I'm 50ish and 6'6" so I have a very tenuous relationship with my back. It's always a threat to have an issue and most of them are on the low end, but, every five-ish years my back acts up. When it does it's more than "take two ibuprofen" kind of pain. So every time this happens I've basically found a new chiro and this time was no different. I google searched and Jenny had good reviews and she was literally up the block (insert Jenny from the block reference). In the past, I've generally gone to a chiropractor and it takes 5 or 6 sessions to see results but I went from "this hurts too much to walk a mile" to "good enough to work out" in two sessions. Of course, your results may vary, but I was impressed. I'll be going back in the future and maybe if I treat the small stuff the big stuff will never happen. read more

It almost feels like first world problems to have a Chiropractor, but I'm so glad I have Jenny! I started coming here about a year ago as I just got in a car accident. I didn't feel overly pained, but there was a lot of awkward tightness in my back. A few sessions with Jenny, and my back felt much better. About a year later, I came back when my back suddenly crapped out and I had no idea what to do. I had also reached out to my doctor at Kaiser, as this was a weird sudden pain and I was almost entirely out of commission. Kaiser doctor basically told me to stretch, and take 2 aspirins and call her in the morning. Jenny was awesome in aligning my spine, did a cold laser treatment, and overall tried to advise me on how to get my back righted. She uses a pressure-based treatment, and the first time you come she'll walk you through the process. It really helps because I like knowing what's happening to me, and she made it really easy to understand what she does and why she does it. It's like a mini-crash course on your spine. She takes the time to answer any questions you have, and is very responsive. Appointments can be booked online! Super easy and convenient! read more

12 years and counting! Jenny is still one of the most talented healers I know. I have been seeing chiropractors for more than 35 years. Do not go anywhere else! read more

Jenny is great and really took care of me throughout my pregnancy! I have chronic neck and shoulder pain. I didn't want to go to a chiropractor that did not specialize in prenatal care and the cracking seems too aggressive while I'm pregnant. She uses a different method, using an adjustor that adjusts specific points - it's gentle and effective. I'm so happy I found Jenny. If you're pregnant and need adjustments, I highly recommend Jenny because she is an awesome person and great at what she does. read more

I'm stoked to write a review on Stark Chiropractic! I've seen a lot of Chiropractors in my day and Jenny Proenza is amazing! She not only does great work, she actually listens to her clients, gives great feedback and works with your body and lifestyle in a realistic manner. Highly recommend! read more

I first went to Jenny with pain shooting down the front of my left leg and tingling in the top of my left foot whenever I touched it. I have had issues both with my lower back and upper right shoulder for most of my adult life and for the first time in months, I am pain free. Dr Proenza has fixed me! I cannot convey enough my gratitude for the amazing results that Jenny has produced and I recommend her to everyone I know! If you have every had doubts about chiropractors, this is the place to prove them wrong. read more

Jenny Proenza is my savior!! I came to her with some tension in my neck and shoulders, which ended up being my freakin RIB sticking out, among other things including chronic stress that I carry in those areas!! OUCH! I had no idea. Seriously I thought this was normal. EEK! *No wonder* I had tension, knots and crunchy weirdness in my back, neck and shoulders!!! YIKES!! I came in and did a 1-hour evaluation & treatment with her last week...and then a follow up appointment with her this week She is wonderful. She is sweet, funny & I just feel so comfortable being around her. Her energy is great. She is super smart & is able to explain what is going on without using any jargon. She also has a great space there on 29th at Church. Street parking is easy there & her space is beautiful, clean and easy to find. Not to mention the great restaurants right there if you need to grab a bite before or after. Her technique (using the "activator") is totally gentle, yet effective. And her treatment table is AWESOME. It is hard to explain, but you just stand on a platform & put your face against an erect table that lowers you down. It's way cool! I plan to go see her again next week as well. My first two treatments were so effective, that I am a full believer in the work she is doing. She is reasonably priced & I love her approach. She also is encouraging a holistic approach & has coached me on some ergonomic solutions for my office setup so that I feel better. I received chiropractic treatment years ago in the South Bay in which they adjusted & cracked me left & right. Her activator technique is awesome. I am really impressed. It did not hurt at all & did not involve any cracking. Yet it works!!!! She also has an on site Reiki healer, so you should ask about that while you are there. On another note, she has great connections with massage therapists, an acupuncturist & other health/wellness professionals in the area. So definitely be sure to ask her if you need a referral of any sort! She has good peeps! I am feeling great, thanks to Dr. Jenny Proenza! If you go see her, you will thank yourself later :-) read more

Waste of money! Plus one has to schedule and purchase two sessions to even start. I've seen chiropractors for nearly 20 years, and this wasn't worth it. read more

I am either a chiropractic junkie or connoisseur, depending on your view. Either way, I have regularly seen a chiropractor for over ten years and have developed high standards for what I want. Dr. Proenza exceeds my standards! I have been visiting her every-other-week for about three months now, and am meeting all of my goals. Working with Dr. Proenza helps me get more out of life-- I ski, dance and work with abandon because I know that knocking myself around either because of fun or stress is no problem as Dr. Proenza can get me aligned again and running smoothly quickly. Dr. Proenza takes the time to check my entire spine and anywhere else that troubles me such as my knee, my feet or my hand. She cares about her patients, treats them with care and attention and has an incredible knowledge about what she does. read more

I am always skeptical when it comes to body work. I have gone to chiropractors over the years, and Dr Proenza was the first one to help relieve the daily back pain I have. She is extremely knowledgeable and friendly. Her technique is non-invasive and very effective! I also have Carpal Tunnel and jaw pain. She has worked on these areas as well, and I am SO happy with the results. I couldn't ask for anything more from a chiropractor! She is amazing! If you have back/wrist or any body pain, you must go to Spark Chiropractic! read more

Jenny is an absolute wiz when it comes to getting rid of pain! I suffered from chronic neck and back pain and after moving to California, I tried several chiropractors in search of a gentle, yet effective, approach. Many of the chiropractors I visited did hands-on manipulation, which, when it comes to the neck, always feel quite scary to me. When I found Jenny, it was like I found exactly what I was looking for. Her low-force approach, using a little tool that allows her to adjust specific spots on your body, did wonders for me. With her approach, she could reach precise spots and really enhanced the mobility in my neck. After a few months of seeing Jenny, I felt better than I had in years! I've been seeing her for a few years now and the experience is always fantastic. I'm feeling so much better now that I only have to come in for the occasional touch-up! Jenny definitely started me on the journey to living a pain-free life, and for that I am forever grateful! On top of everything else, Jenny is a wonderful person with a great sense of humor, and it's always really fun to chat and share stories with her! I would recommend Jenny in a heartbeat to anyone looking for a top-notch chiropractor and thoughtful, caring person. Thank you so much for everything, Jenny! You're the best! read more

I was fortunate enough to find out about Spark after winning a bid for two free sessions at a Silent Auction benefiting the MAMA campaign. After a great first impression meeting Dr. Proenza who is super friendly, I received the most thorough, thoughtful and concise consultation about my body, past injuries, etc. followed by an equally detailed report and plan. And the actual adjustments, the best part, are incredibly PRECISE and gentle leaving me walking away with a body that is buzzing and fine-tuned. I will also mention that after falling from an unusually high curb in a small town in Mexico last weekend, leading to a painful strain involving my hip, I walked into her office with a serious limp and couldn't hide the fact that I was panicking. The care and expertise Dr. Proenza provided is beyond impressive. As of today I'm walking normally and have only mild achiness. She has also given me some great ideas of things I can do at home. Ok, one last thing. Dr. Proenza works directly with my insurance company which is no small thing when your a working mother who can't juggle another thing! I'm so grateful. I heart Spark! read more

I've (only) been going to see Jenny for a little over a month now, but so far so great! I haven't had much chiropractic work in the last 20 years, but Jenny came highly recommended to me by a coworker (who happens to be a nurse). I really appreciate her gentle touch and thorough exam. She obviously knows her stuff! My back is feeling much better, and I'll definitely be returning for more adjustments! read more

Gotta say that I have seen a lot of chiropractors and I am very picky about who I let work on me. Dr. Proenza really takes time to find out what is going on with you and lets you know what she is doing the whole time. I had headaches and jaw pain that was killer but that is now gone. I see her know to stay healthy and make sure my headaches never come back again. It sucks to have them and try to work all day! read more

Jenny is fantastic. Our Pilates instructors recommended her and for years she has been taking care of our family and friends through pregnancies, post partum recovery and general life adjustments read more

I sought Dr. Proenza out to help out with healing from a recent ankle injury and to help me with general tension & stress. I broke my ankle & had a surgery several months ago & had been concerned that my range of motion had become really limited. She used some gentle adjustments that seem to have done the trick! My ankle feels much more mobile & my foot is less stiff. I'm happy to have found a chiropractor that doesn't do all the normal cracking! Dr. P is also really smart & had excellent answers to all my questions. Highly recommended! read more

I have been seeing Jenny for nearly two years now on a regular bi-weekly basis. In that time I have grown 3 inches, lost all pain related to my back and feel all around better in my normal everyday health. No, I didn't actually grow anymore, she straghtened out my posture and as a result my actual height came through. I would highly recommend Dr. Jenny to anybody, any age. She's a miracle worker. Cheers, Dale Peronteau read more

Pregnancy without Spark Chiropractic = lunacy! I started seeing Dr. Jenny once per week early in my second trimester. I was having some aches and pains in my low back. Not only did Dr. Jenny keep me pain free throughout the rest of the pregnancy she helped my whole body adapt to the many changes happening as my baby and belly grew. We planned to have our baby at home and after waiting 3 weeks beyond her due date I finally went into labor. I had a very long labor (30 hours!) partly due to the fact that my baby was sunny side up. She was head down but facing forward instead of facing backwards. My midwives said that due to her position she wasn't dropping low enough to accelerate labor. We were trying all sorts of thing to encourage my baby to drop lower and spin around during labor- lying in a twist position during contractions, walking up hills, doing squats and lunges- at 24 hours into labor I was exhausted and worried I'd have to transport to the hospital for induction - something I really didn't want. Thats when Dr. Jenny saved the day. She adjusted me and everything changed! I had renewed strength and after a few more hours not only did the baby drop down but she spun around too! I was able to have the home birth I wanted without any medical intervention thanks to Dr. Jenny! I can't imagine pregnancy without Dr. Jenny's chiropractic care. Her method is gentle and she has a pregnancy pillow so you can lie face-down. And she's super nice! read more

I came to see Jenny last summer with terrible pains in my left hip, which was a constant ache and affected my walk due to the pain. After seeing Jenny I was completely cured of the pain that had been bothering me for months and months, in just a couple of sessions. She has also healed my terrible tennis elbow, which was restricting my daily work. The miraculous recovery that Jenny recently did for me was in my lower back. I had pulled, strained and inflamed all the muscles in my lower back that prevented me to walk without screaming on every step, stand up straight, sit down or lie down without excruciating pain. I felt crippled. I wrote to Jenny first thing the next morning, she replied instantly and fit me in immediately. Just terrific! In 1 session with Jenny's great knowledge and effective methods she enabled me to walk, sit and lie down that day. She literally gave me my back, back....miracle. I recommend Jenny at the highest of levels! She is not only tremendous at her practice but she is also a super person, very sincere and personable. You automatically know you are in good hands when you meet her. Go see Jenny at Sparks, you will be better for it!! Thank you Jenny for taking such great care of me. Cheers! C read more

I found Jenny by chance in April, working next door, went in emergency because I couldn't walk properly from the pain and was about to spend 10 hours in a plane a week later. I discovered this new chiropractic technique, she fixed me up after 2 sessions and I was gone, promising to come back before being in pain! After 5 months I was back but did not go immediately, of course. Instead I waited to be in awful pain, literally carrying my right arm and limping. She did the magic again! Still not getting exactly what she does but she does it right! So if you live with pain, stop messing around with anything else you've been trying until know, call Jenny and start enjoying life again! read more

I can't recommend Spark Chiropractic enough! Having only ever experienced cracky/popping chiropractic care, I was leery of more of the same. But the gentle activator technique and thorough, thoughtful examination combined left me relieved of both immediate pain and a lingering fear of the cracking. Like another reviewer, I had been existing with discomfort, and even pain, without even realizing that I should and could be feeling better. After the first session I felt better on my feet, and after a few I was noticably improved. Thanks! read more

Jenny is nothing short of magic. Her chiropractic style is gentle - no cracking, which I always feared with other chiropractors. Her manner is quiet and thoughtful, and it's clear she truly cares. Her office is comfortable - I feel better as soon as I walk in. She's very thorough and is always on her game - and she does it all in a fun, easygoing way that makes every trip to see her a joy. If you're suffering, don't wait any longer - Jenny will heal whatever ails you! read more

Dr. Proenza is extremely gifted and precise in the work that she does. I don't feel comfortable with high-velocity adjustments that crack the bones to release fixations, so finding Dr. Proenza was a god-send. She uses an activator, which is gentle, yet 100% effective. I can literally feel the energy moving when she finds and then releases a spot that is 'congested.' She is very smart and will discuss in detail aspects of the work, or not, depending on your interests. Either way, going to Spark Chiropractic is a very positive experience and I recommend her highly! read more

The treatment is very gentle, and Jenny is very precise. I love that she takes a holistic view toward my treatment. She is working on much more than just my spine. Also Jenny is very calm and helps you feel comfortable and relaxed. read more

I've been needing the service of a chiropractor since my pregnancy started exacerbating my already-present sciatica last October. I saw some other guy a few times but really wasn't into the whole jarring neck cracking thing. When my doula recommended Spark I decided to give Jenny a chance. What do I love about her? That super cool hydraulic bed, the gentle activator treatments, and the conversation about homebirth (Jenny and her partner had just had a baby). This last week I went to see her and miraculously she said my spine looked pretty good -- first time since October! My sciatica hasn't been bothering me nearly as much in the last couple months, and when I do feel it the pain is more centralized rather than shooting down the leg as it was before. I'm going to continue seeing Jenny for the rest of my pregnancy and definitely beyond. She's a miracle worker! read more

I started seeing Jenny when I was about 5 months pregnant. I was having hip and shoulder pain from sleeping on my side. I immediately saw improvement. I continued to go throughout my pregnancy and after. She help with both chronic and acute issues. I actually saw Jenny the morning I went into labor! I think she helped me relax enough to start labor after my son was born I took him in because we struggled to turn his head to one side and his latch wasn't very open. I saw the adjustment work while we were still in her office. Jenny is gentle, caring and explains things as she goes. I'd recommend her to anyone! read more

Jenny is truly amazing. I suffered through excruciating back and hip pain during my last pregnancy and post partum. Well, I went to go see her and poof...gone. If I ever have another baby I'll definitely be there weekly to keep my back in shape. Gentle, relaxing treatments that are completely effective. Jenny is easy to talk to and really put me at ease my first few times. Plus she's accommodating. I had to bring my sons to a few visits (which I do not recommend!) and she helped me with my fussy baby and crazy toddler. The office is super cute and clean and I enjoy the energy there. I go now for regular tune ups and it's keeping me pain free. I would recommend her to pregnant mammas, post partum moms and anyone in pain. Thank you so much, Jenny!! read more

I've seen Jenny three times now for some chronic pain in my lower back and she is fantastic. Knowledgable, patient and a bedside manner that makes you feel right at home. Most importantly, her treatments are effective: she always gets me back on my feet! read more

Jenny is fun and friendly, and her techniques have released tricky, persistent troubles in my back and neck. If you're nervous about the large, wrenching movements of traditional chiropractic, you don't have to worry here -- the activator method is amazing, non-traumatic, and works! read more

Dr. Jenny Proenza is very smart and educated. Her knowledge of all the human body is very advanced. When you are with Dr. Proenza she is completely present and in tune with what areas need attention. Her technique is targeted and subtle. With results that are very impressive. I walked out completely re-aligned. One of her gifts is the ability to feel the area to target and re-alight the body with no disruption or pain. THE BEST time To See Jenny Is When you are Health. She will support build a sold base for health (spine and nervous system) To insure longevity and vitality. Her office is in a great location and very inviting. She education in the chiropractic is very apparent and I trust her 100%. read more

Dr. Proenza was great. I had never been to a chiropractor before, being scared of all the cracking, it makes my joints unhappy. She was really good at explaining the process and way she adjusts you. I really appreciate that adjustments are done on a table & that Dr.Proenza checks in with you. She helps me through some unusual upper back issues. I'm sticking with her! read more

Jenny is truly, genuinely in this healing business because she cares about each patient's well being. I was a little fearful of going to a chiropractor and was in a lot of pain the first time I went to her office. She thoroughly explained her process and, along with her sparkling personality, put me at ease. She helped to gently realign my neck and upper back and I am so grateful for her upstanding professionalism and kind heart. read more

Jenny changed my experience of pregnancy! I had debilitating back pain in my third trimester and she totally and gently cured it. She is kind and gentle and every time I left there I felt relaxed and healed, thank you Jenny! read more

Jenny is completely awesome!!! I had never been to a chiropractor before since they always scared me. I had extremely painful sciatica and could barely walk. After treatments with Jenny, I can walk fine, bend over, and have not had any pain. Her treatments are absolutely, wonderful, relaxing, and gentle. I highly recommend her for on-going back care. Give yourself some TLC and go to Jenny! read more

I've been having various chiropractic treatments for almost 20 years. I enjoy the Activator Method so much more than I expected! It is completely effective and really easy going. I don't leave feeling all twisted up and vulnerable. Jenny is funny, kind and caring, to boot. :) read more

Seeing Jenny has totally changed my life. I've always been apprehensive of chiropractors because the "cracking" approach seemed quite scary to me. But the type of chiropractic Jenny practices (the activator technique) is incredible - it's so gentle and actually quite relaxing while at the same time incredibly effective. I thought I had carpal tunnel from working on my computer too much and was in so much pain when I first went to Jenny. After the first session it became apparent that I was suffering from chronic stress issues and it was totally messing up my nervous system. And it turns out that nothing was wrong with my wrist - I was just feeling the pain of a way too tense neck all the way down my arm. Working with Jenny has made huge improvements on my life. Not on do I physically feel better, but I'm more knowledgeable about the impact of stress on my nervous system. Every time I get adjusted, I physically feel better, but Jenny is also so awesome that she's been a great support to me as I've figured out how to manage and improve stress overall in my life. She has some fantastic recommendations of things to try and other people to see to support you more holistically. Don't be stubborn or scared of chiropractors - you need to check out this activator technique and Jenny is the perfect person to see. I can't recommend her highly enough! read more

I just had my first session with Dr. Proenza and feel like a million bucks! My posture is so much better already and I feel very energized. She did an evaluation of my whole spine and she also checked my shoulders, knees, and feet. Her style is super gentle-no cracking, folks! She is patient, thorough, and was willing to work with me even though I don't have insurance. If you are looking for a great chiropractor, look no further! read more

I can't say enough good things about Jenny and spark chiropractic! She is extremely caring, thorough, and knowledgeable about the musculoskeletal system. I have seen so many different chiropractors in my lifetime, and I believe that the activator method is the most beneficial. If you are wary of the typical crack methods, the activator technique is for you. It is gentle and extremely precise in aligning your vertebrae and skeletal frame. She has helped me immensely with my chronic neck and shoulder issues! read more

I have been living with chronic ankle pain due to years of sports injuries and the onset of arthritis. An orthopedic surgeon told me I should have my ankle fused. I called Dr. Proenza in search of less invasive options and I am completely amazed and encouraged by the results. In 5 treatments I have regained a significant amount of mobility in my ankle, more than I ever thought possible, and I have experienced a considerable decrease in chronic pain. Dr. Proenza concisely explained the physiology of my injury and mapped out a clear treatment plan. She also provided me with tools and resources I can use to participate in my rehabilitation. I am so thankful for the treatment I am receiving and give Dr. Proenza my highest recommendation. read more
