Meet some of our wonderful team members.

Greg Zamora

Regional Inventory and Equipment Specialist

Greg, who grew up in Southern California, followed his first dream of becoming a welder by completing his AWS with LA Certification. He shortly realized that his love for animals would be his passion and jumped in to developing a career in animal care. Starting his new career as a Kennel Assistant, Greg focused on developing his skills and knowledge in the Emergency field.

Greg has been with the ACCESS family since 2003, first working in Tustin, California at ACCIM. He then helped establish the Los Angeles location, working here from day one in 2005. Bringing all that he has learned in the emergency field both as an animal care attendant and equipment/purchasing manager, he has continued to be a valued asset as we transitioned to ACCESS Specialty Hospital Group and helped make opening ACCESS in Woodland Hills a success. Maintaining strong ties to the veterinary community and dedication to animals, when not at ACCESS-Los Angeles, he can be found working with a mobile orthopedic veterinarian.

Greg currently serves as the Technician Supervisor and Purchasing Manager at ACCESS-LA, responsible for the daily management of our veterinary technicians and paraprofessionals in all seven departments of the hospital. He helps ensure we bring quality, integrity, and compassion to all aspects of care for our patients. He also helps purchase and maintain the leading medical equipment and supplies that allow us to meet such highs standards of medical care.

Although Greg affords himself very little time away from the veterinary world, he does like to deep sea fish or work on his ’47 Chevy when able. At home his buddies are a French Bulldog and a Cat named Mimi.

Jason Bitting

Director of Operations

Jason is a native of New Jersey. Prior to entering into the field of veterinary medicine, he lived in New York City for approximately 12 years where he worked in restaurant management before owning an establishment of his own. Although he has always maintained a great fondness for food and wine, he felt as if he wasn’t following his true passion and so, sold his restaurant after five years.

Jason had known for many years that he wanted to work with animals. During a blackout in New York City in the summer of 2004 he had volunteered for the ASPCA in Manhattan’s Upper East Side. Subsequently, it was this experience that changed his life forever. He spent the next six years gaining the knowledge and sharpening his skills as a technician in the area of emergency and critical care and surgery. He developed a profound interest for anesthesia and was eventually promoted to head surgery technician. He has logged over 5000 hours administering and monitoring anesthesia during not only elective procedures but with orthopedic and critical cases as well.

For the past two years Jason has held the position of Hospital Manager for a large general practice and 24-hour emergency facility in New Jersey. He thoroughly enjoys being part of the client/patient/provider dynamic and is always eager and willing to help his fellow team members facilitate the components necessary for ensuring the highest quality of patient care and client service.

Jason is just a few credits shy of earning his bachelor’s degree in business administration and management. His future goals include becoming certified as a practice manager (CVPM) and earning a master’s degree as well. When not working, Jason thoroughly enjoys volunteering his time, classic car culture, engaging in outdoor activities (hiking, running, etc.), practicing the martial art of kung fu and tai chi, and spending time with his two cats Mimi and Olivia.

Lance Dickson

Technician and Purchasing Manager | ACCESS – San Fernando Valley

Originally from Houston, this Southern Gent attended—you guessed it— the University of Houston! He’s always loved animals and attended a job fair where he found a career as a veterinary assistant. He was able to do some on the job training and eventually earned his Certified Veterinary Assistant certification, or CVA. It’s been all animals, all the time ever since!

Though he adores all animals, Lance has a special place in his heart for domestic cats. He “finds their personalities intriguing. They’re sensitive, so you have to treat them gently. One cat may not like having his belly rubbed, and another may love it. Veterinary medicine is all about figuring out the pieces of the puzzle to make it work.”

He moved to California in 2006 and joined our San Fernando Valley team in 2012. The opportunity for a leadership position came, and in late 2017, Lance became the Technician Supervisor and Purchasing Manager for the hospital…though his true claim to fame is holding the title of 1993 Tae Kwon Do State Champion.

Leah Basinais, MBA

Chief Operating Officer – ACCESS Specialty Animal Hospitals

Leah Basinais was faced with a serious choice at the age of 16. Summer job: a kennel assistant at a vet hospital, or a sales clerk at a surf shop. Tough choice for a teenager, but the furry friends won out, setting the stage for what would be a career revolving around veterinary medicine.

With a bachelor’s degree in biology from a tiny college in Milton, Massachusetts and a prestigious internship at the Tumor Genetics Lab in Massachusetts General Hospital under her belt, Leah returned from Boston to get married and set up a life back in Los Angeles. After a brief stint in a PhD program at UCLA in microbiology, Leah decided she was better with people than she was with nematodes.

Returning to her comfortable home as a veterinary receptionist, she rose to become a manager of a small general practice in Sherman Oaks, CA. In 2001, Leah moved to become a Hospital Administrator of a large multi-specialty hospital in Ventura, CA, where she furthered her education by completing a Master’s degree in Business Administration with a specialized certification in Health Care Management. She was the President of the Veterinary Specialty Practice Alliance (VSPA) and has lectured internationally.

Now a happy member of the ACCESS family, Leah is focused on operational improvement, service training, systems creation, and personnel development. An advocate for providing clients with exceptional support during difficult times, Leah is excited to help ACCESS realize its exceptional potential as a leader in specialty medicine.

From then on, she knew she wanted to make an impact on the lives of people and pets. She was a kennel assistant, and went on to fulfill nearly every role in the hospital – veterinary assistant, veterinary technician, client service specialist, and Practice Manager in Houston, Texas. During this time, Talia also earned her bachelor’s degree at the University of Houston.

After returning home to Long Beach, California, Talia began consulting with the American Animal Hospital Association, evaluating veterinary hospitals across the nation on rigorous standards of patient care, while attending Colorado State University for her MBA. She earned a Certified Veterinary Practice Manager (CVPM) designation, awarded only to managers committed to the pursuit of excellence in veterinary practice management through continual education in the veterinary profession.
