Dr. Johanna Lelke, DC

Doctor of Chiropractic, Founder and CEO of Onsight Chiropractic
Dr. Lelke is out on maternity leave, and therefore unavailable for patient care, through August 2020.

The quality of your care depends vitally on your caregiver. Dr. Johanna appreciates the privilege of being that person for you, using her own strength and flexibility to restore yours. Devoted equally to skill and support, she draws her greatest satisfaction from guiding self-healing and informing healthy habits.

Dr. Johanna graduated pre-med from the University of Massachusetts, where she sprinted and leapt her body into strain as a Division One heptathlete and pole vaulter. Hunching over cell culture and molecular biology experiments as a research technician in Massachusetts General Hospital’s neurogenetics lab, the dissonance between tortured posture and love of movement drew her first to chiropractic treatment and then to practice. Climbing New Hampshire’s sheer granite shifted to Oregon’s as she earned her doctorate from the University of Western States, and then to Yosemite when she came to the Bay Area in 2009. Rock climbing, trail running, mountain biking and skiing continue to remind her how crucial joint alignment and muscle release are to balancing the stresses of regular exertion.

Between office visits, you can find Dr. Johanna teaching a weekly yoga class at Bridges Rock Gym, volunteering with triathlon medical staff, or guiding her niece and nephew in the art of rock climbing. Stretch empowers focus, so when you come in, you’ll feel the depth of her attention and the attunement it invites.

Edward Espinoza DC, MS

Doctor of Chiropractic

Eddie was born and raised in Castro Valley, California. He attended Valley Christian High School in Dublin and chose to pursue the path of chiropractic medicine after seeing first hand how his mother benefited tremendously from her treatments of debilitating low back pain. Eventually, he took his studies to California State University Chico where he studied Small Business Management, with his chiropractic dream still in mind.

Eddie then attended the University of Western States in Portland, Oregon and earned his Doctorate of Chiropractic in December 2016. While at Western States, he also earned a Master’s Degree in Sports Medicine. This allowed much more hands-on experience with on-field injuries, rehabilitation, and sports-related injuries. Eddie’s goal in patient care include reducing pain as quickly as possible to regain activity and movement. Movement is life. Every system in the human body depends on movement to stay healthy, whether you are talking about the heart, muscles/joints, and even digestion. Movement directly correlates with one’s quality of life.

Traveling and live music are two of Eddie’s biggest passions outside of patient care. He also enjoys challenging Crossfit workouts, snowboarding, bouldering and watching Bay Area sports. Furthermore, he takes pride in providing athletic training and medical services to Valley Christian Vikings Football team as the on field doctor for home and away games.

Dr. Mykyta ‘Nick’ Predtechensky, DC

Doctor of Chiropractic

Dr. Nick believes that pain-free movement is a fundamental part of living your life to its fullest potential and is dedicated to helping you achieve that goal. Drawing on the science of chiropractic and his experience as a yoga instructor, Dr. Nick aligns with the Onsight team in his dedication to promoting better health.

Born and raised in a family of journalists in the slightly colder country of Ukraine, Dr. Nick emigrated to the United States in 2008 seeking a more liberal and diverse environment. Originally settling in Michigan to study journalism, his plans were interrupted when he came across a unique yoga studio where he witnessed countless people make the journey to better health and well-being. Inspired by the nurturing attitude of yoga he gathered the courage to leave behind the family craft after graduating from Michigan State University with a B.A. in Political Theory and Constitutional Democracy. He moved to California and earned his Doctorate from Palmer West College of Chiropractic. Still deeply influenced by his experience as a yoga instructor, Dr. Nick is committed to helping you reconnect with your body.

Right now, Dr. Nick is working on completing his Neurology Diplomate that qualifies him to better help concussion patients and various other conditions. When not sitting behind neurology textbooks, Nick spends his free time either dancing salsa in San Francisco or going on runs around lake Merritt, always feeling blessed to spread the benefits of chiropractic to our East Bay community.
