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.

These experiences inspired Dr. Tiu to pursue a career in vascular surgery. Dr. Tiu thinks vascular surgery is the most interesting field of medicine.

The surgeon’s more cosmetic approach also offers less pain and a quicker return to a happier and more productive lifestyle.

Dr. Essien also performs laparoscopic sleeve gastrectomy, laparoscopic gastric bypass, and revision bariatric procedures.

With a passion for Bariatric surgery, Dr. Essien helps patients achieve their goals of a healthier weight while eliminating the medical illnesses associated with excessive weight and enjoying a better quality of life.

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.

 

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.

Thank you for choosing Murrieta Valley Surgery Associates, looking forward to the opportunity to help you in your wellness journey
