S.A.G.E. Holistic Health and Wellness Center

Gabrielle "Gabi" Siguenza

MS, Registered Associate MFT #156247, Registered Associate PCC #19975

Life often brings us to moments of questioning—Who am I? Where do I belong? What truly matters to me? I enjoy helping teens and adults navigate these questions while building stronger connections with themselves and others. Whether you’re struggling with relationships, school, or work, or simply feeling disconnected, therapy can be a grounding space to rediscover your voice and create more meaning in your life.

Meet Gabi

Clients describe me as warm, grounded, and curious. I value authenticity in the therapy room and see my role, not as an expert on your life, but as a fellow traveler—someone who offers compassion and curiosity along the way. I embrace imperfection, humor, and nuance in the therapy room, and I hold space for the full range of human emotions. As a highly sensitive person, I’ve always felt attuned to the “big feelings” of life, and I now see this sensitivity as a strength that allows me to connect deeply with others and support them in finding balance in our vibrant and chaotic world.

Therapy With Me Feels Like

Therapy with me is calm, patient, and flexible—I honor the nonlinear path of healing. Some sessions may bring laughter, others reflection or silence, and many moments may spark new insights that help you feel lighter and more connected. Clients often tell me, “I never thought of it like that,” as we uncover new ways of seeing themselves that allow for deeper self-compassion and humanity.

Frequently Asked Questions

Answers to Common Questions About Our Services

Absolutely. You don’t need to hit rock bottom to benefit from support. Many of our clients come in feeling “stuck,” overwhelmed, or just wanting a safe space to process life. If you’re curious — that’s enough.

We combine evidence-based therapy with holistic support like Reiki, spiritual care, and community education. As a nonprofit, we focus on healing — not hustling. You’re not just a number here.

Our holistic therapists are trained to hold space for you no matter where you fall on the spectrum of religion or spirituality – or absence of it. We have worked with a large number of folx who are recovering from spiritual abuse, religious trauma or who are having a faith crisis, but that doesn’t mean we have to even talk about spirituality/religion at all during your therapy sessions. If it’s important to you, we create the space for you to explore it in our work together.

It means we treat you as a whole person — not just a diagnosis. We look at mental health, emotional wellbeing, nervous system support, and a variety of other holistic approaches including consulting with your other holistic professional team members if you desire.

We currently accept insurance from:

Aetna
Anthem Blue Cross
Blue Shield
Cigna
Kaiser
Optum / United Healthcare
