Basic dues are $30. Hardship cases may join for as little as $5. Donations (without membership) are welcome too. More details below.

Why should I join?

Our mission promoting awareness and accommodation can only be achieved if we have an interested member base. That gives us legitimacy, and gets people to notice us and to take us seriously. Join so that we can help you, and help many others who suffer from these disorders. Together we have a voice!

Members also receive these additional benefits:

Our near term goals:

Why now?

This is an exciting time for people with circadian sleep disorders, and for this organization. More and more doctors are becoming aware of these disorders, and are taking them more seriously.

We have started a patient registry and survey, which is expected to provide valuable information to researchers as well as study subjects (with their permission, of course).

NIH (U.S. National Institutes of Health) is updating its Sleep Disorders Research Plan with considerable mention of circadian sleep disorders, and we were able to get a CRD patient on the Sleep Disorders Research Advisory Board (SDRAB), the body advising NIH on the update.

We continue developing our plans and strategies, and populating the web site. We need members, so that we can claim to speak for the community, and be listened to and taken seriously.

About us

We are an all-volunteer organization. None of the board members or officers are being paid. We are using our funds for expenses, such as the cost of applying for tax exempt status, printing costs, web costs, etc. We are a 501(c)(3) charitable organization, entirely supported by member dues and contributions.

We see this as an international endeavor. While initially most of our activity will occur in the U.S., the information on our web site is available world-wide, and our brochures will be useful to English-speakers everywhere, and are being translated into other languages. The research we encourage will be useful world wide. In the future we hope to sponsor affiliated groups in other countries.

How much?

Annual dues, which run for the calendar year, are $30 (all amounts are USD). Dues are tax-deductible in the U.S. (see below). For dues received on or after Oct 1, membership is effective immediately but will run through the following year.

If you feel you cannot afford our dues, you may pay less. But a minimum of $5 is required. Please give as much as you can afford.

We would like to encourage people to join as Sustaining Members for $75. Joining at this higher dues level helps us progress more quickly toward our goals. Note that this is still a one-year membership.

And of course, any amount you wish to donate above the basic dues level is welcome as well.


You can pay through PayPal or by check. You don't need a PayPal account to pay through PayPal, but if you do use PayPal, you will need to enter credit card information, name, address, and email address. We never see the credit card information, you interact directly with PayPal at that point, and only PayPal gets that information. We can see some of the other information. PayPal is easier for you, because you don't have to remember to write a check, address an envelope, and add a stamp. We prefer it too. Of course you can send a check if you prefer.

But you need to submit the following form first. All membership information is confidential - see our Privacy Policy. All information on this form is voluntary, except the amount and your email address, and whether you are joining or renewing. And we'd appreciate your checking the box corresponding to your disorder (if any). This will only be used statistically, to count how many of our members have which disorders.

Clicking on Pay with PayPal takes you directly to the PayPal website, provided you have javascript enabled (most people do). If not, you will get another page with a PayPal button that you must click yourself. Once on the PayPal website you can enter your PayPal password and (if they don't already have it) your credit card or banking information. Note that Circadian Sleep Disorders Network never sees that password or credit card or banking information - that travels directly between you and the PayPal website.

Clicking on the Pay by Check button takes you to a page with instructions for sending your check.

Income tax deduction

We are a 501(c)(3) tax exempt charitable organization (United States Internal Revenue Service). Your membership dues and donations are tax-deductible in the United States.

Privacy policy

We take your privacy seriously. We understand that you may not want your membership in Circadian Sleep Disorders Network to be public information, and we take every precaution to keep your data private. We will never sell or give away our membership information. That promise is enshrined in our bylaws!

Our membership list is private, and only accessible by the few people with a need to know. Currently, that is the president, vice president, treasurer, and secretary, since they need to process your membership dues, email the election ballots, etc. The election ballots are processed by a third party (, so they do get your email address, but they promise not to use it other than for the conduct of the election. We use MailChimp to send the newsletters, so we don't trigger spam blockers, so they too receive the list of email addresses.

We are not requiring members to provide any more personal information than they are comfortable providing. However, if you do not give us a valid email address, we will not be able to contact you at all, so we do ask for that.

If you pay using PayPal, only PayPal gets your payment data (bank account or credit card). We never see this information. We can view the name and email address you provide to PayPal, and in some cases the street address as well, but we will not make use of this. You may also pay by check. We will not retain any bank data from the check.

We will retain your membership information for three years after your membership lapses, to allow us to send renewal reminders and perhaps some especially important news. After that, all information about you will be deleted.

Our Mission

Circadian Sleep Disorders Network is an independent nonprofit organization dedicated to improving the lives of people with chronic circadian rhythm disorders.

We aim to increase awareness within the medical community and among the general public, to provide emotional support and practical ideas for people living with these disorders, to inform patients and health care providers about treatment options, to encourage research into circadian rhythms, and to advocate for accommodations in education and employment for people with circadian rhythm sleep disorders.
