Our Milwaukee Therapists

Meet our female 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.

Welcome to our site!

I will work to assist you in identifying your own strengths and how to nurture and harness these strengths to meet your unique goals for therapy and life. You have a wealth of knowledge about what works and what does not work- I’m here to help organize this information in a useful way and help you fill in the blanks or help problem solve areas where you might be stuck. I’m ready when you are.
