Cottonwood Tucson's Staff

A Team of Caring Experts

At Cottonwood Tucson we are grateful to have been able to gather, from across the country and around the world, a group of uniquely talented individuals who have hundreds of years of combined experience in the treatment of behavioral health disorders.  Please take some time to meet these highly trained and seasoned clinicians, many of whom are leaders in their fields.  A number of our medical and program staff currently hold faculty positions at area colleges and universities, including the University of Arizona School of Medicine.

Even as important as our professional qualifications, many of our addiction treatment professionals and clinical staff have felt the same pains and problems you or your loved one may now be experiencing.  Some of us have suffered from depression, alcoholism, drug addiction, co-dependency, trauma, and other issues.  For each of us, our greatest growth has come through facing our pain and learning the skills necessary to successfully overcome it.  Through confronting and understanding the problems in our lives through addiction services or co-occurring disorders treatment, we have become happy, confident people.  Our personal successes in recovery are a direct result of the ongoing effort each of us has put into developing the attitudes, beliefs and values that bring wholeness to our lives.  Our hard work in the recovery process has been rewarded with contentment, balance and joy, and we are eager to share the benefits of our hard-won insight with you.  Those of us who work at Cottonwood believe that nowhere in the world is there a better place to make the discovery of a happier, more productive you.

Doctor of Nursing Practice
Member of the Cottonwood Team since 2019

Dr. P. eventually relocated to Arizona, where he treated patients in an outpatient practice before realizing how much he truly loved the inpatient/residential level of care. His affinity for this care model comes from its ability to provide both the patient and the provider with an environment to closely monitor treatment on a weekly basis, as opposed to an outpatient model which is often plagued by enormous caseload ratios per provider, sometimes causing up to a three or four month wait to see a provider.

Outside of the work environment, Dr. P. is a father and husband, and enjoys comic books, comic book and horror conventions, movies, as well as collecting lots of 1/6 scale pop-culture action figures!

Michele is based in London, UK, and is a BACP registered psychotherapist and counsellor with a Master’s degree in Psychoanalytic Studies from the Tavistock and Portman. She worked for seven years at the Priory Hospital Roehampton and was the Addictions Treatment Manager until August 2017. Michele has considerable expertise in sourcing therapeutic solutions for a varied client base in the field of addictions and mental health for over a decade. She has a private practice in Bond Street, London, and is a couples and family therapy specialist. She believes that talking together as a family often delivers transformative changes to relationships in a short space of time. Previously, Michele travelled widely and worked in many different settings, including 14 years at the BBC in London to working as a psychotherapist in the prison service and then the private sector. This variety has made her a creative practitioner with an assortment of life skills that flavor her work. Michele is delighted to be working for Cottonwood Tucson to focus on London, the UK, and Europe to build relationships with clinicians to enable them to source good treatment options for their clients. Michele has found that Cottonwood delivers solid treatment with gravitas, truly treating the client as an individual in a beautiful, restful desert setting. Michele has found that her own recovery from addiction worked best when it flowed holistically – mind, body and spirit together – and this ethos is what she found in abundance in the program at Cottonwood.

In her spare time Michele enjoys the thriving art and theatre scene in London, watching films with her family, creative writing, yoga and exploring the outdoors – especially the Highlands of Scotland. Michele is an avid polo and football spectator and is very proud to be at the beck and call of her oversized German Shepherd dog.

Business Development Representative
Member of the Cottonwood Team since 2020

Maggie’s received her Master’s in Clinical Psychology from Antioch University. Through both personal and professional experiences, she found a passion for working with Family Systems. The framework through which she practices is focused on treating the dynamics of the system that contribute to the behaviors of the individual.

She has worked at all levels of care at multiple behavioral health treatment centers. She understands the complexity of treating the family as a whole. Her specialty in family systems lead her to working with other clinicians, psychiatrists, and facilities in the pursuit of psycho educating other professionals about the benefits of treatment. She is passionate about helping families and individuals heal.

Before joining the Cottonwood team, Maggie had referred clients to the program. After experiencing the breadth of their clinical work with both the family and the individual, she knew that Cottonwood fell perfectly in line with her personal clinical ideology.

When she is not pursuing her passion of helping families and individuals seek treatment, she can be found either in a yoga class or taking her two dogs on a hike in the Santa Monica Mountains.
