Our Practice
Threshold Astrology is committed to providing practical, personalized and professional astrological resources.
-
We believe that each person is a co-creative force within the cosmos. While we each have unique potential, we are not tied to a singular fate.
We also believe that you are the authority on yourself. Our role is a partner in your self-exploration, rooted in mutual dialogue and respect.
-
In a world run on algorithms, we are committed to exploring the individual beauty and complexity of each birth chart.
We believe there are multiple layers within each chart. Our goal is to weave together their patterns and connections, revealing a practical path to developing your unique potential. This is what we call an “alchemical” perspective: where others see rust, we see a path to gold.
No AI or cook-book reports. Just the fullness of you in all your radiance.

Our practice is informed by extensive foundational studies with some of the world’s most respected astrologers via Astrology University’s Diploma Program Level I & II Certification.

Diana McNiff
FOUNDER of THRESHOLD ASTROLOGY
Astrology orbited my peripheral vision for many years, colliding with my reality in 2020. Along with the rest of the world, a few months of daily-life in a global pandemic revealed that whatever habits I had unconsciously honed throughout my life just weren’t cutting it anymore. But I was at a loss for how to move forward.
I had my first professional astrological reading and couldn’t look back. The insight it provided was penetrating, genuine and deeply personal. It planted the seeds of new perspectives in my mind. What I saw before as innate internal challenges began to transform into unique gifts.
Unknowingly honoring the Sagittarian Saturn on my Ascendant, I voraciously and systematically sought deeper knowledge through completion of Astrology University’s Diploma Certification program, which led me to envision and launch Threshold Astrology in 2023.
Prior to founding Threshold Astrology, I explored a few other iterations of myself that led me to this work. Read the rest of the story below.

In addition to extensive self-study, Diana McNiff (Founder of Threshold Astrology) has completed Astrology University’s Diploma Program.
Through this program, I have studied with some of the world’s most respected astrologers including Tony Howard, Demetra George, Kelly Surtees, Darby Costello, Lynn Bell, Mark Jones, Jessica Murray, Karen Hamaker-Zondag, Jason Holley and Steven Forrest.
My practice is also deeply influenced by the teachings of Dane Rudhyar, Stephen Arroyo, Erin Sullivan, Bernadette Brady, Chani Nicholas and Chris Brennan.

My approach draws from the earned wisdom of my own unfolding story, including psychotherapeutic training, a decade of international development work, artistic expression as a singer-songwriter, and my daily journey of creating a family alongside my partner as we raise two growing humans. These experiences feed the metaphors and imagery that arise from each client's chart, and support my ability to meet each client wherever they are in their unique journey.
Parallel to my astrological practice, I completed a Masters in Clinical Social Work from Rutgers School of Social Work in 2026. I am honored to work with people in these two distinct spaces, each offering its own opportunities and tools for exploration and insight.
“Diana is insightful and well versed in her craft. I got so much out of our sessions. I can’t recommend working with her enough!”
“I’d been looking for a way to increase my sense of self-awareness with all of the changes in my personal and professional life post-covid. I’d changed careers, became a parent to another child, and many of my relationships had shifted in the process.
At first, I wasn’t sure astrology would give me the answers I needed, but Diana really is an expert. The way she explains astrology is refreshing and relatable. She provides clear context for what can seem like daunting, nebulous ideas. Diana brings astrology down to earth so you can use it to your own advantage.”
“Diana has been a very important person in my personal growth journey. She brings so much wisdom, integrity, knowledge and preparation to her chart readings, and is always able to provide thoughtful insights into my life that I wasn’t able to see before. She is open and easy to talk to, a great listener, and has a grounded and honest approach to help you consciously engage with the specific energies of your chart.
I have found astrology to be a truly life-giving tool, and I highly suggest allowing Diana to be your guide through the intricate map that is your birth chart.”
“My readings with Diana have been truly life changing. She is great for both the astrology novice (like me) or those who have been exploring this field for some time. She does a fabulous job diving into the layered details but explaining them in easy to understand ways. I previously was somewhat dubious about astrology but now I am a full believer thanks to my experience with Diana.”
“Between stimulus and response there is a space.
In that space is our power to choose our response.
In our response lies our growth and our freedom.”
