About
Hi, I’m Doug Jaser
I began my career interested in creativity and consciousness, studying art and literature in undergrad. I was drawn to work that expressed perspectives I believed were true and valuable, even where they weren't yet widely accepted.
During my junior year, my father had a stroke. It reset how I saw the world. Working with him and the medical team through his recovery, one question stuck with me: the doctors were focused on keeping him alive — but staying alive and actually living well aren't the same thing, and nobody seemed to be addressing the second part. That gap is what I've spent my career on since.
Most people don't think about their health at all until something forces them to — it's not something they feel is out of reach, it's just not on the radar until it becomes unavoidable. I wanted to help people close that gap before the forcing moment, not scramble to catch up after it.
That question shaped the last fifteen years of my work: understanding health through lifestyle, physiology, and the individual person in front of me, not just a chart of symptoms.
What's changed more recently is how I do that work. Over the last few years I've built real data analytics skills alongside the clinical side — not because measuring things is the point, but because of what becomes visible once you can actually see the pattern. Which of the changes you're making are the ones actually moving things for you, specifically — not what works in general. Whether how you're feeling really does line up with what you've been doing, or whether something else is driving it. Risks that don't show up in a single conversation, but do show up once you can see a trend. That's the real shift: turning confusion into something clear and visible.
I help working professionals who are feeling unsettled by the pace of change around them — career shifts, AI reshaping their industries, a world that feels less predictable than it used to. My approach pairs a steady, consistent presence with a preventive, evidence-grounded system, built to move you from surviving a hard stretch to genuinely thriving again — not by following a template, but by uncovering what's real and true for you.

Health and lifestyle coaching since 2011, including roles at Pharmaca Integrative Pharmacy and as Resident Nutrition Coach at Renaissance ClubSport Walnut Creek.

Research:
I served on the clinical team for a published precision-medicine study on reversing early cognitive decline, conducted across three sites including Bay Area Wellness in Walnut Creek.
Toups, K., Hathaway, A., Gordon, D., et al. (including Dale E. Bredesen). "Precision Medicine Approach to Alzheimer's Disease: Successful Pilot Project." Journal of Alzheimer's Disease, 2022. [Read the full paper — open access]
Over 9 months, 84% of participants showed cognitive improvement across multiple independent measures, including standardized testing and brain MRI. I'm acknowledged by name in the publication for my clinical contribution.
This was a proof-of-concept pilot study — 25 participants, no control group — not a claim that any single protocol is proven. It supported moving forward to a larger randomized controlled trial, which followed.
Based in Walnut Creek, CA. Available virtually by phone or video call.

“I’m very impressed with Doug’s nutritional skills. I decided to have him work on a personalized meal plan for me. The daily caloric intake was well below what I normally eat and I was worried about feeling famished. He has balanced the fat and protein so well that hunger hasn’t been an issue. I have been losing 2 lbs of body fat a week with minimal loss of muscle and I’ve been able to keep increasing the weights in my strength training routine. I expect to get to my goal of losing twenty pounds one month ahead of schedule. . I’m down to 189 lbs from a starting point of 201. I have no hesitation in recommending Doug’s nutrition services.”
“Doug has been a big help to me on my way to better health! Through his guidance not only have I lost weight but I’m sleeping better, my joint pain has been reduced, and I feel that I have more energy. I really know now how diet plays a major role in one’s overall health and well-being along with exercise, stress management, and spiritual and social well being. Look forward to working with you again in the future.”
Willpower can only get you so far. You need to understand your needs and motivations in order to make change last.
My goal is to help make health improvement as easy as possible for you.
I believe the most effective way to accomplish this is by changing subconscious, daily habits over a long period of time. Your lifestyle is the foundation upon which your health is determined. It is more important than your genetics. Changing your lifestyle is hard. It is well documented that most of us fail to change our diets, exercise more, lose weight, etc.
I will work in partnership with you by blending health education, health coaching, and functional nutrition*. I focus on understanding you: your motivations, your goals, your symptoms, as well as your preferences.
Over time, you will learn how to improve energy production in your cells and balance your digestive ecosystem.
I aim to be attuned to your needs. We will work to uncover what is going on for you and devise a plan to get to where you want to be. I will teach you which organs and systems are mostly at play with your health concerns and how to improve their function by adjusting your habits and environment. My approach focuses on partnership so you can show up exactly as you are, knowing that I will not try to push changes on you that you are not interested in. I will explain what is likely happening in your body, the probable causes, and the benefits of certain lifestyle changes. We can discuss the advantages and obstacles to those changes and decide on a plan that works for you. It should be noted that the more change you are willing to make the more positive the results you can expect to see over time.
Improving your lifestyle will lead to a better foundation of health. Investigating what is going on in your body will help us figure out what is getting in the way of even better health. And experimenting with safe lifestyle and supplement options will help us get the most from your efforts.
You may find that you have never been engaged in such a proactive way to improve your well-being. It is my goal that you find making positive lifestyle changes as easy as possible and even enjoyable.
