Free in-person event: Take Control of Your Mental Health
It’s time to take control of your mental health. How do you get rid of stress, anxiety and uncertainty? These emotions are buried deep in your reactive mind. Find out what the reactive mind is, and in the process find yourself.
Have you ever suffered from a traumatic experience, a deep loss or been through a painful breakup? Has your ability to communicate suffered as a result? And after that, even though you "moved on" did you find that things were never quite the same? Have you ever looked at childhood photos, or reminisced your early life and wondered where that happiness and spark went?
Are your emotions out of your own control? Have you ever felt, even if you aren’t aware of it, that possibly you are getting in your own way of your happiness and success? How does this affect your self-confidence?
Find out what is at the root of all stress, anxiety, depression and self-doubt. Find out how and why you hold yourself back from achieving your goals and having the life you have dreamed of. As soon as you learn what is at the root of these unwanted conditions, you’ll see it is something you can DO something about. You will not be labeled or categorized at this MeetUp.

Free In-person Meeting: Unwanted Emotions & Loneliness, How to Get Over Them
This is an in-person meeting.
Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance.
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues.
So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them?
That is what this meeting will be all about.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.

Free In-Person Meeting: Get Over Losses & Betrayals, Build Lasting Relationships
This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships.
Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse.
Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well.
Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship.
Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action?
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships!
Break free from self imposed limitations
Here we will discuss:
• How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes.
• Why and how do the negative emotions of others affect you?
• Why is my partner withdrawing and what can I do about it?
• Why do we sometimes feel compelled to hurt the ones we love?
• Fights & arguments - what's really behind them?
• What underlies “corrosive criticism” or the need to invalidate self or others?
• How one can stably change one’s outlook on life so they can affect positive change?
• Where do compulsive destructive behaviors come from and what can be done about them?
• How to form closer bonds & keep growing the relationships with the people you care about?
• How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career?
Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general.
Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person.
Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life.
We look forward to having you join us!

Volunteer Opportunity
Open Shelter has teamed up again with Red White and Boom! Friday, July 3rd & we are looking for volunteers to run the event’s alcohol booths. Proceeds from sales go to the Open Shelter’s organization.
There are two available shifts: 12-6p & 5-11p.
There will be an ipad-like device to process transactions in addition to cash. Everything will be in bottles or cans, so transactions should be very easy. Must be 21+.

Stop Guessing: How to Measure and Improve LLM Outputs
Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on.
That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable.
In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork.
This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it.
We’ll cover:
* Why “it looks good” is not enough
* How to improve prompts by changing the input, context, and constraints
* How to compare LLM outputs more systematically
* Basic evaluation techniques for accuracy, consistency, and usefulness
* How embeddings, cosine similarity, and scoring can help evaluate results
* Where automated evaluation works — and where humans still need to stay in the loop
By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve.
LOGISTICS AND PARKING:
The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks!
The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
Humanist Program
This presentation will be by Ben Iten, humanist chaplain and HCCO Board Member. Speaking on expressing Humanism values in American democracy.

Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk.
The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event.
