Staff Information

Robert C. Stelzle MD FACAAI

Dr. Stelzle trained in Pediatric & Adult Allergy/Immunology through a two year Fellowship Program at Walter Reed Army Medical Center in Washington DC from in the late 1990s.
After fellowship, he moved to Ft. Gordon Army Medical Center in Augusta, GA to run their Allergy/Immunology Clinic for a couple of years before moving to Rapid City in 2001.  Since 2001, he continues to provide patient care in Allergy/Immunology to those in Rapid City and the surrounding region.
Before studying Allergy/Immunology, Dr. Stelzle had previously completed a three year Internal Medicine Residency at Fitzsimons Army Medical Hospital in the early 1990s.  

After this Internal Medicine Residency, but before A/I fellowship, he practiced as an Army Internist, serving his country overseas -- while paying the Army back in "time" for the scholarship that they provided for him to attend medical school.
Dr Stelzle is currently the only "West River" Allergists/Immunologists in SD who is actually certified by the 'American Board of Allergy & Immunology" (ABAI).   Dr Stelzle is also the only "West River" Fellowship-Trained Allergist/Immunologist at this time. (see explanation below re: ABAI) 
Dr. Stelzle considers himself as more of a "rural" specialist than a "national expert" in Allergy/Immunology.  He certainly doesn't know everything about this complex area of medicine.  However, he studies hard to try and keep up with the most current advances in this field in order to provide the best possible care for his patients.  His academic efforts resulted in him reaching the 98th percentile (ie: top 2%) on his initial ABAI board exam, shortly after graduating from fellowship.   Since then he has continued his lifelong learning efforts, and a decade later, "re-certificated" with the ABAI for another 10 years.
Dr. Stelzle's main desire is to try to use what he has learned to help others.  Given the time limitations during a busy clinic day, he tries to delegate part of the teaching process to his very well trained nursing staff.  He also hopes that the educational material on this website furthers that goal -- helping patients achieve excellent allergy, asthma and immunology control.
ENT Surgeons (Otolaryngologists), Family Practice Physicians, Internal Medicine (Internists or Hospitalists) Doctors & Pediatricians have their own residency programs, and prestigious certifying board organizations, but they are not ABAI certified (or even eligible to sit for the ABAI certifying exam, since they haven't completed an allergy/immunology fellowship program).
Links of Possible Interest:   ABAI    ACAAI    RCRH     AAAAI*
* Although Dr. Stelzle is no longer an AAAAI member because it is so very similar (and redundant) to the ACAAI (to which he belongs), he still thinks the AAAAI is an excellent organization.  The AAAAI's website  is similar to the ACAAI's site and has a wealth of trusted information.  Dr. Stelzle endorses the AAAAI to the fullest and highly encourages that you visit their website to learn more about your allergic condition.

Dr Khan's Transition

We regret to inform you that Dr Khan has finished up her time at AABH and has moved from the area.  

While Dr Stelzle and the AABH staff will dearly miss her, we are very happy for Dr Khan as she moves on to explore new exciting opportunities.

At this point in time, Dr Stelzle will be taking her place -- and will be happy to serve all of Dr Khan's patients.

Best Wishes to Dr Khan!!!...

   ....and a big Thank You for all of your dedication, hard work, and service to AABH and all of our patients!

Our AABH Team:

Lisa Uhre LPN
Lisa has been with AABH since 2006.  She serves as the chief/head nurse at AABH.  She is a hard worker and strives to serve her patients at the highest level of care.

Lisa basically runs the clinical side of our operation.  She orders supplies, gets extracts ready, interacts w/ patients, vendors, insurance companies, pharmacies, and others.  Lisa has trained all the other nurses at AABH, drawing on her years of experience.

She his a true patient advocate and clearly a critical member of our team.  AABH, and our patients, are very lucky to have Lisa working on our behalf.
Chris Sewell MA

How nice to find a young energetic nurse who loves her job and wants to share her caring and concern with those in need.  

Chris came to us in the in the Spring of of 2016, and quickly jumped in to fill the shoes of Catrina and Trish - both of whom still help us out prn but have other obligations which prevent them from working regular shifts.

We know how much we appreciate Chris, and know that you, our patients, will enjoy getting to know genuine and compassionate personality as she strives to care for you over time.

Gladys Hartl
Gladys has been with AABH almost since its inception in 2002.  She runs the clinic in terms of all the nonclinical duties.  This is a daunting task but she does it with calm, composure and efficiency.  She's the friendly face at the reception desk, the one who does the medical billing, the scheduler of appointments, the one you call when you have questions.  She performs many other front and back office operations that go unseen.
Because we are a fairly small clinic, Gladys literally does the individual jobs that multiple workers would do in a larger clinic.  She has worked hard over the years to learn all these different clinic duties and is a great resource for our patients given her extensive experience and knowledge all these areas.
Gladys is a humble but hard working member of the AABH team who comes to work every day to serve you and AABH.  We are very grateful to have her as part of the AABH family.

Mary Moss

Mary is a new Receptionist/Biller who has just joined us in Summer 2015.  

Those of you who have reception experience know how crazy it can become at the front desk of a small business. 

Although Mary is only here part time, she has proved to be an incredible asset at our front desk, relieving Gladys of some of her sometimes overwhelming duties.  We are very grateful for all you do Mary!

Catrina Engesser LPN prn

Catrina is a wonderful new addition to our AABH Staff as of January 2016. 

We are all amazed how quickly Catrina has caught on with her new allergy nurse job duties.  After just a couple weeks, it seems like she's been here for years.  She is a very quick learner has already mastered almost all of our allergy nursing procedures.

Although she has many other obligations currently, we are still very fortunate to have her on our list to call on an as needed basis -- a role, that given her many talents, she can easily slip back into without difficulty.   She is an easy going, very likable, individual who is sure to make you feel at home.  

Trisha Krull MA prn

Trish is now a seasoned veteran of our AABH staff.  She brings a wealth of past experiences to help us continue to improve our clinic efficiency and patient care.  

She has worked as an emergency room technician, pediatrics medical assistant, cardiac study research staffer and Airman experiences with the Air Force in the USA, Africa, Afghanistan, and Kuwait.

Trish is a very fast learner and dedicated to expanding her medical knowledge base.  She is currently busy, enrolled in a well respected 4 year RN program here in RC but still finds time to help us on a prn / part time basis.  

We are very grateful to Trish for helping us keep our small clinic going when short-staffing situations unexpectedly arise.  Thank you so much Trish!
