Phyllis works with stress, Anxiety, anger management and depression

Phyllis lists 8 specialisms and 3 further focus areas. Specialisms are the subjects Phyllis chose to list first, which is the closest a listing gets to “this is my actual practice”.

02 · In Phyllis's own words

What Phyllis says about the work

Reproduced in full and unedited - not summarised, not tightened, not rewritten in a house voice.

I have had the privilege of working in many areas of the mental health field over the last 15 years, and this has shown me that people have the ability to heal given the right tools.

I have experience with anxiety, depression, anger management and PTSD. I have training in Cognitive Behavioral Therapy and Dialectical Behavior Therapy. I am empathetic and genuine in my approach, as I believe it’s important to feel both accepted and heard by your therapist. I employ a straightforward style but like to incorporate humor as well.

Change is always possible, but it is difficult.

03 · How Phyllis works

The 3 approaches Phyllis lists, in plain English

These are the clinical methods Phyllis lists. The descriptions are Maker Therapy's, not Phyllis's - a general explanation of what each method is, so the list means something before you have spoken to anybody. They are not a claim about how Phyllis runs a session.

Cognitive Behavioural TherapyCBT

Structured, present-focused work on the loop between what you think, how you feel and what you then do. Usually means noticing a thought pattern in the room, testing it against evidence, and practising something different between sessions. Among the most heavily researched talking therapies for depression and anxiety.

Dialectical Behaviour TherapyDBT

A structured skills-led adaptation of CBT built around holding two things at once: accepting yourself as you are and working to change. Teaches concrete skills for distress tolerance, emotion regulation and relationships. Developed for people whose feelings arrive at overwhelming intensity, and strongest-evidenced there.

Mindfulness-Based TherapyMBCT

Trains attention on what is happening right now - body, breath, the thought as it arrives - so distress can be observed rather than automatically acted on. Strongest evidence is in preventing depression from recurring, and it is usually taught as a practice you keep doing outside the session.

04 · What happens next

From this page to a first session

Phyllis practises through BetterHelp, so the route in is BetterHelp's. This is that sequence, written by Maker Therapy from the platform's published process - not a description of Phyllis's own practice, and not a promise about how quickly anything happens.

1. A questionnaire, not a booking form

   BetterHelp opens with a set of questions about what you are dealing with, what you want from therapy, and any preferences on the therapist. You are not booking Phyllis at this point.

2. Naming Phyllis specifically

   BetterHelp matches algorithmically by default, so asking for Phyllis is a step you have to take. There is a field for requesting a specific therapist during sign-up, and you can switch afterwards from your account. Starting from a link on this page does not by itself assign you to Phyllis.

3. If the caseload is full

   You will be offered somebody else rather than put on a waitlist. Worth knowing, because it is easy to assume a match is the person you asked for.

4. The first conversation

   A first session is typically history and orientation: what brought you, what has been tried, what you want to be different. It is also where the questions in the next section belong.

5. If the fit is wrong

   Changing therapist on BetterHelp does not need a reason. A first session that does not click is common and is not a verdict on therapy. That option existing is the main practical difference between a platform and a private practice.

05 · Before you commit

2 questions worth asking Phyllis

Built from what Phyllis actually lists, so they are answerable and specific rather than generic. Maker Therapy's, not Phyllis's - Phyllis has not seen them and is under no obligation to answer any of them.

• “How do you decide when someone is ready to work on a traumatic memory itself?”

  Pacing is the biggest safety question in trauma work. A clear, unhurried answer here matters more than any credential.

• “How do you handle the gap between sessions if something comes up?”

  On BetterHelp this varies a great deal by therapist. Better to know the rhythm now than to discover it on a bad week.

07 · Provenance

Where every line on this page came from

Phyllis's name, credential, state, subjects, approaches and biography are read from BetterHelp's therapist roster, which Maker Therapy re-reads once a day; this page reflects the reading taken on 9 Oct 2026. The licence number and NPI are cross-checked against public registers.

The plain-English method descriptions, the first-session walkthrough and the questions are written by Maker Therapy and labelled as such wherever they appear.

Maker Therapy is not BetterHelp, does not take bookings, and has not met Phyllis. There are no reviews or ratings on this page because we have no way to verify one. If you start therapy through a link here, we may be paid a commission - it does not change your price and it does not affect who appears here or in what order.
