Dermatology / Allergy - Appointments

Patients are seen by appointment only.

Appointments are generally Monday through Friday. Please call 303-874-2078 to schedule an appointment with Dr. Messinger, Dr. Gentry or Dr. Rossi. We see patients at our main office in Englewood, CO and at our satellite offices in Parker, CO and Colorado Springs, CO.

NEW PATIENTS – What to expect/bring

Before you arrive – To help us best assess your pet’s skin condition, we ask that you follow these guidelines:

Please do not feed your pet after midnight the night before your pet’s appointment; water is OK.

Please do not bathe your pet for at least 3-4 days before your pet’s appointment.

Please do not apply any topical medications to your pet’s skin for at least 24-48 hours prior to your pet’s appointment. Do not put ear medications or flushes in your pets’ ears the morning of your appointment.

Please arrive 15-20 minutes prior to the scheduled appointment to complete the paperwork for your pet and get checked in.

For your convenience, some of the forms may be downloaded and completed prior to your pet’s appointment.

During the visit

In order to obtain a thorough dermatological history and examination, please plan on spending 1-2 hours during the first visit. In addition, we may ask that you leave your pet with us for several hours so we can collect and evaluate samples and write a report for you and for your veterinarian. We will try to accommodate your schedule so you can go back to work or run errands during this part of the initial exam.

Please make a list of or bring any medications, nutritional supplements, and topical therapies that are currently being used or have been used in the past on your pet. This helps us to know what “pink pill” your pet is/was receiving. We will need to know what diet your pet is being fed. Please do not rely on medical records for this information.

If possible, please bring a copy of your pet’s medical records from his/her veterinarian for us to keep. It is very important that we have this information to provide the best treatment options. It’s always better to be over-prepared for your pet’s appointment.

If you are interested in intradermal allergy testing for your allergic pet, please review the topic “Allergy Testing Preparation” and “Allergy Testing” on this website.

Post Visit

All home care instructions are typed for your convenience.

Many dermatological conditions are not curable. Long term maintenance may be needed.

Our goal is the safest and best therapies for your pet. Often more than one visit may be required to adequately help your pet.

Yearly rechecks are necessary in order to refill prescription medications.

Please do not hesitate to call Dr. Messinger, her associate doctors or their technicians if you have any questions, concerns or comments. Remember that the dermatology department is available Monday through Friday. However, you may call VRCC 24-hours a day, 7 days a week and speak with someone. We have a terrific emergency service that will help answer questions when dermatology is unavailable.


If you find it necessary to change or cancel your appointment, please let us know at least 24-hours in advance by calling 303 874 2078. By contacting us to reschedule or cancel an appointment, we can let other patients have that appointment time. We keep a cancellation list for clients/patients to get in sooner as appointments become available. If you do not show for an appointment and have not called to cancel at least 24 hours in advance, you may be responsible for a cancellation fee.
