I, Edward J. Quilty, certify that:

1.    
          I have reviewed this quarterly report on Form 10-QSB of Derma Sciences, Inc.
          (the Registrant);

2.    
          Based on my knowledge, this quarterly 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 quarterly
          report;

3.    
          Based on my knowledge, the financial statements, and other financial information
          included in this quarterly 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 quarterly 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 report our
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

| | (c) Disclosed in this report any change in the Registrants internal control over financial reporting (as defined in Exchange
Act Rules 13(a)-15(f) and 15d-15(f)) that occurred during the Registrants most recent fiscal quarter 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 of internal control over financial reporting, to the
          Registrants auditors and the audit committee of the 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.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|                          |                                                                                                                |
