You deserve to understand
why โ and a plan that actually helps.
Whether you've been trying for months, navigating a diagnosis, preparing for IVF, or just starting to ask questions โ Dr. Alissia Zenhausern-Pfeiffer, NMD, FABNE provides evidence-based, integrative fertility care that goes deeper than "everything looks normal."
"I finally felt like I was working with my body instead of against it. Now, after having our son, I tell all my friends to go see her."
โ Caroline D., NMD Wellness PatientYou know something is wrong.
You're done waiting to find out what.
Most of our fertility patients have already seen other providers. They've been told their labs are normal, given a prescription without an explanation, or simply told to keep trying and come back in a year. They arrive here exhausted โ and they leave with answers.
Trying to conceive naturally
You want to understand your cycle, know what your labs actually mean, and have a strategic plan โ not just a supplement list and hope.
Preparing for IVF or FET
You want to do everything possible to improve your retrieval outcomes, embryo quality, and implantation success. The 90 days before your cycle matter more than most people realize.
After failed cycles
You've been through IVF that didn't work, or pregnancies that didn't stick. You need someone who will look at what's being missed โ not just try the same thing again.
PCOS or thyroid diagnosis
You have a diagnosis but not a plan. You want to understand how it's affecting your fertility and what to actually do about it โ not just manage symptoms.
Secondary infertility
You've been pregnant before. That doesn't explain what's happening now โ and it doesn't mean you should wait another year before getting answers.
Proactive preconception
You're not trying yet but you want to start right. Optimizing your hormonal health before you begin gives every future cycle the strongest possible foundation.
Evidence-based integrative care
for every fertility challenge.
We are not a wellness clinic with a supplement protocol and a hopeful attitude. Every recommendation is grounded in clinical research. Every lab we order has a reason. This is why reproductive endocrinologists and OB-GYNs across Arizona refer their patients to us.
Care that actually investigates.
A plan that actually moves.
Most fertility patients come to us after years of fragmented appointments. Here, your care is continuous, strategic, and built entirely around your specific case.
Your discovery call
A real conversation โ not a sales call. Dr. Zen reviews your intake before you speak so your first interaction is already about your specific case. You'll leave with clarity on whether and how she can help.
Comprehensive initial evaluation
A deep-dive into your full health history, prior labs, current symptoms, cycle patterns, and fertility goals. Nothing is dismissed. Everything is considered. This is where the dots get connected.
Strategic lab review & protocol
We run the labs that don't get ordered โ and interpret them against optimal ranges, not just "within normal limits." Your protocol is built from your actual data: nutrition, supplementation, lifestyle, and medication when clinically indicated.
Ongoing concierge care
Priority scheduling, direct messaging access to Dr. Zen, and regular follow-ups that adjust as your labs and your body change. You're never left alone between appointments waiting for answers.
Through every season
From preconception through IVF, pregnancy, and postpartum โ your care evolves with you. Members who conceive receive seamless support into pregnancy and the first postpartum year. Because the journey doesn't end at a positive test.
Real women. Real results.
In their own words.
"Before Dr. Zen, I felt overwhelmed by the idea that I would never get pregnant. I'd been seen by countless doctors and told IVF was my only option. I finally felt heard โ like I was part of my own fertility care. I always called her my health detective. After years of infertility, I was finally working with my body instead of against it. Now, after having our son, I tell all my friends to go see her."โ Caroline D.
"After an at-home hormone test, I realized I had low ovarian reserve and was utterly shocked. Dr. Zen not only identified that I had Hashimoto's โ something no one had caught โ her care plan helped me lower my thyroid antibodies, improve my thyroid function, and even improve my AMH levels. We are now 22 weeks pregnant with our daughter."โ Lauren B.
"I'd been struggling with debilitating periods for years and had done 4 laparoscopic procedures โ each giving me only temporary relief. I honestly thought this was just my life. I was skeptical Dr. Zen could help without surgery. But after working with her for 3 months, I barely notice my periods. My only regret was not seeing her sooner."โ Jess M.
"Hi Dr. Zen! I just wanted to circle back and let you know that my beautiful, sweet daughter was born! She is the sweetest, chillest, happiest, most easy-going baby I could have ever imagined. She was definitely missing from our family. I feel so blessed that we were able to add one more baby to the mix, especially at my ripe age of 40. She was born at 38+4, no induction, and 6 lbs 5 oz! Never in my wildest dreams did I ever imagine I'd be a mother of 3. Forever grateful to you."โ Lauren
Dr. Alissia Zenhausern-Pfeiffer, NMD, FABNE
As a mother who has navigated her own fertility journey, Dr. Zen brings both clinical expertise and genuine personal understanding to every patient she sees. She is one of a small number of naturopathic doctors in the country who holds the FABNE designation โ Fellow of the American Board of Naturopathic Endocrinology โ representing advanced specialty training beyond the naturopathic medical degree.
Her approach combines the rigor of evidence-based medicine with the depth of integrative care. She runs comprehensive labs, interprets them against optimal ranges, and builds treatment plans that address root causes โ not symptoms. It's the reason REIs and OB-GYNs across Arizona consistently refer their most complex fertility patients to her.
Naturopathic fertility care isn't alternative.
It's additive.
Your REI focuses on the mechanics of reproduction โ egg retrieval, embryo transfer, assisted fertilization. What naturopathic endocrinology adds is the biological foundation those procedures depend on: hormonal balance, metabolic health, thyroid optimization, egg quality, uterine environment, and immune regulation.
These aren't soft variables. They are clinically significant factors that affect whether cycles work โ and they're often exactly what's being missed in fragmented conventional care.
Before you book.
- Thyroid โ TSH, Free T3, Free T4, TPO & thyroglobulin antibodies
- Ovarian reserve โ AMH, FSH, LH, estradiol (day 3), antral follicle count
- Full sex hormone panel โ estradiol, progesterone, testosterone, DHEA-S
- Insulin resistance & metabolic markers โ fasting glucose, insulin, HbA1c
- Inflammation โ CRP, homocysteine
- Nutrient status โ vitamin D, B12, ferritin, folate
You've spent enough time
wondering.
A discovery call costs you nothing but a conversation. Dr. Zen will review your intake before you speak โ so from the very first moment, your care is already personal.
