Section 302 of theSarbanes-Oxley Act of 2002

I, Edward J. Quilty, certify that:

1.    
          I have reviewed this annual report on Form 10-KSB of Derma Sciences, Inc. (the "Registrant");

2.    
          Based on my knowledge, this annual 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 such statements
          were made, not misleading with respect to the period covered by this annual
          report;

3.    
          Based on my knowledge, the financial statements, and other financial information
          included in this annual report, fairly present in all material respects the
          financial condition, results of operations and cash flows of the Registrant as
          of, and for, the periods presented in this annual report;

4.    
          The Registrants other certifying officer and I are responsible for
          establishing and maintaining disclosure controls and procedures (as defined in
          Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Registrant and have:

a)       
Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the Registrant, including its consolidated subsidiaries, is made
known to us by others within those entities, particularly during the period in which this report is being prepared;

b)       
Evaluated the effectiveness of the Registrants disclosure controls and procedures and presented in this annual report our
conclusions about the effectiveness of the disclosure controls and procedures, as of the end of the period covered by this
annual report based on such evaluation; and

c)       
Disclosed in this report any change in the Registrant's internal control over financial reporting (as defined in Exchange Act
Rules 13a-15(f) and 15d-15(f)) that occurred during the Registrant's most recent fiscal quarter (the Registrant's fourth fiscal
quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the
Registrant's internal control over financial reporting; and

5.    
          The Registrants other certifying officer and I have disclosed, based on
          our most recent evaluation, to the Registrants auditors and the audit
          committee of Registrants board of directors (or persons performing the
          equivalent functions):

a)       
          All significant deficiencies and material weaknesses in the design or operation
          of internal control over financial reporting which are reasonably likely to
          adversely affect the Registrants ability to record, process, summarize and
          report financial information; and

b)       
          Any fraud, whether or not material, that involves management or other employees
          who have a significant role in the Registrants internal control over financial reporting.
