New patients

Download, complete and bring the new patient paperwork found below to your appointment along with your ID and insurance cards. Remember to bring all medications, lotions and other treatments you have been using.  Our dermatologists can help more effectively if we understand what you have already tried.


A very small number of patients who consistently miss appointments have led to our implementing a “no-show/late cancellation” fee of $50 for appointments that are missed or cancelled within 24 hours of the scheduled appointment time.


How long will we have to wait?

Patient access for appointments is very important to us; we decided some time back that it wasn't right to be proud that we were booked three months out! We've taken ideas and solutions from the tech industry to help you be seen in a timely manner--we can sometimes even see you today!   

We do not overbook our schedules--we value your time as we do our own. We ask that you bring a little understanding and compassion--if another patient has an unexpected or serious problem, or is frail or elderly, you may be delayed if we take a little extra time to care for them.  If you are late to your appointment, everyone else for the rest of the day will also be late.  To help us stay on time, we ask that you are also on time with your new patient paperwork completed (plan to check in for your first appointment 15 minutes before the appointment time).

Please remember to download and complete the new patient paperwork linked below and bring it with you along with your ID and insurance cards.  Remember also to bring all medications, lotions and other treatments you have been using.  


The Bellevue office is in a chic Old Bellevue home that has been carefully converted to a modern dermatology practice. We are steps away from Bellevue Square Mall and the QFC. Our private parking lot behind the building has ample free surface level parking. In Yakima, we are at the Creekside Office Park off of 40th Avenue near West Washington. Again, we have ample, handicapped-accessible parking.




We strongly prefer existing patients utilize the PATIENT PORTAL link to send us secure messages. Existing patients can send questions and feedback directly to the Front Desk or directly to the Dermatologist.  Please note that neither messaging system is monitored for time sensitive issues, and for emergent issues, we encourage you to dial 911 or seek other emergent care.

Remember to download new patient paperwork found under the "Appointments" tab and bring it with you along with any lotions or medications you have been using.  Your dermatologist can often help more effectively if you bring the actual creams / lotions to the appointment.
