Where is your story taking you?

Olivia O’Brien, MSc, CPC | Sister Siren

Certified Professional Coach & Consultant based in Southern California.

  • Positive Psychology Master's Graduate.

    Olivia recently completed her Master’s of Science (MSc) degree in Applied Positive Psychology (MAPP) at the University of East London. She aims to weave scientifically-backed methods and evidence-based approaches into her work with her clients and her community. She intends to continue learning and growing in her field as a leading-edge researcher in the staunchly ignored field of Positive Dating & Singlehood.

  • Certified Professional Coach.

    Olivia was certified as a professional coach (CPC) in January 2021 by Coach Training World (CTW), where she received her training in the Fall of 2020. As an institution recognized by the International Coaching Federation (ICF), CTW specializes in “Whole Person” Coaching. As a Master’s of Science graduate, Olivia is now integrating more coaching approaches and evidence-based methodologies to her work than ever before.

  • SPARK Resilience Program Facilitator

    In 2024, Olivia was trained and certified to facilitate the SPARK Resilience program, and even expanded the course for online dating users within her Master’s dissertation. “Studies conducted to prove the efficacy of the [SPARK program] for resilience have found positive results across several PERMA well-being variables (e.g. lower negative emotion and higher positive emotion, higher self-esteem and engagement, and a greater sense of meaning), as well as additional benefits such as lower perceived stress and depressive symptoms, and higher degrees of self-efficacy and satisfaction with life,“ (O’Brien, 2024).

  • Proven client success.

    “Simply put, coaching with Olivia has been an incredible experience…. Her approach has allowed me to bring [my] goals into actionable steps and move closer to where I want to be. I can’t recommend working with her enough!”
    — Meg, 24, Project Manager, Graphic Designer (Seattle, WA)

  • Dating & relationship expert.

    150+ page Master’s dissertation on online dating, well-being, and resilience. 100’s of hours spent in the psychological research of Positive Relationships and personal / communal wellbeing. 1,000’s of videos watched, podcasts listened to, and stacks of books read on dating, attraction, attachment, energies, spirituality, mindfulness, and more. Years worth of dates under her belt (with plenty of dating app research, trial, and error). All this wisdom and experience has led Olivia to help millions of people as they navigate dating, relationships, and self development in the 21st century.

  • (Positive) Influencer.

    With a growing social presence on TikTok (75K and counting) and Instagram (with YouTube coming soon), Olivia’s growth on social media is a testament to her passion for helping people become hopeful romantics. She continues to create content that encourages and inspires, and in so doing, builds a community of like-minded lovers and change-makers across the globe.

  • "Modern Dating Master Class" creator.

    Olivia’s life’s work as a certified professional coach and dating expert packaged into one ultimate course. The Modern Dating Master Class aims to help those struggling in dating and relationships break through their limiting beliefs, harness a positive mindset, integrate their most attractive energy, and meet (and keep!) the match they so often dream about.

Out of the ashes… rise.

Now back from London (her childhood dream), where she obtained her master’s degree in Applied Positive Psychology (with a focus on Positive Relationships and Singlehood), Olivia is living out her passion and purpose in real time, harnessing new knowledge, wisdom, strength, and resilience that she hopes to pass along to those open and ready for positive change… including you!

Olivia first started on her journey of growth and self-actualization nearly ten years ago. In the midst of a panic attack on her dorm room floor, she decided that it was time to go to therapy. The world as she had known it was burning before her eyes, and she along with it.

Thus began years of deconstructing a narrative she had held so dear in her childhood, and reconstructing a new world view that better suited both her reality and the dreams that lay before her… but seemed so out of reach.

Abundance is your birthright.

After many years of “doing the work” (i.e. working through and learning about mindfulness, attachment theory, feminine & masculine energy, psychology, relationships, spiritual practices, and more), Olivia began training in an ICF-certified coaching school to gain the title of Certified Professional Coach (CPC) in 2021. She simultaneously built a following on social media, sharing her love of learning, laughter, well-being, spirituality, and travel.


Thus was born Sister Siren Coaching, LLC. Founded in 2021, SSC is dedicated to helping people tap into their inner wisdom, combat their limiting beliefs, unlock their potential, and feel safely supported as they emerge into their best possible self.

This dedication was expanded in 2023 as Olivia began her Master’s of Science degree in London, UK, studying applied positive psychology (MAPP) and focusing her research on positive dating, relationships, and singleness. Having recently graduated from the program in November 2024, Olivia is now fully equipped with science-backed theories, tools, models, methods, and interventions to help her clients thrive, no matter their circumstances.

So if you’ve been struggling and desire well-being, encouragement, confidence, and a life filled with meaningful, abundant joy, SSC might just be what you’ve been searching for. With professional guidance, psychological methodologies, evidence-based coaching approaches, and lots of genuine compassion, you can fast-track yourself into the strong, resilient, confident, capable hopeful romantic you know you can be.

Are you ready to rise?

“Olivia creates a safe container to explore my shortcomings; She helped me find my own inner power. I learned so much working with her, and I am truly enjoying this experience called life.”

Colleen, 42, 1:1 Coaching Client

  • “Olivia is a dating guru! Not only did she help me manage my own relationship anxiety, but she gave me actionable advice on how to prevent it in the future. I have gone from self-sabotaging all the time, to tapping into my feminine energy and attracting more of what makes me happy!”

    Sarah S., 1:1 Coaching Client

  • “I watched a Tik Tok from Olivia and immediately knew I needed to work with her. I think her course is amazing for beginners but also an incredible refresher…. Without her support I would be in another pretty crappy situation. Instead, I am learning to honor where I’m at & to continue striving to find the love I know I deserve.”

    Kelby M., Modern Dating Master Class Member

  • "I am very honored to say that she is absolutely the best coach I could've ever imagined working through my divorce with. I knew I needed to do the work to heal and attract in better partners, and Olivia helped me do it. She is very therapeutic, empathetic, and wise. She helped me untie the knots of my past and enter into my future full of freedom. Invest in yourself! It is so worth it!"

    Sarah A., 45, Fledgling Package Client

  • “Working with Olivia has been life-changing. She is a fabulous and empathetic coach with incredible insights. In the past, I have been a skeptic about the power of positive thinking, but Olivia has made me a convert."

    Sarah Joy, Modern Dating Master Class Member

  • “For the first time, I saw myself as confident and poised; someone who knows how to make decisions.As a coach, she guided me while I stepped into this new version of myself; she helped me narrow down a clear plan of action to continually embody who I really am.”

    Chad S., 1:1 Coaching Client

My top 10 values.

 

1. Love.

To give and to receive it. To be a part of it. When it comes to making decisions, I have to ask myself if I’m moving in Love.

 

2. Joy.

Joy is something more than happiness, to me. Joy can look like pain sometimes, if it means I’m honoring my highest self.

3. Freedom.

For most of my life I felt very caged, which helped me realize my deep desire to feel free (while holding healthy boundaries).

 

4. Spirituality.

No construct could keep me away from my need for spiritual connection. With myself, with the divine, with all things.

5. Wisdom.

More than book knowledge, I have always had a penchant for gleaning and growing from not only my life experiences, but the experiences of others.

 

6. Relationship.

Friends, family, romance. These dynamics have always been so near and dear to me. Even as an introvert, I need well-trusted others. They are so important to me.

7. Creativity.

As a writer, musician, artist, what have you, I have always found blissful release in the outlets of creativity. It’s a particular kind of joy that I always want to hold onto.

 

8. Leadership.

Some say you’re born with it, some say you grow into it. Over time, I have stepped further into leadership and discovered: being a leader is part of my purpose.

 

9. Curiosity.

I describe myself as “ever-curious” because there is something innate in me that drives me to figure things out. I find exploration of life’s biggest questions, or even the miniscule dynamics of a romantic conundrum to be so fascinating and pleasurable.

10. Balance.

It is only very recently that I discovered how important balance is in one’s life. For me, it sometimes manifests as the vertical ascension into meditative connection with all things, obliterating the ego; and then subsequently grounding myself in the experience of being a human with the individuality and limitations of this realm, coming back to the ego with compassion.

“Whole Person Coaching is based on the premise that when a person comes to know, embrace and express all aspects of their whole self, they are positioned to thrive throughout their whole life. They become rich in resources, grounded in their being, and at peace within.”

— Feroshia Knight, Master Coach and Founder of CTW

So, how can I help?

 

I know what it feels like.

I’ve been in it. I have felt depressed, anxious, hopeless, confused; like I would always be stuck as a shit-out-of-luck sad girl. But that wasn’t true, and it’s not for you either! Sure, sometimes life might chew you up and spit you back out in the dirt… then stomp on you a few times over for good measure. But as with any hero’s journey, that’s not the end of your story.

I know how to facilitate growth & change.

As a certified professional coach and Applied Positive Psychology Masters of Science graduate, I am able to utilize evidence-based tools, interventions, and approaches to help you self-actualize and achieve your goals.

I know you can do it!

And I am here to help get you there. Through my work and research, I have seen first-hand the transformational power of the human will — especially when one works with a professional. With a little tenacity, hope, resilience, and a cheerleader by your side, I know you can have the life you dream of!
