How We Started

Tandem Wellness Center, LLC began as an individual private practice in 2001. In 2013, the private practice of Dianna Sandoval, LPC, LAC expanded to Tandem Wellness Center, LLC. The program grew from providing individual therapy services with one provider to offering counseling, nutritional coaching, and trauma release through therapeutic massage.

Growing from one staff person to 10 staff, in 2015, the founder of Tandem Wellness Center, LLC partnered with two individuals to cofound a treatment program called Sandstone Care. This program provides mental health and substance abuse services to adolescents, young adults and families.

Tandem Wellness Center, LLC was scaled back to a private practice model for the past 4 ½ years. We are excited to ramp up and re-kindle the program with new and innovative services in mental health, addictions, and organizational coaching on program development and organizational culture.

In this new chapter we will be offering outpatient services, individual, couples, and family counseling, integrative services with nutritional, experiential, and eclectic treatment approaches to ensure individualized care. Tandem Wellness Center, LLC is a faith-based program. The program is built on loving, accepting, and serving all of God’s people whether they are faith based or not.
