Family Physician Temecula
Dr. Poste Bio
Dr. Poste grew up in San Pedro, CA, where she began her journey in the field of medicine. She attended California State University Long Beach before continuing her education at the Universidad Autónoma de Guadalajara School of Medicine and New York Medical College, where she further honed her medical expertise.
Her passion for medicine was sparked when her grandfather became seriously ill. As his English translator during hospital visits, Dr. Poste observed the deep respect he had for his doctors, which inspired her to pursue a career in medicine. Motivated by her supportive family, she set her sights on providing hands-on patient care and making a meaningful impact on the well-being of others.
Outside of her practice, Dr. Poste enjoys spending quality time with her husband, two children, and their cat and dog. She loves traveling and immersing herself in different cultures and languages, being fluent in English, Spanish, and Italian. To stay active and healthy, she enjoys working out on her Peloton.
