinary critical-care knowledge and her attentiveness to clients and patients are some of the best in California. We are proud to have her as part of our family in Upland.
Debbie’s professional interests include shock resuscitation, critical care monitoring, nutrition, wound management, and training veterinarians and technicians in critical care techniques. When off duty, she enjoys spending time with her 2 boys, 2 dogs, and 5 cats. She also enjoys downhill skiing, running, hiking, and wine-tasting.

Dr. Ulhaq’s special interests include dermatology, internal medicine, radiology, and surgery.
Dr. Ulhaq has been an associate emergency doctor at our 24-hour veterinary emergency hospital, MarQueen Pet Emergency and Specialty in Northern California for more than six years, working alongside some of the best veterinary specialists in surgery, oncology, emergency, and critical care, cardiology, as well as one of the best Internal Medicine Specialists in the country, Dr. Erica Queen.
Dr. Nicole Ulhaq brings a wealth of 24-hour vet experience to Upland, as well as the culture and veterinary care that has made MarQueen one of the best and only remaining independently-owned veterinary hospitals in the region.
Richard Strasser, DVM
Dr. Strasser was raised near Seattle and attended the University of Washington where he received his bachelor’s degree in ancient military history. He went on to serve our country in the United States Marine Corps where he served four years in the infantry. Dr. Strasser returned to college in 2002 where he graduated from the UC Davis School of Veterinary Medicine.
With many years of diversified veterinary experience, Dr. Strasser practiced at several general practice clinics before he returned to his original passion – emergency and critical care medicine in 2018. He continued to build and grow his 24-hour vet experience and knowledge as he practiced veterinary medicine at veterinary hospitals across several states, which include the original MarQueen Pet Emergency and Specialty developed by Veterinary Internal Medicine Specialist, Dr. Erica Queen. Dr. Strasser is now a partner of MarQueen Veterinary Specialty Group in Upland and looks forward to helping both clients and their dogs and cats through the night. An experienced, caring, and humble veterinarian.
During his free time, he likes to be outside- hiking with his dog, riding bikes (dirt and mtn.), overlanding, and fly fishing.
Jasmine Choi, DVM
Dr. Jasmine Choi is an experienced emergency veterinarian and a native of Southern California. She achieved her undergraduate degree from the University of California, Irvine in Biological Sciences with the goal of being an ophthalmologist in human medicine. It was by chance that Jasmine volunteered as a kennel attendant and fell in love with the idea of helping dogs and cats.
Over the span of the next six years, Dr. Choi worked her way up as a veterinary technician assistant and grew her experience in the veterinary field before she decided to attend Western University College of Veterinary Medicine. After completion of veterinary school, Dr. Choi completed a small animal rotating internship at a veterinary specialty hospital in southern California. She continues to grow in all areas of veterinary medicine with surgery, pathology, and, of course, ophthalmology, as her main interests.
Once MarQueen Veterinary Specialty and Emergency opened a hospital in Upland, Dr. Choi was eager to be a part of this group of ER veterinarians, specialists, and experienced staff. MarQueen is fortunate to have an extremely dedicated and focused emergency doctor.
When not at the hospital, Jasmine stays active with running, cycling, surfing, or chasing her cat, Willie, for his nail trims. Otherwise, you can find her climbing at a local crag or planning her next big trip to find world-class bouldering somewhere around the world.
Travis Vasconcellos, DVM
Travis Vasconcellos, DVM, grew up in a residential area in O’ahu, Hawaii, in a large family of blue-collar workers. As a child, Travis would spend his summer days with his grandfather to help him care for all types of birds – lovebirds, parakeets, finches, ducks, and chickens. It was in these moments Travis’ grandfather saw something in Travis.
In 2013, Travis completed his undergraduate degree in Biological Sciences at the University of Hawaii. While Travis contemplated a career in the construction industry, he was accepted into Washington State University Veterinary School of Medicine and decided to continue the pursuit of Veterinary Medicine. In 2019, Travis graduated from veterinary school and became a veterinarian. Dr. Vasconcellos began his internship at a busy emergency practice in Southern California. In 2022, Dr. Vasconcellos joined the MarQueen Veterinary Specialty Group as a 24-hour emergency hospital veterinarian.
As children, our grandparents see our futures through love and wisdom, and the grandfather who told his nine-year-old grandson that the boy would become a “pet doctor” one day was sure right about Dr. Travis Vasconcellos.
When Travis is not saving lives, you can find him surfing, snowboarding, or hiking. He also loves to sip artisan beers and cheer at the television during Baltimore Ravens games while his cat Winter silently judges him.
Stella Chu, DVM, CVA, CCRT
Stella Chu spent her childhood and teenage years in New Jersey. It was only appropriate that she earn her Bachelor of Science degree in animal science at Rutgers University. Dr. Stella Chu then obtained her Veterinary Medical Doctor degree at the University of Pennsylvania in 2015. Soon thereafter, Dr. Chu completed a one-year rotating internship in medicine and surgery at the University of Illinois in 2016, which was then followed by a specialty internship in internal medicine at Red Bank Veterinary Hospital, New Jersey, in 2017. After her two internships, Dr. Chu moved to Southern California and started her career working as an emergency veterinarian. She joined MarQueen Veterinary Specialty and Emergency Group as an emergency doctor in 2022 and has now joined full-time to grow her specialty skills while helping the emergency department.
After years of practicing medicine in the emergency room, Dr. Chu also completed her certification in veterinary acupuncture at Chi University in 2020 and is currently enrolled with the Canine Rehabilitation Institute working towards certification as a canine rehabilitation therapist.
Dr. Chu offers acupuncture and Chinese herbal medicine in her rehabilitation practice to facilitate optimal outcomes for post-operative patients and increases the quality of life for senior pets.
In her free time, Dr. Chu bakes all things warm and delicious, yells at football games on TV (go Giants!), travels, thrives on live music, and spends time with her husband, two pugs, and three cats.
Monica Zamora, DVM
Monica Zamora grew up in and around Long Beach, California. She moved to the Inland Empire where she attended college at Cal Poly Pomona and received her BS degree in pre-veterinary studies to pursue her goal to be a veterinarian. Monica combined her love of Southern California with veterinary school and obtained her doctorate in veterinary medicine from Western University of Health Sciences. It was during the latter years of veterinary school that Dr. Zamora discovered a passion for 24-hour veterinary emergency medicine with a focused interest in traumatic soft tissue surgery, toxicology, endocrine emergencies, internal medicine, traumatic brain injuries, and pain management. With many years of experience working alongside specialists and surgeons, her knowledge and passion for helping dogs, cats, and clients have grown stronger. MarQueen 24 hour veterinary hospital is fortunate to have Dr. Zamora join our family of surgeons, internal medicine specialists, critical care technicians, and front staff in Upland, California. During her time off, Dr. Zamora loves to hit the leather off the ball in her co-ed softball league but retired a few years ago to root for her beloved Los Angeles Dodgers. In her downtime, she enjoys hiking, trivia nights, and dining out with her dog at pet-friendly restaurants.
Courtney Malone, DVM
Dr. Courtney Malone is a native of the Inland Empire as she grew up in Rancho Cucamonga, where she attended Los Osos High School and was a local stand-out volleyball player. Courtney was such a stand-out volleyball setter that she accepted a full-ride volleyball scholarship from UC Riverside, where she completed a BA degree in Global Studies.
However, a desire for veterinary care was always there, and after her career at UC Riverside, Courtney went on to complete her BS in Biology to attend Western University of Health Sciences Veterinary School, where she obtained her DVM license. Dr. Malone then started her career as a veterinarian with a general practice in the Lake Arrowhead area. As a family veterinarian, Courtney would have patients come in that needed further emergency and specialty care, which required a transfer to a 24-hour veterinary emergency facility. It was within these difficult cases that Dr. Malone realized she wanted to help dogs and cats in these next steps. She eventually left general practice to become an emergency veterinarian in the Riverside area.
As an emergency doctor, there would be specialty cases that needed to be transferred to a specialty hospital for urgent care by an internal medicine specialist or surgeon. It was, once again, during these transfers to MarQueen Veterinary Specialty Group that Dr. Malone realized she wanted to be an ER veterinarian working with specialists.
Whether it was playing collegiate volleyball at the highest level or practicing veterinary medicine, Dr. Malone’s intrinsic desire to keep growing to be the best within a family of colleagues is what makes her unique, not to mention a great personality.
Courtney also has a love of photography and a love for her dogs and cats – she has many photos of them! She also has a love of nature, where she hikes the mountains, kayaks the rivers, and loves to fish alongside her husband, who is a high-ranking fireman in the community. MarQueen Veterinary Emergency and Specialty is proud to have Dr. Courtney Malone.
