🌿 Mast Cell Activation Syndrome (MCAS) Specialist in Washington
In-Person Appointments in Bellingham, WA + Telehealth Across Washington State
Mast Cell Activation Syndrome (MCAS) can cause a confusing mix of symptoms—flushing, fatigue, stomach upset, rashes, dizziness, headaches, chemical sensitivities, and unexplained allergic-type reactions. Many patients spend years searching for answers.
At Galene Health, MCAS is approached with compassion, clarity, and evidence-based care. You receive thoughtful evaluation, symptom mapping, and a personalized stabilization plan from a provider who understands the complexity of mast cell disorders and their overlap with autonomic dysfunction.
I’m Katherine Bachenberg, DNP, AG-ACNP, and I provide specialized MCAS care in person in Bellingham and via telehealth for patients throughout Washington State.

🌿 What Is MCAS?
Mast cells are immune cells involved in inflammation, allergic reactions, and cellular signaling. In MCAS, these cells release mediators inappropriately or excessively, causing widespread, fluctuating symptoms that often appear unrelated.
MCAS frequently overlaps with:
-
POTS
-
Dysautonomia
-
EDS (Ehlers-Danlos Syndrome)
-
Chronic fatigue syndromes
-
Long COVID
-
Chemical or environmental sensitivities
Understanding these connections helps create a calmer, more stable daily life.
