Try this:

SQL

(SELECT DISTINCT A.AppointmentId
			   , U.UserId
			   , U.FirstName
			   , U.UserEmail
			   , (DATEDIFF(DAY, U.DOB, GetDate()) / 365.25) AS DOB
			   , C.CompanyName
			   , A.TimeStart
			   , A.Reason
			   , A.Status
			   , A.PatientFirstName AS FName
			   , A.PatientLastName AS LName
			   , A.PatientGender
			   , (DATEDIFF(DAY, A.PatientDOB, GetDate()) / 365.25) AS PatientDOB
 FROM
	 Appointment A, Users U, Company C
 WHERE
	 A.UserId = U.UserId
	 AND A.CompanyId = @CompanyId
	 AND A.ProviderId = @ProviderId
	 AND A.Date = @Date
	 AND C.Id = A.CompanyId)
UNION
(SELECT DISTINCT A.AppointmentId
			   , E.EmployeeId
			   , E.Name
			   , E.Email
			   , (datediff(DAY, E.DOB, GetDate()) / 365.25) AS DOB
			   , C.CompanyName
			   , A.TimeStart
			   , A.Reason
			   , A.Status
			   , A.PatientFirstName AS FName
			   , A.PatientLastName AS LName
			   , A.PatientGender
			   , (DATEDIFF(DAY, A.PatientDOB, GetDate()) / 365.25) AS PatientDOB
 FROM
	 Appointment A, Employee E, Company C
 WHERE
	 A.UserId = E.EmployeeId
