A Message From Dr. DelasAlas Allergy & Asthma Center of Duncanville

Growing up in Texas, I experienced the challenges of severe seasonal allergies firsthand, often avoiding beautiful afternoons outdoors to prevent feeling miserable for the rest of the day. Watching friends and family struggle with their allergy and asthma symptoms, usually finding little relief from over-the-counter remedies, fueled my passion for helping others overcome these challenges.Today, I feel incredibly blessed to work with an amazing and talented group of individuals who genuinely care about your health. I am dedicated to helping you and your family live healthier, happier lives. Our team is committed to providing compassionate care and is trained and equipped to offer the most advanced treatments. We combine cutting-edge options like biologicals with immunotherapy to effectively treat asthma, hives, eczema, and food allergies.Our patients are often amazed by the effort we put into education, empowering them to better understand their medical conditions and get the most out of their medications. We believe that informed patients are better equipped to take control of their health, which is why patient education is at the heart of our care.We take pride in that many of our new patients come to us through referrals from friends and family members who have already benefited from our personalized allergy care. We understand how unexpected allergy flares can disrupt your life, and we work hard to accommodate same-day sick visits, helping you regain control, manage symptoms, and focus on what matters most to you.For those unfamiliar with options like “allergy shots” or advanced biologics, we’re here to share how these treatments can transform your quality of life, offering greater control than medications alone. Parents are often surprised to discover how undiagnosed allergies can contribute to frequent colds or recurring illnesses in their children. Addressing these root causes, we help families achieve a healthier, more fulfilling life together.
