Brian Tiu, MD, is a board-certified vascular surgeon at Murrieta Valley Surgery Associates.

Dr. Tiu always knew he wanted to be a doctor. Growing up, he volunteered at various hospitals and medical centers, which spurred his interest in medicine.

Dr. Tiu studied at Rutgers New Jersey Medical School in Newark, earning his medical degree. Then, he completed a surgical residency at the State University of New York (SUNY) Downstate Medical Center in Brooklyn and a vascular surgery fellowship at Maimonides Medical Center, also in Brooklyn. 

These experiences inspired Dr. Tiu to pursue a career in vascular surgery. Dr. Tiu thinks vascular surgery is the most interesting field of medicine. As an expert in the field, he does everything from minimally invasive procedures, like angiograms, to open procedures, like removing blockages and performing bypasses.

Dr. Tiu loves making a difference in his patients' lives. He never rushes appointments and makes time to explain each vascular diagnosis in-depth. Specifically, he explains the natural course of diseases, including where they originate, why they occur, and what can be done to improve them.

I am Dr. Kaylene Barrera, and it my absolute pleasure to be a surgeon in this community. I grew up in Southern California and got interested in Medicine when I was young. My mother had initially wanted to be a social worker, but then went back to school to become a nurse and would ask me to help her study by quizzing her with flashcards.

This led me to college at the University of California, Irvine and medical school at the University of Southern California, where I was fortunate to work with some amazing mentors that inspired me to go into surgery.  My surgical training continued at the State University of New York, Downstate in Brooklyn where I trained at county and university hospitals.  Again, I was blessed to have the most amazing mentors that taught me not only the technical aspects of surgery but the importance of dedication to our patients.  I appreciated how as a surgeon, one could be involved in every aspect of a patient's care, contribute to scientific breakthroughs and be a patient advocate.  Sharing what I have learned and experienced as a surgeon,  I have published 9 peer reviewed publications, 33 national presentations, and four book chapters.  I also have written about impact of meaningful issues such as drug shortage and the opioid epidemic, as these have a profound impact on my patients lives.

I am a triple-board certified surgeon with expertise in general, colorectal and trauma/ critical care surgery. Born and and raised in Brazil, I completed my medical education at the Federal University of Santa Catarina (UFSC).

In high school, my passion for Biology, Math and Physics led me to pursue medicine for its challenging and exciting nature. Working in the operating room, I take great satisfation in promptly addressing my patient's concerns through surgical interventions.

My frequent surgical procedures involve colorectal cancer removal, anorectal surgery (including hemorrhoids and fistulas), and hernia repair. With over two decades of surgical experience in Murrieta and Temecula, I am committed to providing patients with top-notch care and a positive treatment experience. As a Fellow of the American College of Surgeons (FACS) and the American Society of Colon and Rectal Surgeons (FASCRS), I continuously strive to integrate new technologies into my practice. 

Beyond my medical pursuits, I enjoy traveling with my family, watching movies, reading, operating my drone, and capturing aerial photographs.
