Our Story: The Journey of Pioneer Valley Allergy
Before Pioneer Valley Allergy: A Decade of Collaboration
Long before our doors officially opened, our team shared a deep-rooted history. For over ten years, we worked side by side, serving patients across the Pioneer Valley. Together, we built not just professional experience, but lasting relationships within our community.
Grounded in Experience and Compassion
Each of our providers brings specialized training and credentials in asthma and allergy care. But what truly sets us apart is our shared commitment to understanding the unique needs of Pioneer Valley families — because it’s our home, too.
2025 — The Vision Takes Shape
Dr. Vanessa Van Stee, an allergy and immunology specialist with a passion for patient-centered care, founded Pioneer Valley Allergy with one clear goal: to bring modern, dedicated allergy and asthma care to the heart of our community.
July 2025 — Our Digital Home Launches
In July 2025, the launch of our website marked a major milestone for our new practice — our first step into introducing Pioneer Valley Allergy to the region. It was the beginning of something special: a place where people could learn, connect, and find care they could trust.
Today — Thriving and Growing Together
Since our launch, Pioneer Valley Allergy has grown alongside our patients. We continue to expand our reach, offering advanced treatments while keeping our focus on the people and community that make our work meaningful.
Our Founder
Vanessa Van Stee, M.D.
Allergy & Immunology/Board Certified
Dr. Vanessa Van Stee brings over sixteen years of experience in Allergy and Immunology to the Pioneer Valley community. Before founding Pioneer Valley Allergy, she provided dedicated care to patients throughout western Massachusetts, including many years serving the communities of Westfield and Greenfield.
Dr. Van Stee’s educational path reflects her deep commitment to both science and patient care. She earned her Bachelor of Science in Bioengineering from Walla Walla College, followed by a Master of Science in Biomedical Engineering from the University of Memphis. She went on to obtain her Doctor of Medicine from Loma Linda University School of Medicine, completed her Internal Medicine internship and residency at Baystate Medical Center in Springfield, Massachusetts, and pursued advanced training through a Fellowship in Allergy and Immunology at the University of Medicine and Dentistry of New Jersey.
Throughout her career, Dr. Van Stee has been known for her thoughtful, evidence-based approach to managing allergies, asthma, and immune disorders. She believes effective care begins with listening — taking time to understand each patient’s story and providing solutions that fit their life.
Outside of her practice, Dr. Van Stee enjoys exploring the scenic beauty of western Massachusetts and staying involved in the community she’s proud to call home.
