 The office is in The Marshall Street Professional Building, 2455 NW Marshall Street, Suite 12. Portland OR 97210. Our lovely one story brick building is located between NW 24th and NW 25th (closer to 25th). Access to our office is through a large central courtyard garden.

If you are walking or biking you may enter the courtyard from either Marshall or Northrup Street. From Marshall Street turn towards the right upon entering the garden; you will see Suite 12 straight ahead. If you approach from Northrup Street, after entering the garden gate walk towards the left, heading to Marshall Street, proceed up the stairs and ramp and you will see Suite 12 on your left. 

bike rack is in the parking lot. 

The Streetcar and Bus lines (15 and 77) are a few blocks away.

Parking: There is plenty of off-street and street parking. You may access a parking lot from either Marshall or Northrup St. The Marshall St. lot has easier access to the office and also wheelchair access. When entering from the Marshall St. lot, after passing through the gate, turn left up the ramp. Suite 12 will be on your left.

Finding a street parking spot in NW Portland is becoming more difficult. The city has instituted changes requiring folks to pay for stickers (if they live in the neighborhood) and they monitor how much time a car is parked on the street if they don’t have a sticker. Some people have parked in our lot taking up spaces meant for people coming to see us. For this reason, the building management now has a towing company monitoring the lot. Any car parked in either lot longer than 2.5 hours will be towed. Please do not leave your car in the lot while you go for lunch or shopping on 23rd Avenue – your car may not be there when you return! If for some reason, you need to be at the office longer than 2.5 hours, we will issue you a day pass.


Our office has a calming contemplative inner courtyard garden  which you will walk through to enter.

We urge you to linger.

Spend some time strolling and relaxing in the garden before or after your visit. You may enter the courtyard garden from either Marshall or Northrup Streets or the Marshall St. parking lot.
