For the past 28 years, when not a professor in the Department of Marriage & Family Therapy, Dr. Sellers has had a private practice. In her practice she provides psychotherapy, sex therapy and consultation for individuals, couples and families, as well as supervision and consultation for therapists and sex therapists.
Currently, due to her writing, training and speaking schedule, her own psychotherapy practice is limited to a small number of consultations as time permits. Tina however, is the Medical Director of the Northwest Institute on Intimacy which has a team of licensed advanced level therapists. Most of these therapists have trained under Dr. Sellers, and all are comprehensively trained in individual, couple, family, sex and spiritual intimacy therapy. Less than 5% of therapists in the US have training in all five of these areas. As Medical Director, Dr. Sellers also makes herself available to consult on complex cases that go through the institute.
