Dr. LaCoss

N.M.D.
Dr. LaCoss N.M.D.
Dr. LaCoss completed her undergraduate education in 2006 at Carroll College in Waukesha, Wisconsin, where she earned her Bachelor of Science with a major in Human Biology. As part of her studies at Carroll College, Dr. LaCoss initiated her own research project that looked at the effects of acute and chronic stress on the body. After graduating from Carroll College, Dr. LaCoss moved to Arizona to attend the Southwest College of Naturopathic Medicine, where she earned her Doctorate of Naturopathic Medicine in 2010. Although Dr. LaCoss originally planned on pursuing Women’s Medicine, she became intrigued with Addiction Medicine. During her clinical education at the Southwest College of Naturopathic Medicine, Dr. LaCoss interned at The River Source for a year and a half, worked one on one with Drs. Terranella and Kim, and also worked with Dr. Arneson at his private office. During these experiences Dr. LaCoss learned the importance and effectiveness of using Acupuncture, Nutrition, IV Therapy, Botanical Medicine, and Homeopathy to treat patients who are undergoing drug/alcohol detox and rehabilitation.

Testimonials Dwne erro

"To whom it may concern,   My name is John L. and I came to The River Source because my life was completely out of control. I was running around drinking and using meth. I have been an addict for 23 years, in and out of prison, not caring about anything or anyone. I would only get sober while in jail. I’d lost everything.   I’ve spent a total of 9 ½ years in prison and county jail, on 4 different occasions. I cleaned up every time, with the longest being 4 years...."
