Information for clients

The following information for ECHO Lab clients provides details on our policies and procedures for using the Lab.

Participant list (required for security)

At least 48 hours in advance of the session, you must provide HCC with a list of all participants’ names. After the session, HCC will collect the list from the building’s security staff and confidentially retain the roster of names.

Client check-in

You are required to arrive at the ECHO Lab at least 30 minutes prior to the first session. Check-in processes vary depending on whether the session begins before or after normal business hours.

Monday through Friday 9:00 a.m. to 5:30 p.m.: You must check in with the building’s security staff in the lobby of 375 Longwood Avenue, then take an elevator to the 6th floor. You can use the house phone to call your HCC contact and gain access to the floor. Phone numbers are posted on the door.

Evenings or weekends: Because of the building’s security policies, you must call HCC (a number will be provided 24 to 48 hours in advance) when you arrive at the entrance to 375 Longwood Avenue. HCC will provide access to the building.

Participant check-in

Participants must check in with building security and then call your cell phone to be escorted to the Lab. During evening or weekend sessions, your HCC contact will accompany you to the lobby.
