In the clinic

We are accepting new patients 18 years of age and older.

Please call the office to schedule an appointment.

We are screening ALL patients for COVID19 symptoms at the time of appointment confirmation. 

We require everyone in the office to properly wear a face mask (covering nose and mouth) at all times.

If you would like to be seen in-person, we are seeing asymptomatic patients in the office. Do not enter the office if you have symptoms.  If you are ill, please let us know at the time you schedule your appointment. We have a separate protocol to see you if you are sick.

We are also conducting televisits. Please sign and return these forms: About Telemedicine. Consent for telemedicine.

Update 4/25/2022:

COVID vaccines are recommended for individuals >5 years old to prevent severe disease and death. Keep in mind that vaccination has decreased efficacy against variants compared with the original strain, and the current circulating variants result in a much higher viral load than the original strain.  Therefore, you can still contract COVID after vaccination.  Most vaccinated COVID cases appear to be mild cases, however, rarely, you may still develop severe disease and should still seek care with your doctor.  You are also contagious and may spread this to someone who can have severe or fatal consequences from COVID.  This virus does not care about your species, age, gender, beliefs, health, prior infection or prior vaccination status. With each infection, this virus is mutating and outpacing the gains we have made in our diagnostics, treatments, and vaccination efforts.  Therefore, please continue to mask (n95/kn95 or equivalent) and distance.  It is critical that everyone does his/her part at this time. 

COVID vaccine appointments

  • You can register with LAC DPH at a location of your choice. You can also register with your local pharmacy

  • If you are in Pasadena City, you may call PPHD at 626-744-7311 to register for an appointment. 

We have 3 vaccines that are being administered in the US. These are strongly recommended to protect against severe or fatal COVID outcomes.


  • Boosters are recommended for everyone18+yo.

    • There is evidence of persistent adequate neutralizing antibody titers at 6 months after Moderna.  Pfizer also submitted a similar update.

    • There is evidence of decreased protective antibody production in patients with blood cancers such as CLL or multiple myeloma.

    • This study revealed some benefits of a 2nd booster. 

  • Mixing vaccines is ok.

  • The distribution of vaccines to those who are yet unvaccinated is an important priority as this pandemic's future is a worldwide concern. A concerted effort across the globe with vaccines, masking, distancing is critical to stemming this virus's mutations and continued survival.

Things everyone should do

  • Wear a mask. This is the #1 most effective way to prevent transmission. 

    • n95 grade or better is recommended as COVID spreads by airborne transmission.

    • Do not touch the outside of your mask. It is considered contaminated. There are many videos on proper mask wearing.

    • With mask wearing, most people forget to hydrate. Please remember to drink adequate amounts of fluids

  • Social distance. Stand >6 feet from other people (when outdoors).

  • Stay in well-ventilated environments. Invest in a HEPA air filter, which can help filter viral (and bacterial) particles.

  • Clean your hands and environment.

    • Wash your hands with soap and water for at least 20 seconds. Hand sanitizer is ok to use if your hands are not soiled. Hand sanitizer should have >60% alcohol content to be effective.

    • Avoid touching your eyes, nose or mouth with unclean hands.

    • Disinfect frequently touched surfaces (ie. doorknobs, computer keyboard, phone).

    • Put the lid on the toilet before you flush to prevent aerosolization of toilet bowl contents.

  • Avoid close contact with people who are sick. If you came into contact with someone who tested positive or who is suspicious for COVID19, please isolate yourself and notify Dr. Poon.  

  • Get plenty of rest.

  • Do not do anything risky. This is the time to focus on taking care of yourself. Please do not ignore any health concerns. Please call the office as you would normally for any problems that may arise.

  • Get a pulse oximeter for your home. Every household should have one.

  • Please follow the trends of COVID-19 going on at the National level, state level, county level, and city level.
