Like all Shift Psychologists, Dr Lindsay is trained in the Shift Protocol, which is the highly effective blending of two well-researched approaches: Cognitive Behavioural Therapy (CBT) and Bilateral Stimulation. She also has experience in mindfulness, solution-focused, and Acceptance and Commitment Therapy techniques. She completed her PhD at the University of Saskatchewan where she was captivated by her research on the treatment of psychopathic sexual offenders.


What is your name/nicknames?

My closest friends all call me “Sewall” or “Linz” – it’s jarring to hear “Lindsay” when I am with them! My family calls me “Sheso” which began over a decade ago when my brother mailed me a package to “Lindsay Sewall c/o ‘Stu Pidsister’ “and it evolved from there.

What do you do at Shift?

I am a registered psychologist at Shift Mount Royal in YYC. I am the clinic manager and head of clinical training for our new Shifters. I am currently helping to develop an online training portal so we can have the best training for our psychs. I am also co-authoring a book on our Shift approach so we can try to share our model with as many people as we can (one of our values is to increase accessibility)!

What are your academic credentials?

I have a doctorate degree in clinical psychology from the University of Saskatchewan (fun fact – my dissertation was on psychopaths). I am also constantly listening to podcasts and reading books on all things related to upping your life game.

Do you have any pets?

I freaking wish I had a snarfly little bulldog, but that will be a year or two down the road. For now, I get my dog fix in my parent’s odd looking rescue dog, Bosley, who really has no interest in me or anything that anyone wants from him, which I find endlessly amusing.

Who or what inspires you and why?

When people put themselves out there to do things they’re afraid of or are outside of their comfort zone in an effort to grow. Oh, and my spirit animal Brene Brown’s research or shame and vulnerability.

Specialty Populations/Issues:

Anxiety and mood disorders, stress, trauma, relationship issues and Executive Coaching


What is your favourite food?

Being a child of the ‘80s, I cannot deny my love for KD and Ichiban. But for real food, I’d say margarita pizza, pico de gallo, and anything with roasted tomatoes. I could eat those three for every meal. But I also love to cook and try new things so I definitely like some variety!

What is a skill you are working on currently?

As a recovering perfectionist, I am on a mission to develop hobbies after years of giving up if I wasn’t immediately good at something (i.e., all things). So, I am working on moving from a fixed mindset (I can’t do it) to a growth mindset (I can do it if I put in the time). This means I am really working on trying to do things I would have previously avoided.

What do you do in your spare time?

Based on the previous question, I now spend my time learning guitar (love country music!), trying to paint, hand lettering (a goal from 2017), and making homemade cards (my fave gift to give and receive). I also love spending time with my big group of awesome friends and family, hitting up the farmer’s market with my husband, and being near water as much as possible.

What is your dream car?

I am just not a car guy. I will drive my very practical 2005 Honda CRV until the wheels fall off! The only other car that I think would be so dope to own is an El Camino…the mullet of cars!

What is your go-to for a good laugh?

I laugh super easily, but it helps that I am surrounded by a boatload of funny people in my life. I actually laugh often with my clients! Who says therapy has to be all serious business?! Outside of that, nothing makes me laugh harder than when someone gets a really clever but unexpected burn on my buddies or me. Also, watching my parent’s dog be a rude jerk always gets me!

Dr. Lindsay thoroughly enjoys helping individuals overcome anxiety and mood disorders, stress, trauma, and relationship issues to increase their overall functioning. Lindsay brings enthusiasm, warmth, openness, and a dash of humour to establish a nonjudgmental therapeutic relationship, where clients are able to explore where they may be feeling stuck, develop new adaptive strategies, and create a more fulfilling life. In the past, she has taken a collaborative approach when working with individuals, couples, groups, and students of all ages across hospital, rural clinics, and forensic mental health settings. She feels strongly about empowering clients whether through therapy or recommendations offered through comprehensive assessments. When she is not immersed in collaborating with clients to create true satisfaction with their lives, you could find her talking about, thinking about, cooking up, or devouring delicious food, or bringing out her inner HGTV star by attempting to tackle home renovation projects. She also really loves laughing too loud, singing every word to country music, and being by water as often as possible.

Nothing found.

If you’re like me, you hear about the latest self-improvement book, maybe through a friend, on a table at Chapters, or even on the cover of O magazine while you’re cashing out at the grocery store, and you think “hey! I should pick that up!” You buy the book with every intention of reading it…but then you get busy, you work all day, commute home in rush hour, make dinner, get the house in order, and by the time you have a few minutes to read the only thing you have energy for is crappy reality TV or brain candy books (I’m looking at you, Amy Schumer’s memoir). The self-improvement book sits on your shelf gathering dust.

Well, I have discovered a fantastic solution. Audiobooks! These are great for finally getting through those books while on your commute or for listening to while you’re going for a walk or using the treadmill! My go-to place for audiobooks is They have a ton of really great life enhancing books available (and some of those brain candy ones too). This is a great option for getting around to finally getting to those books and making your life a little more awesome!
