Diamond's typical process when working with patients is to first establish a therapeutic rapport by asking open-ended questions. Diamond asks questions such as, "Have you been in therapy before, including as a  child or teen (if the patient is over 18)"? This helps Diamond starting point to build a trusting & individualized relationship with the patient. Diamond's next question would be, "Why did you first enter therapy & we're you diagnosed with any mental health disorders"? Diamond continues to go on and ask if the client is or has been on psychotropic medications and what brings them back to therapy. Diamond gathers all of this information during the first two session and then ask the patient if any skills were built during their therapy journey & if they still utilize the skills. Finally, Diamond would administer the ACE Questionnaire to assess for childhood trauma, if the patient is over 18 years of age.
