Memberships FAQs

  • Can I start using my MMA benefits right away?

    Yes! Regardless of how you join—online, in person, or over the phone— your MMA benefits are available to you as soon as you complete your purchase.

  • How long is a membership good for?

    Your membership is good for one year from the date of purchase.

  • Is my membership tax-deductible?

    The MMA is a 501(c)(3) nonprofit organization. The amount of membership dues that is deductible for federal income tax purposes is the amount paid less the fair market value (FMV) of benefits provided in return, whether used or not. Our memberships are fully deductible. We always recommend that you consult a tax advisor with questions.

  • Who may be named on my membership?

    For all MMA membership levels, except the ‘Individual’ membership, you may name up to two adults residing in the same household. If you have a nanny, babysitter, or caregiver who regularly brings the children of the member household to visit, we are happy to note his or her name on your record.

  • How do I renew my membership?

    Explore our membership options on this page, and click on the respective button for the membership level you’d like to purchase. Technically there isn’t a “renew” option on our new membership management platform, so the process is just like purchasing a new membership. 

  • How do I avoid creating duplicate accounts if my membership has lapsed and I’d like to buy a new one?

    In order to associate a membership purchase with your existing account in our system, please enter your name and email as you did when you purchased the membership. 


    Can't remember? Reach out to us, and we'll be happy to verify for you! info@mariamitchell.org 

  • How do I use my membership on your system?

    After you purchase a membership, you’ll need to activate it by entering your information on this link. Please register using one of the names and emails associated with your active membership. 


    Once you’ve entered your email address and a password, you should see your email address at the top right corner of the page. This is how you know you’re signed in. You’ll also get an email confirming registration.  


    Our system should keep you logged in on your browser. Do verify you’re logged in when you’re ready to register for programs and camp. If not, just click on “Sign In” in that same corner. This ensures you’ll receive the member discounts for programs, and will allow you to register for Discovery Camp, which is only open to Members.


    Tip: We encourage you to write down the email address and password you enter when activating!


  • Are memberships refundable?

    Memberships are non-refundable. Please contact us for extenuating circumstances, at info@mariamitchell.org.
