Our Milwaukee Therapists

Meet our psychiatrists, psychologists, TMS experts, and therapists.

While all of our Milwaukee therapists share a common goal, providing premium care in a safe environment, we know that therapy is not a one size fits all process. We have multiple therapists here at New Frontiers, with a variety of styles and specialties. This allows us to ensure that our patients get specialized care in a comfortable setting, whether that is in-person at our Milwaukee office or via Telehealth appointments.

Dr. Joanna Love

Psychologist, PhD

I understand that assessment is an ongoing and collaborative process. I share the knowledge I have gained through my education and experience, so clients understand what informs my practice. I am very transparent with my perspectives, so clients shouldn’t have to wonder what I am thinking. I am far more interested in understanding the unique individual rather than focusing primarily on the specific diagnosis or problem.
