CalGeo offers networking opportunities, educational events, student development, engagement with agencies, daily communication, an Annual Conference, and a CEO Summit that all support the advancement of its members and the geoprofessional industries.

When you join as a company through the appropriate link below, any members you enter as part of your company will receive a copy of all mailings and emails generated by CalGeo (notifications of meetings, conferences, workshops, training classes, the newsletter, any special bulletins, etc.). You may also designate additional branch offices to receive this information at no charge. Exclusive member pricing is provided for all offerings.

PLEASE NOTE, if you have a coworker who says they are already a member of CalGeo, this means one of two things:

  1. Your firm is a member, and you can have a profile added and enjoy all member benefits at no additional cost - email us at [email protected].
  2. If your coworker is an Individual Member, you may consider having the firm join as a firm. Individual member dues from that year will be pro-rated and applied to the firm membership, and you can have many more coworkers from your firm participate for one reasonable price (see below).
