Default Help with Complex SQL Select Statement

Hi to everyone here - This is my first post/question!

I have a problem in which I need to construct (what appears to be) a complex Select Statement. For brevity I list the data construct and the problem I need to solve.

My Data Strucutre:

JobId as Integer
ClientID as Integer
ConsultantID as Integer
ReviewConsultantID as Integer (***This call to lookup table is the problem)

ClientID as Integer
ClientName as String

ConsultantID as Integer
ConsultantName as String

My problem is that both the ConsultantID and ReviewConsultantID fields in the JobSheet_Master table need to lookup the Consultant_Master table to get the ConsultantName and ReviewConsultantName (which are different but both identified by the field ConsultantID in the Consultant_Master table. I have devised a temporary work around whereby I get the data I need from the select table and then do a separate datalookup to get the ReviewConsultant. I know this is inefficeint but cannot see how to construct a Select Statement that will achieve the results. Whilst I have only shown one example in this table, I actually have three instances of this that I need to solve, hence my query to this forum (which I hope is the right one!!)

The (abbreviated) SQL code I currently use looks like this:

SELECT JobSheet_Master.JobID, _
JobSheet_Master.ClientID, _
Client_Master.ClientName As ClientName _
JobSheet_Master.ConsultantID,  _
Consultant_Master.ConsultantName As ConsultantName _
JobSheet_Master.ReviewConsultantID _
FROM (JobSheet_Master INNER JOIN ConsultantID ON _(JobSheet_Master.ConsultantID=Consultant_Master.ConsultantID)) _
INNER JOIN ClientID ON (JobSheet_Master.ClientID=Client_Master.ClientID) _
ORDER BY JobSheet_Master.JobID "
Loading the results into a structure, I then do a separate SQL SELECT to get the Review Consultant Name.

Any help with constructing a SELECT clause that could get me both the ConsultantName and ReviewConsultantName from the Consultant_Master table would be very much appreciated.

Try this:

SELECT JobSheet_Master.JobID, Client_Master.ClientName, Consultant_Master.ConsultantName, (SELECT ConsultantName FROM Consultant_Master WHERE JobSheet_Master.ReviewConsultantID = Consultant_Master.ConsultantID AND JobSheet_Master.JobID = Client_Master.ClientID ) AS [Review Consultant]
Consultant_Master ON JobSheet_Master.ConsultantID = Consultant_Master.ConsultantID INNER JOIN
Client_Master ON JobSheet_Master.ClientID = Client_Master.ClientID
