Dr. Katcher will be leaving Esse Health


Dr. Jeremy Katcher, MD

will be leaving Esse Health Gateway Asthma & Allergy as of December 31, 2022. He will be joining Washington University Allergy/Immunology with locations in Creve Coeur and St. Louis Highlands – in the Central West End. If you wish to continue seeing Dr. Katcher, you may call 314-996-8670 to schedule your follow-up appointment, request medication refills, or ask general medical questions.

Patients receiving allergy shots at the Esse Health Washington Family Medicine Heritage Hills location may continue receiving allergy shots at that location, and your care will be transferred to Dr. Katcher’s partner, Dr. William Johnson. For those patients, there is nothing you need to do. Your follow-up visits will continue with Dr. Johnson and his present staff at the Esse Health Gateway Asthma & Allergy office on Tesson Ferry.

Patients presently receiving their allergy shots at the Tesson Ferry office may continue to receive shots at that office. Your care will be transferred to Dr. Johnson and his present staff.

We apologize for the inconvenience that this change may cause. Please feel free to call the office at 314-421-0663 with any questions.


We love taking care of our patients.  We want your visits and our care between visits to be as helpful and effective as possible, so we strive for excellence in our communications and attention to detail.

Our Telemedicine Option

Contact us by phone to set up a follow-up appointment and ask about the Telehealth option.  If appropriate, we will schedule a Telehealth visit using our Noteworth Connect app.  You may download and register for the App after which you will be guided through the process leading up to your virtual visit with one of our doctors.

Allergy Testing

Testing is often a key step in crafting your treatment plan.  We start with safe and simple skin testing to identify your allergies.  We add advice on environmental control measures and use of appropriate medications.  We discuss further options including desensitization procedures.


Conditions We Treat:

  • Pediatric and Adult Asthma
  • Pediatric and Adult Allergy
  • Food Allergy
  • Drug/Medication Allergy
  • Hives/swelling and Histamine related disorders
  • Immunodeficiency evaluations
  • Atopic Dermatitis (Eczema)
  • Contact Dermatitis Testing and Treatment
  • Penicillin Drug Allergy Testing
  • Peanut Oral Immunotherapy (desensitization)
  • Airborne Allergen Immunotherapy (aka Allergy Shots)

efficient, cost-conscious, responsible, and trustworthy

Words we work and aspire to maintain.  For most patients, we are the first and only necessary step in discovering their potential allergies, controlling their environment, and crafting a plan of action to treat symptoms and prevent disease.  We invest heavily in one-on-one conversation with you at the initial and subsequent visits so we don't miss your main concerns.  We want you to be part of the treatment strategy and planning, to equip you with the necessary information and options, and together formulate a working solution to the problem.


Next Steps...

When you're ready, just give us a call.  We can usually see you without a referral.   We reserve multiple openings in the schedule daily for new patients and can usually make an appointment for you within a couple of weeks.  We will often perform the consult and testing on the same day to save you time and money, and have you on your way with a plan of treatment after the first visit.

Time and committment

We want you well ... is our slogan, and we have found that the best way to maintain that commitment to you is by investing time in the relationship, not just while you visit the office, but in between.

Electronic Communications

Up to date communications with easy telephone access, text messaging, voicemail, and email via the patient portal for private matters, or comments and general questions through our website and Facebook accounts.

Electronic Health Records

By being part of a larger group (Esse Health), we are able to invest in technology that enhances patient care and allows us to be responsive to your changing needs.  We are constantly updating, securing, and improving the way we collect and maintain your valuable information.

Next Steps...

We can usually see you with or without a referral from your primary care provider as most insurances allow you to simply call for an appointment.  Call or email us and we'll get you scheduled.
