reviewed this annual report on Form 10-K of Floridian Financial Group, Inc.;

2. Based on my

(as defined in Exchange Act rules 13a-15(f) and 15d-15(f)) for the registrant
and have:

(a)
Designed such disclosure controls and procedures, or caused such disclosure

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)

internal control over financial reporting to be designed under our supervision,

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):

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

who have a significant role in the registrants internal control over financial
reporting
