Dr. Ceballos was born in West Covina, California, but grew up in a small town called Mariposa, which he still loves to visit. He graduated from California State University, Stanislaus in 1995 with a degree in biology and a minor in chemistry, and started veterinary school that same year. He graduated from Tuskegee University School of Veterinary Medicine in 1999, and then moved to Las Vegas.

Dr. Ceballos worked at Tropicana Animal Hospital for a year and a half before opening Sunridge Animal Hospital in 2001 as head doctor and manager. In January 2015, he officially became the proud owner of Sunridge Animal Hospital. Dr. Ceballos’ professional interests include surgery, orthopedics, reptiles, large cats, and exotics. His personal interests include camping, cooking, fishing, playing the guitar, and visiting Mariposa.

You’re sure to be in great hands with Dr. Ceballos. He has many years of experience working as a veterinarian at places like the Silverton Aquarium and Las Vegas Zoo, and has also spent several years with the Department of Wildlife. He has worked with lions, Gila monsters, eagles, and other wild birds, all while managing to balance his time at Sunridge.

Marisda Rosa, DVM

Dr. Rosa was born and raised in Puerto Rico where she attended the University of Puerto Rico, Mayaguez, earning a bachelor degree in animal science. She moved to Alabama in 2003 to study veterinary medicine at Tuskegee University, graduating in 2007. Dr. Rosa joined the Sunridge family in 2007 and has been a vital part of our team. Her primary interests include internal medicine, geriatric health care, and preventative care.

Dr. Rosa is very passionate about her patients, making sure that they are happy and as pain-free as possible. She has a furry family of rescues that are a huge part of her life. She loves visiting her family and friends—and the beaches in Puerto Rico! In Nevada, she enjoys dining out and trying new restaurants, the movies, camping with friends, and having a relaxing day at the spa.

Dr. Rosa has been a vital part of the clinic since she joined us in 2007. With her experience she is one of the best at her craft. She cares fiercely for each patient and won't rest until she knows the animal is well taken care of. Combined with Dr. Ceballos, they make an excellent team. There is rarely something they cannot do. If there is something they are unable to do, they will refer the patient to specialty to make sure they get the care they deserve.

Ashley C. Izaguirre-Alomar, DVM

Dr. Izaguirre-Alomar was raised around animals thanks to her grandfather, so it was only natural for her to develop a love for animals herself and want to help them stay healthy. Her education includes Pontificia Universidad Catolica Recinto de Arecibo, PR, Ross University, and Louisiana State University (where she spent her clinical year). One of the things Dr. Izaguirre-Alomar loves most about practicing medicine is experiencing the joy of keeping animals happy and healthy. They are so easy to love, and are always grateful for the help they receive.

Dr. Izaguirre-Alomar has a pet bearded dragon. Outside of work, she enjoys traveling, skating, and various outdoor activities.

Dr Mendez 1

Christian Mendez, DVM

Dr. Mendez came to Sunridge Animal Hospital for the opportunity to start his veterinary career in a busy practice that treats a wide variety of species, and to remain close to his family in California. He attended the University of California in San Diego and obtained his DVM from Midwestern University College of Veterinary Medicine. Dr. Mendez is Fear Free Certified and his professional interests include soft tissue surgery, preventative care, and shelter medicine.

Dr. Mendez became a doctor out of respect for the human-animal bond, and because he wanted to provide honest care to help animals in need. He loves being able to care for your “furry” family members, along with treating various species and performing surgeries on different species and improving their quality of life.

When not at work, Dr. Mendez enjoys working out, hiking, running, playing sports, trying new food, and watching sports. He and his wife share their home with a dog named Pelusas and a cat named Chin Chin.

Fun fact: Dr. Mendez was president of the Shelter Medicine Club in veterinary school.

Dr. Mendez is incredibly kind and efficient. He often allows the staff to watch him as he is doing a surgery or treating a patient so that they are able to learn and hone their craft. He has such a fun personality and is a great doctor.  

Jasmine Lyons, DVM

Dr. Lyons received her Bachelor of Science degree from Howard University and earned her DVM from Tuskegee University. She is also a Fear Free Certified Professional. Dr. Lyons loves her patients, and one of the things she really enjoys about practicing veterinary medicine is having the ability to advocate for those who cannot speak for themselves.

Dr. Lyons shares her home with her beloved Standard Poodle, Santiago, a tuxedo cat named Blackjack, and a bearded dragon named Chico.

Katie Stout Lead Technician

Katie has been in the veterinary field for over a decade. She majored in animal science and nutrition at West Virginia University, where she was a part of the WVU Poultry Judging Team (yes, it’s real). She also started working nights at a veterinary emergency hospital during this time, and that’s when she fell in love with veterinary medicine. After school, Katie went to another animal hospital and eventually became the ER tech lead before moving to Las Vegas in 2018.

While she enjoys most aspects of veterinary medicine, Katie has a particular love for emergency and critical care. Seeing a critical patient that she’s taken care of for days turn a corner and start to improve is extremely rewarding.

On the personal side of things, Katie is a die-hard WVU football fan (let’s GOOOOO Mountaineers!), and she loves live music, baking, binge-watching TV, and reading. She recently lost her dog, Holly, so she and her husband have decided to spend some time traveling while they wait for their next pet to find them.
