Dr. Mondala exceeded my expectations of functional medicine. She is detailed in her questions seeking to understand not only your physical health but also your spiritual health. She truly seeks to understand and care for the whole person. I am not a vegan, but she supports my nutrition and encourages me to try to incorporate new foods and recipes. She’s caring and thorough. I highly recommend her.

Diane G.

 

Dr. Micah Yu is the absolute best. He has been very informative about my issues with Auto Immune Dieases. Prior to him becoming my doctor I had no idea what really was going on with my body. Because of him I’ve stopped smoking and am eating somewhat healthier. He’s compassionate and cares about his patients. He is leaving the facility where I have been treated however wherever he goes he’ll definitely be an asset to all he encounters. Love you Dr. Yu.

OMG! Best doctor ever- AMAZING! I take my health extremely seriously (life is too precious and short not too). A REAL doctor concerned with your life, not just the symptom. She is incredibly knowledgeable, supportive, and present. It is as if you have an expert coach, confidante and physician accompanying you on the ups and downs of the life journey with you. I could never return to the regular medical model physician after experiencing Dr. Mondala. Simply THE best!

Maryloyola Y.

 

Dr. Yu is absolutely amazing. I went through two rheumatologists and a fancy primary care clinic before finding Dr. Yu. I have rheumatoid arthritis and Dr. Yu’s protocols are a mix of traditional medicine and integrative health, which is exactly what I was looking for. I was struggling to find someone who cared about the holistic-health approach, and Dr. Yu ended up being the perfect fit! You can tell he cares about his patients and is incredibly knowledgeable. I highly recommend

Sarah A.

 

Dr. Yu is a great doctor who gave me a second opinion for my ankylosing spondylitis. He’s given me more pathways to consider on top the standard treatment, including a lot of information on diet, exercise, supplements, and general life with ankylosing spondylitis.

Billy G.

 

Making the switch to Dr. Mondala as my primary care physician has filled my life with positivity and support. She takes her time with me and is always available when I need to see her. She has such a great wholistic approach to healing and wellbeing and I am so grateful to have her in my life.

Susan A.

 

Dr. Mondala has been the best primary care physician I have been to. She goes above and beyond for caring for me and my family whether its through traditional means or her lifestyle care. She always answers all my questions and concerns no matter the day or time. Anyone who chooses to have her as her PCP is doing themself a favor.

Starting Your Care with Dr. Lifestyle

Begin the conversation

Starting care is simple. When you request an
appointment, you’ll create secure access to our
patient portal — the space where your care
journey begins.

New patients complete a brief registration so we can understand your needs before your first visit. You’ll receive an email to activate your account and continue when you’re ready.

Shape your visit

Once you’re logged in, you’ll be guided through scheduling your appointment — choosing the provider, visit type, and time that best fits your needs.

Our process is designed to be flexible and intentional, allowing space for the kind of care that goes beyond rushed visits.

Ongoing, supported care

After scheduling, you’ll receive confirmation and next steps by email. Upcoming appointments and care details will always be available in your portal.

From here, our focus shifts to continuity — supporting you before, during, and after visits as part of a longer-term care relationship.

The Problem

When care focuses only on symptoms

Short-term relief may help temporarily, but without understanding the underlying causes, symptoms often return—or shift elsewhere.

THE SOLUTION

A more comprehensive approach to long-term health

Integrative medicine looks beyond isolated symptoms to understand how lifestyle, environment, nutrition, and physiology interact. When appropriate, this approach can reduce reliance on medications — while always prioritizing safety, evidence, and individual needs

HOW TO CONNECT

Care that fits your life
