Dr. Naomi Weinberg

Dr. Weinberg was born and raised in the Bay Area in California. She obtained a degree in veterinary medicine in 2011 from the UC Davis School of Veterinary Medicine and went on to an equine internship at West Coast Equine in Southern California. Since then she became an on-site ranch veterinarian, taking care of 11,000 goats, 6,000 rabbits, 150 reining Quarter horses and 150 head of beef cattle. Following this experience, she took a large animal ambulatory and small animal in-hospital veterinary position in Somerset, Pennsylvania.

 

Dr. Weinberg met Dr. LeFave during their acupuncture certification course in Colorado, both searching for the ability to relieve pain and discomfort in their patients that “modern medicine” did not seem to completely prevent. When they both realized their passion for animal therapy and rehabilitation, they kept in touch. A year later Dr. LeFave opened Back to Health with Cheryl Ziemba and invited Dr. Weinberg to join their growing practice.

 

Dr. Weinberg is happy to be back in California, working in a small animal emergency clinic and practicing at Back to Health.

 

In her spare time Dr. Weinberg is rehabilitating her horse, Barbie, from a suspensory ligament injury. She brings her blue pittie Jelly Bean in to Back to Health for water treadmill and laser therapy sessions following bilateral ACL injuries and TPLO surgeries to keep him happy and healthy, and you may see her other fur babies Cheese and Squirt in the clinic. You may see her either practicing yoga or driving up to Mammoth for a hike or fun in the snow.

Dr. Veronica Contreras

Dr. Contreras was born and raised in Southern California, and she attended the University of California, Santa Cruz and UC Riverside for her B.S. degree in biology. She then attended UC Davis School of Veterinary Medicine, where she obtained her Doctorate of Veterinary Medicine in 2016.

 

During her time at UC Davis, she was a leader in various clubs whose goals were in line with her passions (education, diversity, volunteer work, and OneHealth) and was also one of the lead veterinary students who created the nation's first One Health Center.

 

After graduating, she returned home to the Riverside area and began working for a small animal general practice hospital for almost four years, where she enjoyed the challenge of surgery and internal medicine cases.

 

She then joined the Back to Health team in 2020 to help those pets that are in pain, and give them a better quality of life – especially when medications are just not enough to make them feel comfortable.

 

Dr. Contreras is fluent in Spanish and enjoys practicing the language as much as possible. Her passions outside of the veterinary field include spending time with her friends and family, training her cat, woodworking, traveling, crafting in general, and following her favorite baseball team.
