MODERN & HOLISTIC

Combining a cutting-edge data driven process with a holistic mind/body approach.

It's time to get answers and reclaim your health!

Too often doctors don't have answers to why you are fatigued, having brain fog, gut issues, mood issues, or struggling with inflammatory conditions, much less a process to create true healing and vibrant health.

Fatigue or brain fog ....check
Inflammation....check
Regular blood work....check
Any real answers....NOPE

Advanced functional lab testing gives us the evidence as to why you are feeling the way you do and what is the underlying causes of the inflammation.

You want long-term results, not some fad diet that doesn't really work or band-aid relief with medications or supplements. You also don’t want to waste more time and energy searching for answers only getting more confused about what applies to you.

You are ready to put in the work and discover the root causes, so you can step up on all levels of your life and create a healthier, stronger mind and body!

Testimonials & Clients

Dr. Crystal Whisler is brilliant at finding the tough stuff and helped me zero in on what I was dealing with after months and months of searching. After extensive tests, she uncovered the issues and put me on a targeted and comprehensive protocol which was successful and the key to my health challenges! Thanks, Dr. Crystal!

When I first met with Dr. Whisler, I had been suffering from debilitating fatigue, headaches, joint pain and extreme brain fog for years. I had previously met with a number of other functional doctors, but my health continued to deteriorate. My worst fear was quickly becoming a reality… my boys were growing up without their father. I began to believe no one would be able to help me. When Dr. Whisler found the root cause of my symptoms, I regained hope! She patiently guided me through the ups and downs of recovery. Today, my headaches and joint pain are completely gone and I now have more mental and physical energy than I ever thought possible! Dr. Whisler gave me the ability to enjoy life and dream again!

Dr. Whisler is a phenomenal soul. She is caring, loving, and empathetic towards her patients. She has developed a remarkable program to help those suffering from chronic health issues. I highly endorse her for her work ethic, communication skills, and bedside manner.
Dr. Sachin Patel

Dr. Whisler’s method is effective because she does not merely diagnose, but rather she investigates what causes symptoms to manifest. Her approach to treating my Chronic Fatigue was multifaceted. She made recommendations based on extensive lab testing as well as listening to my experience. By addressing my gut dysbiosis, food allergies, heavy metal toxicity, issues with mycotoxins, and adrenal fatigue I was able to make huge strides. I think it’s rare to find a doctor who views patients as more than lab work and is willing to understand each individual’s complex health puzzle, but Dr. Whisler accomplishes just that.

I consulted with Dr. Whisler about my 3 year old son regarding his chronic constipation and stomach pain. We had visited several doctors and specialists around and had every test run. All we were told was they couldn’t find anything wrong and keep using Miralax. Meanwhile, my son was in misery every day. Dr. Whisler prescribed a dairy free and gluten free diet as well as several supplements. Now my son leads a normal life and so do we.

Before I came to Dr. Whisler, I had just completed radiation and surgery for breast cancer and thyroid cancer. I had let diabetes take over my life. I was overweight, depressed, had sleep apnea, and fibromyalgia to name a few. I felt stuck and frustrated because I had no energy. After a couple of months I started to feel like the old me only better. The weight is dropping off, and I’m now off all my meds for Diabetes and high blood pressure. Also, I am no longer dependent on sleeping pills and pain pills.

When I came to Dr. Crystal, she really listened to me. I was having terrible mood swings, anxiety,insomnia, the kind of pms where you want to kill someone, and fatigue. I was so exhausted. My relationship with my family and my career was suffering. Other doctors had told me I was fine and just wanted to put me back on birth control pills. Dr. Crystal ran hormone tests and nutritional tests on me. I started learning how to take care of myself better and more about how my body works. She put me on a plan with supplements and changed my diet. I have my life back. My energy has returned, I think more calmly and clear, and my pms is just a slight ripple instead of a tidal wave! I learned so much about myself during this process, it's been such a great experience.

When I first found functional medicine and Dr. Whisler, it was my last attempt before I was going to give up. I had been searching for help for years and she is the first one to actually listen and hear what I have to say. She is the first doctor to help me with my fatigue, thyroid and weight loss. I finally know what it feels live to thrive.

I suffered from fibromyalgia, osteoarthritis and many comorbidities including insomnia, headaches, depression, anxiety, obesity, hypertension and hypercholesterolemia. I was at an all-time low and too fatigued and racked with pain to walk from my car to my office. Armed with various test results and under Dr. Whisler’s direction, I began to make better lifestyle choices and am now sleeping well, nearly pain and headache-free, walking to work, hiking, and even teaching outdoor classes. I no longer agonize over whether I will be incapacitated after a trip to the grocery or whether staying up to watch a movie will render me extremely exhausted. I have lost seventy-five pounds. My quality of life has improved immeasurably, and my zest for life has returned. After many years of merely surviving, I feel empowered and invigorated and eagerly anticipate a bright and fulfilling future!

I met with 10 different doctors and none of them could find the problem. I was losing hope. After years of suffering, I finally found Dr. Whisler. She never gave up on me. I now have more energy than I have had in over a decade. My joint pain and muscle pain is gone. The dizziness is gone, my focus is back, and now I get to spend quality time with my kids which I wasn’t able to do in the past.

David

Before working with Dr. Whisler I didn’t have any energy and I was reacting to basically every food group. I had been to a variety of doctors, but none of them gave the answers to what was actually happening. Now, I feel like I finally have my life back. I feel like myself. To not be dealing with brain fog on a constant basis, to enjoying life, and now having more security in my health than I ever have is everything.
