Endless Prescriptions

You get a pill for every problem without your doctor ever checking blood and understaning your full story. You know there has to be a better way to feeling and functioning better.

Struggling with mental health

When actually your brain is malnourished, your hormones imbalanced, or other conditions or exposures are making you feel like your brain is running too fast or in low power mode.

You are more than a diagnosis.

Side effects become their own problem

Weight gain, brain fog, brain zaps, flattened mood, anxiety, or sexual dysfunction feel unnatural and unwanted. Shouldn’t there be a way to feel better without feeling worse?

At Strong Mind Psychiatry, we are here to help you

Feel like yourself again

Tailored precision treatment plan

You get your doctor’s phone number

You will have the doctor’s direct HIPAA secure text messaging so you can reach him when you need him.

Nourish the Brain | Renew the Mind | Restore the Person

I'm Joseph C. Guthrie, MD, and I believe everyone is meant to be well, do good work, and flourish - body, mind, and soul.

I have over 15 years of experience treating the toughest cases of mental disorders.

By combining precision medicine, natural whole-person approaches, and biblical wisdom, I focus on nourishing the brain and nurturing the soul to minimize the use of pharmaceutical drugs and promote better results.

I am a Christian, husband, father, and medical doctor seeking to serve by practicing a reformed psychiatry to help you succeed in what you were created to do—glorify God and enjoy Him forever!

At Strong Mind Psychiatry, we know you are the kind of person who wants to be joyful, productive, and healthy in mind, body, and soul to fulfill the mission and purpose God has willed for your life. 

In order to be that way, you need a well-trained, competent, and compassionate doctor who can give you access to the best tools to uncover the root causes of why you are struggling with how you think, feel, and function to develop treatment solutions that are precise and effective by using the best of medical knowledge with the wisdom of the Bible in a faith-honoring, Christ-centered way for personalized, whole-person care.


The problem is it’s hard to find a psychiatrist with a Christian worldview who is accessible, knowledgeable, patient, interested and takes your faith seriously while offering more than a few minutes in a rushed visit with just another medication, at a higher dose, with more side effects, which makes you feel discouraged and frustrated.

We believe patients deserve better care and better results. No patient should have their legitimate concerns and brain health overlooked, dismissed, or boiled down to just another pill for a diagnostic label while ignoring we were created in the image of God to enjoy His abundant blessings here and now in this world He created.

We understand you are a wonderfully made yet complicated person meant for so much more who has been struggling to find a better way to overcome what has been holding you back and weighing you down.

That’s why we take the time to listen to your concerns, understand who you are, and use actual medical tests to shine a light on the genetic, environmental, nutritional, hormonal, and metabolic factors affecting how your brain functions while considering how your mind can be transformed by biblical truth. 

Here’s how it works. First, you schedule a free 15-minute introductory phone call with Dr. Guthrie. Then, if you both feel it makes sense to move forward and work together, click to schedule your initial visit and be on your way to wellness, so you can stop feeling down, worried, and worn out and, with God’s grace, start feeling, thinking, and being better.
