When Symptoms Don’t Follow a Clear Pattern

you deserve providers who believe your symptoms are real.

Do you feel like your body reacts in ways that do not fit a clear or expected pattern? You may be dealing with digestive symptoms, skin reactions, flushing, food sensitivities, headaches, fatigue, dizziness, or allergic-type responses that seem to affect multiple body systems at once.

If you suspect a mast cell disorder, or you have already been diagnosed, you deserve care that takes your symptoms seriously and understands how to look at the full picture.

Our Approach to Mast Cell Disorders

MCAS can affect multiple systems at once. We support both symptom stabilization and deeper evaluation of immune signaling, digestive health, nervous system regulation, environmental triggers, and overlapping conditions.

Our approach is individualized. We review prior records, evaluate patterns, and determine appropriate testing and referrals when needed. If you regularly find treatments cause a reaction, we pace care carefully and prioritize what your body can tolerate.

What Makes Our Digestive Care Different

01

Extended Visits

We offer 90-minute new patient visits and 30–60 minute follow-ups, allowing time to understand complex histories and create more individualized care plans

02

Careful Pacing

Treatment is introduced step-by-step based on your tolerance, allowing your body to adjust without overwhelm.

03

Specialized Expertise

Our providers bring advanced training and a wide range of treatment tools, allowing us to support both symptom relief and deeper root-cause work over time.

What You May Notice Over Time —

  • Fewer or more manageable flares

  • Improved baseline stability

  • Better understanding of triggers

  • A clearer, more personalized treatment plan

  • Ongoing support from a provider who understands complexity

Care That Adapts to Your Life
—

Many people with MCAS have tried treatments that felt too aggressive or destabilizing. We take a different approach. An approach that prioritizes tolerance, flexibility, and ongoing reassessment.

  • Generally no. Patients can most often self refer. There are times where if you have been working with another provider extensively on your conditions where a referral can be supportive just to have the full clinical context of why you are establishing care and medical records included in the referral. It is not required to have this to establish though. 

  • No! We do encourage everyone having a primary care provider. Many of our specialist care providers can also provide primary care and if they cannot they can also support you in finding the right primary care provider if you are in need of one.

  • No, we are out of network however we can provide superbills upon request.

  • No, we work with people in many phases of work up and exploration of symptoms. Our clinicians can work with you through a diagnosis process if you do not yet have that prior to establishing care.

  • MCAS is a condition in which mast cells release inflammatory chemicals (such as histamine) inappropriately or excessively. This can cause symptoms affecting multiple body systems, including the skin, gastrointestinal tract, cardiovascular system, and nervous system.

  • There is no single test for MCAS. Diagnosis typically involves:

    1. A detailed medical history and symptom review

    2. Evidence of symptoms affecting multiple body systems

    3. Response to mast cell–targeted treatment

    4. Lab testing for mast cell mediators (when appropriate)

    5. Referral to gastroenterology for specific biopsies that can indicate MCAS when positive 

    6. We take a comprehensive and individualized approach to evaluation.

  • Yes. MCAS can overlap with conditions such as:

    1. Postural Orthostatic Tachycardia Syndrome (POTS)

    2. Hypermobile Ehlers-Danlos Syndrome (hEDS)

    3. Long COVID

    4. We evaluate patients holistically and coordinate care as appropriate.

  • Every patient is different. Some individuals notice improvement within weeks, while others require longer-term care to stabilize symptoms. Our goal is steady, sustainable progress.
