Patient-Facing

Dr. Ashley Southern didn’t start Alturas Medical Weight Loss to run just another clinic. She started it because she was tired of watching patients fail programs that weren’t designed for how the human body actually works.

As a board-certified Naturopathic Medical Doctor with 5+ years of clinical experience, she brings both the science and the empathy that lasting weight loss requires. Her training in regenerative medicine and hormone therapy gave her a deep understanding of how hormones, metabolism, and appetite regulation interact – the foundation for everything Alturas does today.

At Alturas, Dr. Southern oversees every patient’s treatment plan personally. She combines Meridian’s most effective weight loss options, physician-prescribed GLP-1 medications like Semaglutide and Tirzepatide, with targeted hormone therapy for patients whose results have plateaued elsewhere. The result is a program that works when nothing else has.

A Hormone Specialist for Boise and Meridian Patients

Hormone care is the center of Dr. Southern’s practice, not a side service. She prescribes and manages bioidentical hormone replacement therapy for women, testosterone replacement therapy for men, and hormone pellet therapy for both. Every plan starts with a conversation about symptoms, history and goals, and we review lab work before prescribing whenever it is medically appropriate.

Patients come from Boise, Eagle, Nampa, Kuna and Star for a hormone specialist who reads her own labs and adjusts doses herself. Many also pair hormone therapy with GLP-1 weight loss, because the two problems usually arrive together after 40.

“I enjoy getting to know my patients and building meaningful relationships. Weight loss is deeply personal, and people deserve a physician who takes that seriously.”
