Welcome to our Website

At the American College of Allergy Asthma and Immunology annual meeting in Atlanta last November, I was inducted into the Board of Regents.  Three allergists were chosen nationally for a 3 year term to lead this organization, dedicated to the practicing allergists and their patients.  It is with great appreciation to my mentors, my staff, my colleagues, and my patients that I step up to this national leadership position.

But, most importantly, we continue to dedicate ourselves to our patients with state of the art care that we continue to refine.  My associate, Dr Diane Napoli, has introduced drug desensitization and oral food challenges to our practice, and is at the top of her game after an illustrious 20 year career in the US Air Force, with continuing full commitment to her patients. 

So, for all your allergy, asthma, and immunology healthcare needs, we are here for you, dedicated to the finest quality, evidence based, creative, and cost effective care possible.

My staff and I wish you good health.

And remember, we want you to.... "Breathe Easy"!

Spring is Here....and So is the Pollen

Spring is that time of year that we all look forward to, but for all of its beauty, it can make people with seasonal allergic rhinitis (hay fever) miserable.  Hay fever is most often caused by pollen in the air.  Pollen is the fertilizing agent of trees, grass, weeds and flowering plants. Pollen is the major substance (allergen) that causes symptoms of seasonal allergic rhinitis.

Symptoms include:

  • Runny nose
  • Itchy,watery eyes
  • Chronic nasal congestion and snoring
  • Itchy roof of the mouth or throat
  • Frequent sneezing
  • Dark circles under the eyes

For people who suffer from allergic rhinitis, being aware of the current pollen levels can help them manage symptoms.  Pollen levels are greatly impacted by current weather conditions. Pollen are very small and, as a result, are very easily kept airborne and moved over long distances on windy days. We've all seen it....... covering a car like a yellow blanket or flying through the air just over our heads.   Rain and humidity, results in the pollen becoming damp and heavy, and therefore, it stays on the ground.  For this reason, people who suffer from allergic rhinitis feel better on rainy days and people have increased allergy symptoms on windy days. 

One of the first steps in managing this condition is to limit the exposure to the allergens that cause symptons.   Sometimes limiting exposure to allergens isn't enough to control symptoms and  it can greatly impact one's freedom to enjoy the outdoors.  This is when an allergist may recommend certain medications to better control symptoms or may suggest allergy immunotherapy, also know as allergy shots and tablets.   Medications can often help control symptoms, but allergy immunotherapy  treats the problem and not just the symptom, and has been proven to be effective for over 100 years. 

If you are suffering from seasonal allergies our allergists are here to help you and will recommend a personalized treatment plan for you based on their evaluation of you and your personal goals.  We want our patients to enjoy our Colorado!

News You Can Use


Flu Shots Are Available Now At Our Office For Our Patients. 
No appointment is needed; flu shots will be given during our regular shot hours.  Patients cannot receive an allergy shot and a flu shot on the same day. 

Influenza is a serious illness. The Centers for Disease Control and Prevention (CDC), along with leading health experts, recommend that everyone 6 months and up receive an annual flu shot. The annual flu shot is a safe and effective way to help protect yourself from the flu.   Vaccines are especially important for people with asthma.  Certain diseases that can be very serious for asthma patients can be prevented with vaccines.  Please talk with our doctors.

Do You Know the Right Way to Cover Your Cough?

Using your hand to cover your cough is considered a big no-no. Be a good flu fighter and always cough or sneeze into the elbow or use a tissue.  Avoid touching your eyes, nose or mouth and wash your hands with soap and water often.  Teach your kids to be good flu fighters too.


How Can We Help You?

  Nasal/Environmental Allergies
Nasal allergies may also be referred to as hay fever or allergic rhinitis.  This is an allergic reaction to elements in the environment, such as tree, grass and weed pollens, pet dander, molds and cockroaches. Individuals that are allergic to pollens may only be symptomatic  at certain times of the year.  People allergic to indoor allergens, such as mold, may experience symptoms all the time.  Click here to read more.
Asthma is a chronic lung disease in which the lining of the airways becomes inflamed and swollen and muscle spasms restrict the flow of air to the lungs.  It is a relatively common condition and the incidence of the disease has grown in recent years.   Currently, it is estimated that close to 15 million Americans have asthma.   Children account for a significant
portion of asthmatics.  Asthmatic and allergic disorders rank at the top of childhood diseases. Click here to read more.
  Animal Allergies  
Pets can cause problems to allergic patients in several ways. Their dander, or skin flakes, as well as their saliva and urine, can cause an allergic reaction. The animal hair is not considered to be an allergen as many people believe. However, the hair or fur can collect pollen, dust, mold and other allergens which can cause additional allergic reactions. Click here to read more.
