Our Services

At Advanced Allergy, Immunology & Asthma, our goal is to provide clarity, relief, and long-term wellness to patients who have often struggled to find answers.

 

We offer expert, patient-centered care under the guidance of Dr. Denis Bouboulis, a board-certified allergist and immunologist with over 25 years of clinical experience, and recognized for his work in diagnosing and treating complex immunologic and tick-borne illnesses.

White Background

Immunology & Autoimmune Conditions

Autoimmune disorders and immune dysfunctions can trigger a range of difficult and recurring symptoms. Dr. Bouboulis and the Advanced Allergy team specialize in identifying root causes, especially in patients who haven’t found answers elsewhere.

 

Conditions We Evaluate & Treat:

  • Common Variable Immune Deficiency (CVID)

  • Recurrent or unexplained infections

  • Chronic inflammatory or immune-related symptoms

  • Conditions related to immune dysregulation, including pediatric neuroimmune syndromes

PANDAS/PANS – Pediatric Autoimmune Care

Children facing PANDAS/PANS need specialized care to address sudden-onset behavioral and neurological symptoms. Dr. Bouboulis provides compassionate and expert evaluation to guide families through diagnosis and treatment.

  • Obsessive-compulsive behaviors

  • Motor tics and anxiety

  • Sensory disturbances

  • Academic regression

Lyme Disease and Vector-Borne Disease Analysis

Vector-borne illnesses like Lyme disease and Bartonella can have serious long-term effects if undiagnosed.

 

Dr. Bouboulis and our team provide advanced diagnostics and integrative treatments to help patients regain health and energy:

  • Lyme Disease (Borrelia)

  • Bartonellosis (BART Analysis)

  • Ehrlichiosis / AnaplasmosisBabesia & co-infections

Plasma Exchange (Plasmapheresis)

For patients with severe autoimmune neurological disorders, plasma exchange offers a powerful intervention to remove harmful antibodies and reset immune function. Dr. Bouboulis and our team provide coordinated plasma exchange services for complex cases that haven't responded to conventional treatments.

​

Plasma exchange involves filtering the patient's blood to remove plasma containing autoantibodies, replacing it with albumin or donor plasma.

 

This procedure is particularly effective when combined with IVIG therapy for conditions involving immune dysregulation.

 

Conditions We Treat with Plasma Exchange:

 - Autoimmune Encephalitis
- Severe PANDAS/PANS cases
- Treatment-resistant Lyme disease with neurological symptoms
- Myasthenia Gravis
- Guillain-Barré Syndrome
- Complex neuroimmune disorders

BART Analysis – Bartonellosis Evaluation

Bartonella is a persistent and often overlooked infection. The Advanced Allergy team uses leading-edge testing to identify Bartonella’s presence and its impact on the brain, heart, and immune system.

  • DNA/PCR testing

  • Western blot / Immunoblot panels

  • Neurocognitive evaluations

  • Comprehensive co-infection profiling
