Dr. Aslan is a 1988 graduate of LACC.  He was introduced to the Gonstead technique when as a first semester student he asked Dr. Greg Plaugher what he thought of Motion Palpation Institute (MPI) and his response was, “If you want to learn real chiropractic come down to the Gonstead club meeting Thursday night.” Dr. Aslan never looked back. The class was on listings and it just made so much sense. He became president of the club for two trimesters. Dr. Aslan also spent many weekends at Dr. Richard Gohls office marking x-rays and learning adjusting. After graduation Dr. Aslan worked for a chiropractor in NYC who was a diversified guy but they had separate patients. After observing the doctor adjusting many patients, Dr. Aslan naively asked the doctor, “Does everyone have the same problem, because you keep adjusting them all the same way?” Six months later he started his own practice.

Jennifer Zhu, DC
68 Harold Avenue; Suite 101
Santa Clara, CA 95050

Dr. Zhu's path to chiropractic was an unconventional one. She, like many young people, started studies as a pre-med student in UC Irvine in 2001. She had the good fortune to land a coveted internship program where she was able to experience firsthand that the hospital setting was not where people got well, and decided to pivot to holistic healing. She enrolled in Southern California University of Health Sciences in 2005 for their dual graduate program of chiropractic and acupuncture, with the intention of becoming an acupuncturist. It wasn't until she experienced her first Gonstead adjustment a year later that she was able to understand the profound difference a quality adjustment could make. She had no discernable symptoms, but that adjustment made her want to literally skip while walking off the table! It was a testament to how many people may not know they have a problem, and that helping that problem could drastically improve their enjoyment of life. From there, she became voracious in learning the technique, attending every Gonstead seminar available and dropping acupuncture to focus her attention to honing skills (because who wants to be mediocre at two things when they can be great at one thing?). Since then she has gone on mission trips with Dr. Tanaka annually from 2007-2012, and eventually co-founded the Tanaka Chiropractic Missions nonprofit alongside Dr. Randal Johnson and Dr. Justine Rhee. She has had many great mentors along the way, and in 2015 she established her little health oasis called Element Chiropractic Wellness in Santa Clara, CA, where she serves her community today. When she is not working or volunteering, Dr. Zhu stays active by water activities on sunny days, snowboarding in winter, and dancing mambo whenever she can. On quieter days, she enjoys living room dance parties with her husband and two children, perusing farmer's markets, crafting, and bullet journaling.
