Zintis was born in Kalamazoo Michigan to Latvian emigrant parents. He was raised in a household filled with love, art, culture and spiritual openness. During his late childhood and as an adolescent, he widely explored the metaphysical and channeled literature that was available at the time. He was especially influenced by the Seth Books as channeled by Jane Roberts.

Zintis was fortunate to live in West Germany in the 1970's and in Denver, Colorado in the 1980's. In 1987 he moved to New York City. During his time there, he was trained to be a Reiki healer, and also became familiar with many other forms of energy healing and bodywork. Among these are polarity healing, pranic healing, shiatsu, therapeutic touch, acupressure, kinesiology, and different forms of massage. In 2003, Zintis became as Reiki master teacher.

Zintis incorporates many of these modalities in his practice. In NYC, Zintis also resumed his yoga practice. Between 1989 and 1994 Zintis worked at Gay Men's Health Crisis, the largest AIDS service organization in the United States.

In 1994 he moved to an old farmhouse in upstate New York, about 2 ½ hours from NYC. He lives simply, heating with wood, preserving food from his gardens, and spending much time in nature communing with the natural elementals.

It was here that Zintis began offering healing sessions on a full-time basis.

In 1997 he started teaching yoga classes, and in 2000 built and opened his yoga studio, the Yoga Barn. Zintis now offers 7 yoga classes a week when in residence in Callicoon. From 1999 to 2006 he has taught annually at the Rio Caliente Spa near Guadalajara, Mexico.

In addition to teaching yoga classes, Zintis sees about 15 clients for private sessions every week — the format depending on the needs of the client. Some come for energy healing, some for hands-on intuitive massage, and others for private yoga instruction.

Since 2002, he has expanded his work to London, England; Riga, Latvia; Chicago, Illinois and other locations.

Zintis is also an ardent organic gardener, growing cut flowers for sale during the summer months and growing and putting up most of his own food.

A priority for Zintis is continuing to spend time tending his lush gardens every day. A side business which he particularly enjoys is raising and selling flowers from his gardens. Visitors to his house and studio often enjoy spending time in the gardens, with the views from the Yoga Barn particularly relaxing.
