8.15.22 || Cornerstones psychotherapist Ashley Moore begins ACT Training 

A. Moore-2.jpg

Acceptance and Commitment Therapy, or "ACT" (Say it, don't spell it!)  is an experiential approach to therapy that is informed by behavioral, cognitive, and relational frame theories.  It is, in short, a very different sort of therapy that makes a fairly surprising statement from the start-- we do not wish to change our emotions, and in fact we probably should not try.  So what should we do instead?  ACT has a lot of ideas about this.  We might "De-fuse" from our thoughts, accept our feelings, identify our values, and engage in committed action just to name a few.  Ashley is learning how to do just this (and, more importantly, how to walk residents through the process) by studying under Russ Harris, one of the foremost researchers and trainers in the ACT circle.  Thus far, Ashley has been soaking in all of the exciting experiential and metaphorical aspects of ACT, and has been using them regularly in sessions with residents.  She's finding that using this approach in therapy yields quick and meaningful results that are sustained over time.  Even more importantly, she is in awe of the way that residents enthusiastically engage, and demonstrate a sense of relief and validation, when this approach is utilized.  Ashley is thrilled to be training under Russ, and looks forward to learning as much as she can about this values-congruent (for her!) approach to therapy.

7.13.22 || Cornerstones welcomes our new Clinical Director: Dr. Eric Beaudoin

We are excited to announce the appointment of Dr. Eric Beaudoin to the role of Clinical Director at Cornerstones of Maine. Eric truly understands the mission, methodology, and spirit of Cornerstones. We are looking forward to his stewardship of our clinical program.

Eric took a position at Cornerstones immediately after completing his clinical internship while looking for post-doctoral training in advanced psychotherapeutic technique. He was one of our very first staff members and a part of the team when our doors opened in 2016.  Supervised and mentored by our founders, Dr. Altschule and Dr. Gelles, Eric received immersive training in individual, family, and group psychotherapy. He additionally continued didactic training in Transference Focused Psychotherapy, Mentalization Based Therapy, and other psychotherapeutic techniques. Over the last seven years, Eric’s clinical work has deepened and he has become an exceptional therapist with a personalized therapeutic style. He has proved to be a leader and mentor to the rest of the clinical team.

Born in Maine, Eric had the peaceful childhood life of a Mainer, but like so many, he yearned to see the world beyond the woods. He stayed in Maine for his bachelors at the University of New England, but in 2008 he traveled to the other side of the United States to attend a doctoral psychology program at the Chicago School of Professional Psychology in Los Angeles. After graduating with his doctorate he returned to Maine. While providing a grand adventure, the big city had given him a new appreciation for a simpler life. In Maine, Eric sought out post-doctoral experiences but was dissatisfied with the available options. He turned to cold-calling the friendliest faces he could find on Psychology Today’s website. After ten or so calls with no responses, he ended up on the phone with Dr. Altschule who casually chirped, “Well, I’m starting a program. Let’s have lunch.” Ten minutes into lunch he was sold on the clinical vision and expertise of Dr. Altschule. He was at Cornerstones on the day we opened our doors and the ensuing first years of the program, which were an exercise in persistence for the Cornerstones team as they patiently worked to turn Cornerstones into the well-regarded program it is today.

Eric is a strong believer in the deeply-relational milieu-based therapeutic work of Cornerstones. He also subscribes to an integrated theoretical approach to clinical work. Eric reports that this approach is based in psychodynamic conceptualization, such as transference focused psychotherapy, with adaptations given the milieu model and the necessity of a short-term scope of intervention. Eric ascribes much of his clinical success and the approach he has developed to the Cornerstones residents and the many lessons he has learned from them over the years. As he notes, “The residents remind me of how I struggled in my formative years. What could easily be perceived as petulance, laziness, or entitlement is more intimately understood by me to be fear of rejection, mourning of childhood’s end, and the shame of failure.” He also makes it clear that Dr. Altschule’s supervision was integral to helping him become the clinician he is today, “Josh taught me how to be both a connected and engaged real person and a clinical therapist at the same time, as well as how to work clinically within a real relationship.” Dr. Altschule is moving out of the role of Clinical Director into the role of Executive Director, which he will share with his co-founder, Dr. Gelles.

7.13.22 || Cornerstones staff to present at the National Association of Social Workers (NASW)
Annual Conference in Maine this October

Cornerstones is proud that two of our staff, Lacee DeLorey (pictured left) and Gwen Tuttle (pictured right), will be presenting at the National Association of Social Workers (NASW) Annual Conference taking place in October

of this year in Maine. The presentation is entitled,

“Frisky Business: The Importance of Comprehensive Sex Positive Education for Emerging Adults”. 

Lacee and Gwen have previously presented this workshop at the NATSAP Northeast conference in 2021 to resounding success. The workshop is based on Lacee’s sex positive education curriculum that she has provided to residents at Cornerstones of Maine for the last 4 years. Lacee developed her curriculum based on her many years of experience teaching sex education to adults and through courses she participated in through Planned Parenthood’s Sexual Education Cornerstones Seminar (SECS). Gwen Tuttle has collaborated with Lacee on her sex positive education curriculum and joined her in the development and presentation of this workshop. Gwen brings her interest in the impact of sex positive education in the processing and resolution of sexual trauma. 

Lacee and Gwen’s Sex Positive Education model seeks to do more than just provide traditional sex education to residents. It is intended to include the therapeutic benefits of reduction of shame and anxiety as well as the promotion of self-care and safety, strengthen self-acceptance, and increase awareness of the experience of others.  Incorporation of Sex Positive Education into academic and therapeutic programs supports all individuals, though it is especially crucial for residents  who identify as LGBTQ+ as they are a demographic that is typically neglected in this arena. This curriculum is positioned to positively impact clinical work in the areas of trauma, anxiety, and depression. The information covered in Sex Positive Education supports healthy relationships and provides important information to young people about consent and reducing sexual violence. They discuss concepts including enthusiastic consent, forms of protection, and basic anatomy. 


Lacee and Gwen are excited to share this important material with the treatment providers of Maine at the National Association of Social Work (NASW). Their hope is to inspire other providers to incorporate sex positive education into their programs and practice.    

Lacee DeLorey is the Residential Coordinator for Cornerstones of Maine. Lacee has been teaching Sex Positive Education for the past 7 years and is a strong advocate for the LGBTQ+ community. She is passionate about equal representation and distribution of rights among individuals who are often underrepresented.    

Gwendolyne Tuttle is the Clinical Coordinator for Cornerstones of Maine. She has been providing psychotherapy to young adults since 2015 with an emphasis on trauma-informed care. She has a strong interest in Sex Positive Education and how it intersects with treatment for sexual trauma. Gwendolyne is a certified Mentalization Based Therapy Practitioner and is currently in residency in the Doctor of Social Work program at the University of Pennsylvania.

5.1.22 || Cornerstones psychotherapists Kerry Bennett and Ashley Moore begin TFP Training 

A. Moore-2.jpg

Two members of our Clinical team, Kerry Bennett and Ashley Moore, are participating in a Transference-Focused Psychotherapy (TFP) supervision group, which is facilitated by Dr. Diana Diamond, a fixture of the psychodynamic community. Within this group, participants will engage in building a skillset of psychodynamic conceptualizations, interpretations, and interventions, while developing the technical language for communicating complex psychodynamic formulations. The supervision group also provides a platform to engage in countertransference self-reflection as a tool for informing clinical treatment.
