Dr. Erik Natkin, DO

Medical Director and Provider

Dr. Natkin, although not a true Colorado native, has lived off-and-on in the Denver area since 1987. He was born in California and moved to Germany with his family at the age of 11 when his father, a Psychiatrist, re-enlisted with our Armed Forces. After completing 6 grade through first year of college in Germany he moved to Boulder, Colorado to pursue college at the University of Colorado.

After an eclectic career including environmental chemistry, owner/operator of a small construction-contractor company, and computer information technology he eventually returned to his earlier pursuit of medicine and moved to Los Angeles, California for medical school. He then spent a year in Denver, Colorado completing a year of general surgery and then to Oregon for orthopedic surgery residency training. Upon leaving Oregon he has focused his medical career on the treatment of patient pain management needs which has led him into a the world of Health and Wellness and Regenerative Medicine. His diverse background in life and medical education have suited his patients with a pleasurable and satisfying medical experience.

When not at work and attending to his patients needs, Dr. Natkin is an avid cyclist and enjoys cycling, snowboarading, scuba diving, music, movies, theater and art, travel, and a good book.

Tami Lowisz Medical Assistant in r2 medical clinic

Tami Lowisz

Medical Assistant

Tami Lowisz was born and raised in Chicago, Illinois (Northern Suburbs). She attended College and received her Associates Degree in Liberal Arts. She worked for Discover Financial Services, INC Headquarters for 10 years as a Technical Writer, before she and her two young boys decided to move to Castle Rock, Colorado in 2005. She’s always loved and hoped to return to the mountains, since living in Scottsdale, Arizona from 1990-1997. Moving to Colorado was the best move she feels she could have made, for many unknown reasons at the time.

In her spare time, Tami enjoys spending time with her two teenage sons. She likes to keep busy with cooking, boating, dirt bike riding/motorcycling (passenger, NOT driver), country line dancing, music, occasional weekend get-aways, and a good movie!
