Membership Banner


No other organization represents the geotechnical consulting profession better than CalGeo. We offer membership options to meet the diverse needs of those serving the industry. Membership dues are tax-deductible as an ordinary and necessary business expense.

CalGeo works diligently on behalf of our members to raise the status of geotechnical engineers and geoprofessionals in the eyes of the public and other professionals. CalGeo offers continuous networking opportunities, highly educational events, and cost-saving services that have the cumulative effect of producing stronger, more profitable members in 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. We offer member pricing to all members throughout the year.

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).
