Pioneer in Functional & Integrative Medicine Since 1976

About Meridian Valley Lab

Meridian Valley Lab has been a pioneer in functional and integrative medicine since 1976. We were the first lab in the U.S. to offer urine hormone testing, revolutionizing the way providers approach Bio-identical Hormone Replacement Therapy (BHRT). This breakthrough came from the vision of Dr. Jonathan Wright, our Medical Director, whose work continues to inspire innovation and clinical excellence.
