The Joint Chiropractic - McCarthy Ranch

Jonathan was born in western Wisconsin and was raised in the rolling farmlands of the Mississippi Valley. Due to a nearly fatal struggle in infancy to grow and develop, Jonathan was taken to a chiropractor out of desperation who succeeded in restoring his body’s natural function and ability to thrive, saving his life. Years later, as a child, Jonathan began to suffer from seasonal allergies and severe migraine headaches, which were treated with steroids and painkillers. Once in high school, after a decade of suffering, he visited the local chiropractor, who once again restored his body’s natural function, permanently resolving both the allergies and the migraines. This was a life-changer for Jonathan, who was now able to participate more successfully in everything from athletics to art to educational pursuits, earning high honors in martial arts, music, theater, public speaking and the basic sciences.

Jonathan decided to become a chiropractor so he could perform the same service for countless others; reducing suffering and unlocking potential. He first studied human biology, physics and chemistry at the University of Wisconsin in La Crosse, and studied psychology and philosophy at Philipps Universität in Marburg, Germany. Jonathan enrolled in chiropractic graduate studies at Northwestern Health Sciences University in Minneapolis, Minnesota, where he completed his Bachelor of Science degree in Human Biology, and where in 2014 Jonathan earned his Doctor of Chiropractic degree.

Upon graduation, Dr. McCune was offered to run a mentor’s practice in Lima, Perú. Despite not speaking Spanish at the time, he accepted the job, moved to Peru, and hired a local interpreter named Diana Ramos. Over the following three years, Diana saw so many lives dramatically change under Dr. McCune’s natural care that she decided to devote herself to the profession as well. She earned a scholarship to Life West in Hayward where she and Dr McCune are living, now happily engaged, as she completes the Doctor of Chiropractic program. This is what brings Dr. McCune to the Joint and to you!

Dr. Weltchek is a licensed chiropractor who graduated from Palmer College of Chiropractic West in San Jose in 2002. After graduating, he worked for several private practices in Salinas, CA for three years before moving on to a private practice in Santa Cruz, CA for the next sixteen years. In November of 2021 he joined The Joint Chiropractic as a Clinic Chiropractor.

His goal is to help his patients achieve optimal health, form, and function by finding and correcting the root cause of the problem thus restoring the structural integrity and mobility of the spine while at the same time reducing the pressure on sensitive and vital neurological tissues. Dr. Weltchek is also a big proponent of regular/routine maintenance/wellness care to keep the body "tuned-up" and functioning at its maximum potential.
