        EXHIBIT 31

     I,Roger Tannery, certify that:                 1.     I have reviewed thisquarterlyreport on Form 10-Qof American        Development & Investment Fund, Inc.;                 2.     Based on my knowledge, this report does not contain any untrue        statement of a material fact or omit to state a material fact necessary        to make the statements made, in light of the circumstances under which

suchstatements were made, not misleading with respect to the period

covered by this report;                 3.     Based on my knowledge, the financial statements, and other        financial information included in this report, fairly present in all        material respects the financial condition, results of operations and cash        flows of the issuer as of, and for, the periods presented in this report;                 4.     I am responsible for establishing and maintaining disclosure        controls and procedures (as defined in Exchange Act Rules 13a-15(e) and        15d-15(e)) for the issuer and have:                 a) Designed such disclosure controls and procedures, or caused such        disclosure controls and procedures to be designed under my supervision,        to ensure that material information relating to the small business        issuer, including its consolidated subsidiaries, is made known to me by        others within those entities, particularly during the period in which this

report is being prepared;                 b) Designed such internal control over financial reporting, or caused        such internal control over financial reporting to be designed under our        supervision, to provide reasonable assurance regarding the reliability of        financial reporting and the preparation of financial statements for        external purposes in accordance with generally accepted accounting        principles;                 c) Evaluated the effectiveness of the small business issuer's disclosure        controls and procedures and presented in this report my conclusions about        the effectiveness of the disclosure controls and procedures, as of the        end of the period covered by this report based on such evaluation; and                 d) Disclosed in this report any change in the small business issuer        internal control over financial reporting that occurred during the small        business issuers most recent fiscal quarter (the small business issuers        fourth fiscal quarter in the case of an annual report) that has        materially affected, or is reasonably likely to materially affect, the        small business issuers internal control over financial reporting; and                 5.     I have disclosed, based on my most recent evaluation of internal        control over financial reporting, to the small business issuer's auditors        and the audit committee of the small business issuer's board of directors        (or persons performing the equivalent functions):                 a)     All significant deficiencies and material weaknesses in the

design oroperation of internal control over financial reporting which are

reasonablylikely to adversely affect the small business issuers ability        to record, process, summarize and report financial information; and                 b)     Any fraud, whether or not material, that involves management or

otheremployees who have a significant role in the small business issuer's

internal control over financial reporting.                 Date:August14, 2009
